jQuery how to check if event is already bound

Why is it important to check if an event is already bound To prevent attaching event handler multiple times The following example checks if a click event handler is already bound. If it's not already bound, then a click event handler is attached. Replace < with LESSTHAN symbol and > with GREATERTHAN symbol <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { var jQueryObject = $('#btn'); var rawDOMElement = jQueryObject.get(0); var eventObject = $._data(rawDOMElement, 'events'); if (eventObject != undefined && eventObject.click != undefined) { alert('Click event exists'); } else { $('#btn').on('click', function () { alert('Button Clicked'); }); } }); </script> </head> <body style="font-family:Arial"> <input id="btn" type="button" value="Click Me" /> </body> </html> Please note that this only works if you have attached event handlers using jQuery. This will not work if you have attached event handlers using raw JavaScript or element attributes. Another way to prevent attaching event handlers multiple times is by using jQuery off() and on() methods. The off() method ensures that all existing click event handlers of the button are removed before again adding a new click event handler using on() method. $('#btn').off('click').on('click', function () { alert('Button Clicked'); });

jQuery #id selector
 
10:53
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/03/jquery-id-selector.html In this video we will discuss 1. What are jQuery selectors 2. Different selectors in jQuery 3. #id selector in jquery What are jQuery selectors One of the most important concept in jQuery is selectors. jQuery selectors allow you to select and manipulate HTML elements. Different selectors in jQuery jQuery selectors allow you to select html elements in the DOM by 1. Element ID 2. Element Tag Name 3. Element Class Name 4. Element attribute 5. Element Attribute values and many more Id selector in jquery To find an HTML element by ID, use the jQuery #id selector Example : The following example finds button with ID button1 and attaches the click event handler. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').click(function () { alert('jQuery Tuorial'); }); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] Changes the background colour of the button to yellow $(document).ready(function () { $('#button1').css('background-color', 'yellow'); }); Important points to remember about jQuery #id selector 1. jQuery #id selector uses the JavaScript document.getElementById() function 2. jQuery #id selector is the most efficient among all jQuery selectors. If you know the id of an element that you want to find, then always use the #id selector. 3. HTML element IDs must be unique on the page. jQuery #id selector returns only the first element, if you have 2 or more elements with the same ID. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { $('#button1').css('background-Color', 'yellow'); }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [input id="button1" type="button" value="Click Button" /] [/body] [/html] 4. JavaScript's document.getElementById() function throws an error if the element with the given id is not found, where as jQuery #id selector will not throw an error. To check if an element is returned by the #id selector use length property. [html] [head] [title][/title] [script src="jquery-1.11.2.js"][/script] [script type="text/javascript"] $(document).ready(function () { if ($('#button1').length ] 0) { alert('Element found') } else { alert('Element not found') } }); [/script] [/head] [body] [input id="button1" type="button" value="Click Me" /] [/body] [/html] 5. JavaScript's document.getElementById() and jQuery(#id) selector are not the same. document.getElementById() returns a raw DOM object where as jQuery('#id') selector returns a jQuery object that wraps the DOM object and provides jQuery methods. This is the reason you are able to call jQuery methods like css(), click() on the object returned by jQuery. To get the underlying DOM object from a jQuery object write $('#id')[0] 6. document.getElementById() is faster than jQuery('#id') selector. Use document.getElementById() over jQuery('#id') selector unless you need the extra functionality provided by the jQuery object.

Why You Don't Need jQuery Anymore
 
01:01:38
jQuery was a wonderful tool that paved over the irregularities of browsers and offered a simple interface for making very powerful applications. Today with evergreen browsers and modern JavaScript, we no longer need this crutch. Let’s look at our favorite jQuery techniques like $.ajax() and $(…).click() and $(…).addClass() and compare this to the code we’d write in modern JavaScript. Sprinkled in are great ES6 techniques like rest and spread, promises and fetch. Challenge yourself on your next project to see if you can run in a post-jQuery world. NOTE: You still might want to learn jQuery because many companies still use it.

This widget is in interactions category on the jQuery UI website. http://jqueryui.com/draggable/ Consider the following HTML <div id="draggableDiv" class="divClass"> Drag me around </div> .divClass { height: 200px; width: 200px; background-color: red; color: white; display:table-cell; vertical-align:middle; text-align:center; } To make the above div element draggable $('#draggableDiv').draggable(); Some of the useful options to customize the draggable widget axis - Constrains dragging to either x or y axis containment - Constrains dragging to within the bounds of the specified element or region cursor - The CSS style of the cursor during the drag operation opacity - opacity during the drag operation revert - Boolean property that specifies if the element should revert to its start position when dragging stops revertDuration - The duration of the revert animation, in milliseconds snap - Specifies whether the element being dragged should snap to other elements. Value can be boolean or a selector. When set to true, the element will snap to all other draggable elements. When a selector is specified the element being dragged will snap to the element specified by the selector snapTolerance - The distance in pixels between the element being dragged and the element to which to snap to, at which snapping should occur. cancel - Prevents dragging from starting on specified elements Constrains dragging to x axis $('#draggableDiv').draggable({ axis : 'x' }); Constrains dragging to within the bounds of the parent element HTML <div id="containerDiv" style="height:300px; width:300px; border:3px solid black"> <div id="draggableDiv" class="divClass"> Drag me around </div> </div> jQuery $('#draggableDiv').draggable({ containment : 'parent' }); Changes the cursor style to "move" during the drag operation $('#draggableDiv').draggable({ cursor: 'move' }); Changes the opacity to 0.3 during the drag operation $('#draggableDiv').draggable({ opacity : '0.3' }); Reverts the div element to its start position when dragging stops. Revert animation completes in 1000 milli-seconds. $('#draggableDiv').draggable({ revert: true, revertDuration : 1000 }); The following example 1. Snaps the coloured div elements to the div element with thick black border. 2. The snapping occurs as soon as the distance between any of the coloured div element and the div element with thick black border is 50 pixels 3. The cancel option cancels dragging from starting on the div element with thick black border HTML <div id="redDiv" class="divClass" style="background-color: red"> Red Div </div> <div id="greeDiv" class="divClass" style="background-color: green"> Green Div </div> <div id="blueDiv" class="divClass" style="background-color: blue"> Blue Div </div> <div id="brownDiv" class="divClass" style="background-color: brown"> Brown Div </div> <br /> <br /> <div id="snapDiv" style="height: 400px; width: 400px; border: 5px solid black"> </div> Style .divClass { height: 200px; width: 200px; color: white; display: table-cell; vertical-align: middle; text-align: center; } jQuery $('div').draggable({ snap: '#snapDiv', snapTolerance: 50, cancel : '#snapDiv' });

jQuery add event handler to dynamically created element
 
09:15
Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/04/jquery-add-event-handler-to-dynamically.html In this video we will discuss, how to add event handlers to dynamically created elements. Let us understand this with an example. The following example, allows us to dynamically create new list item (li), attach a click event handler and add it to the unordered list (ul). This happens when you click "Add a New List Item" button. The problem with this approach is that we are binding a click event handler to every list item. This means if you have 500 list items, then there will be 500 event handlers in the memory and this may negatively affect the performance of your application. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('li').on('click', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { var newListItem = $('<li>New List Item</li>').on('click', function () { $(this).fadeOut(500); }); $('ul').append(newListItem); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html> A better way of doing the same from a performance standpoint is shown below. In this example, the click event handler is attached to the listitem (li) parent element (ul). Even if you have 500 list items, there is only one click event handler in memory. So how does this work 1. When you click on a list item (li), the event gets bubbled up to its parent (ul) as the list item (li) does not have an event handler 2. The bubbled event is handled by the the parent (ul) element, as it has a click event handler. 3. When a new list item is added dynamicaly, you don't have to add the click event handler to it. Since the newly created list item (li) is added to the same parent element (ul), the click event of this list item also gets bubbled upto the same parent and will be handled by it. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('ul').on('click', 'li', function () { $(this).fadeOut(500); }); $('#btnAdd').on('click', function () { $('ul').append('<li>New List Item</li>'); }); }); </script> </head> <body style="font-family:Arial"> <input id="btnAdd" type="button" value="Add a New List Item" /> <ul> <li>List Item</li> <li>List Item</li> </ul> </body> </html>

Replace < with LESSTHAN symbol and > with GREATERTHAN Symbol. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> </head> <body style="font-family:Arial"> First Name : <input type="text" value="John" /> <br /><br /> Last Name : <input type="text" value="Major" /> <br /><br /> Gender : <input type="radio" name="gender" checked="checked" value="Male">Male <input type="radio" name="gender" value="Female">Female <br /><br /> Skills : <input type="checkbox" name="skills" checked="checked" value="JavaScript" />JavaScript <input type="checkbox" name="skills" checked="checked" value="jQuery" />jQuery <input type="checkbox" name="skills" value="C#" />C# <br /><br /> Country: <select> <option selected="selected" value="USA">USA</option> <option value="India">India</option> <option value="UK">UK</option> </select> <br /><br /> Summary : <br /> <textarea>I am a Senior Dot Net Developer with 10 years experience</textarea> <br /><br /> <input type="submit" value="submit" /> </body> </html> Now we want to get the text value from all the textboxes. On this page we have 2 textboxes 1. First Name 2. Last Name jQuery code to get textbox value using $(input) <script type="text/javascript"> $(document).ready(function () { $('input[type="text"]').each(function () { alert($(this).val()); }); }); </script> jQuery code to get textbox value using $(:input) <script type="text/javascript"> $(document).ready(function () { $(':input[type="text"]').each(function () { alert($(this).val()); }); }); </script> Which one is better for performance $('input[type="text"]') or $(':input[type="text"]') $('input[type="text"]') is better for performance over $(':input[type="text"]'). This is because $(':input[type="text"]') needs to scan all input elements, textarea, select etc, where as $('input[type="text"]') scans only input elements. So if you want to find elements with an input tag, it is always better to use $('input[type="text"]') over $(':input[type="text"]')

To create mobile applications most developers have to learn a brand new language such as Swift of Java. However, that's not the case if you use the PhoneGap library. The PhoneGap library can allow you to create apps that can be distributed in the Apple App Store and the Google Play Store. I've found that the reason that most people don't learn to create mobile apps is that they don't have the time to learn new skills. That's where PhoneGap comes in-- You'll learn to create mobile apps using the languages you already know-- HTML and Javascript. The kinds of apps you can produce are virtually endless. In this video you'll learn how to style your PhoneGap app in just about 30 seconds using the jQuery Mobile library.

How to make elements disappear in jQuery - Learn jQuery front-end programming. In this lesson we will learn how to make HTML elements appear and disappear inside our websites. We will do this using the jQuery effects called show, hide, and fade. Download lesson files: http://mmtuts.net/course.php?c=jquery&l=5 -- mmtuts is a YouTube channel that focuses on teaching beginner and advanced courses in various multimedia related skills. We plan to make tutorials available on programming, video production, animation, graphic design, and on software such as the Adobe Creative Cloud programs. jQuery for beginners is a how to series that teaches the jQuery framework to people who are just starting out learning programming. The course teaches how jQuery scripting can be made easy and teaches how to build many features on websites through behavior using jQuery. Creating behavior on websites with jQuery is easy and should not be seen as otherwise, which is why we want to explain the language in a easy to understand way for beginners.

Build a responsive navigation with CSS and jQuery - with a bonus dropdown effect using CSS clip-path
 
50:43
In this video I look at how to create a responsive menu using jQuery. It’s a bit of a long video where we build out the menu from scratch with HTML, then styling the menu with CSS, before finally using a bit of jQuery to get it to work. Once it's all set up and working, I use a CSS clipping path to give it a bit of a cool animation for when it toggles in and out. I also create my own hamburger menu using pseudo elements and some CSS, creating a custom animation for it with another CSS class and a bit more jQuery. If you’d like to skip to any specific part, the times for all the steps are below, and if you want to play with the code, it's on Codepen - http://codepen.io/kevinpowell/pen/PWNwZm Starting at 02:20 I look at simply building out a vertical menu. At 12:20 I add the hamburger menu At 19:50 I use a little simply bit of jQuery to get the mobile menu to toggle on and off Starting at 24:50 I look at animating the hamburger menu. Then at 28:46 I look at adding in some icons with Font Awesome With the mobile version done, at 37:50 I add a media query so that it is a normal, horizontal navigation on larger screens. Then at 42:00, with the whole thing wrapped up, I change the animation to use clip-path to make the toggling animation a little more interesting, and then fix up a few little loose ends. --- Music by Chillhop: http://youtube.com/chillhopdotcom Mo Anando - In Bloom: https://soundcloud.com/moanando If you have your own channel, check out Chillhop for some awesome music.

jQuery to detect which mouse button clicked

With raw JavaScript event object : Depending on the browser, event.button or event.which properties of the event object are used to determine which mouse button is clicked. IE 8 & earlier versions use event.button property Left Button 1 Middle Button 4 Right Button 2 IE 9 & later versions and most other W3C compliant browsers use event.which property Left Button 1 Middle Button 2 Right Button 3 If you are using raw JavaScript event object, the following is the amount of code that you have to write to detect which mouse button is clicked. This code works in all browsers. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> function whichMouseButtonClicked(event) { var whichButton; if (event.which) { switch (event.which) { case 1: whichButton = "Left Button Clicked"; break; case 2: whichButton = "Middle Button Clicked"; break; case 3: whichButton = "Right Button Clicked"; break; default: whichButton = "Invalid Button Clicked"; break; } } else { switch (event.button) { case 1: whichButton = "Left Button Clicked"; break; case 4: whichButton = "Middle Button Clicked"; break; case 2: whichButton = "Right Button Clicked"; break; default: whichButton = "Invalid Button Clicked"; break; } } document.getElementById('divResult').innerHTML = whichButton; } </script> </head> <body style="font-family:Arial"> <input id="btn" type="button" value="Click Me" onmouseup="whichMouseButtonClicked(event)" /> <br /><br /> <div id="divResult"></div> </body> </html> jQuery normalizes which property of the event object so it will work across all browsers. The amount of code you have to write is lot less. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btn').mouseup(function (event) { switch (event.which) { case 1: whichButton = "Left Button Clicked"; break; case 2: whichButton = "Middle Button Clicked"; break; case 3: whichButton = "Right Button Clicked"; break; default: whichButton = "Invalid Button Clicked"; break; } $('#divResult').html(whichButton); }); }); </script> </head> <body style="font-family:Arial"> <input id="btn" type="button" value="Click Me" /> <br /><br /> <div id="divResult"></div> </body> </html>

The only difference is in the syntax. With append method we first specify the target elements and then the content that we want to append, where as we do the opposite with appendTo method. jquery prepend example : The following example prepends the specified HTML to all div elements <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('div').prepend('<b>Tutorial </b>'); }); </script> </head> <body style="font-family:Arial"> <div id="div1">jQuery</div> <div id="div2">C#</div> <div id="div3">ASP.NET</div> </body> </html> jquery prependTo example : The above example can be rewritten using prependTo as shown below. $('<b>Tutorial </b>').prependTo('div'); What is the difference between prepend and prependTo Both these methods perform the same task. The only difference is in the syntax. With prepend method we first specify the target elements and then the content that we want to prepend, where as we do the opposite with prependTo method. jQuery append existing element example : These methods (append, appendTo, prepend, prependTo) can also select an element on the page and insert it into another <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('div').append($('#mySpan')); }); </script> </head> <body style="font-family:Arial"> <span id="mySpan"> Programming</span> <div id="div1">jQuery</div> <div id="div2">C#</div> <div id="div3">ASP.NET</div> </body> </html> Difference between prepend and append prepend method, inserts the specified content to the beginning of each element in the set of matched elements, where as append method inserts the specified content to the end of each element in the set of matched elements.

What are jQuery DOM manipulation methods 2. How to set attribute values using jQuery attr() method 3. How to retrieve attribute values using jQuery attr() method 4. How to set multiple attribute values using jQuery attr() method 5. How to remove an attribute using jQuery removeAttr() method What are jQuery DOM manipulation methods jQuery DOM manipulation methods manipulate the DOM in some manner. The complete list of jQuery DOM manipulation methods can be found at the following link. http://api.jquery.com/category/manipulation/ jQuery attr method is used to set or retrieve attribute values of html elements. Retrieves the title attribute value of the first matching element $('div').attr('title') Example : In this example we have 2 DIV elements. Since attr() function retrieves only the attribute value of first matching element, we only get the title attribute value of the first DIV element. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { alert($('div').attr('title')); }); </script> </head> <body style="font-family:Arial"> <div id="div1" title="My DIV1"> DIV 1 </div> <div id="div2" title="My DIV2"> DIV 2 </div> </body> </html> To retrieve the title attribute value of all the matching elements, jQuery each() method can be used. <script type="text/javascript"> $(document).ready(function () { $('div').each(function () { alert($(this).attr('title')); }); }); </script> Sets the title attribute value of all the matching elements to "new div title" $('div').attr('title', 'new div title'); Example : If you want to set the same value for the title attribute of all the elements, then there is no need to loop thru each element. All the div elements in this case will have 'new div title' as the title attribute value. <script type="text/javascript"> $(document).ready(function () { // set the same title attribute value for all the DIV elements $('div').attr('title', 'new div title'); // Retrieve and alert the title attribute value of all DIV elements $('div').each(function () { alert($(this).attr('title')); }); }); </script> If you want to set a different value for the title attribute, then you may need to loop thru each element. <script type="text/javascript"> $(document).ready(function () { // sets a different title attribute value for each DIV element $('div').each(function (i) { $(this).attr('title', 'div ' + (i + 1) + ' title'); }); // Retrieve and alert the title attribute value of all DIV elements $('div').each(function () { alert($(this).attr('title')); }); }); </script> How to set multiple attribute values : Using a JSON object to set multiple attribute values <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { var config = { 'title': 'New Div Title', 'style': 'border:3px solid red;', 'name': 'My Div' }; $('div').attr(config); var result = ''; $('div').each(function () { result += 'title = ' + $(this).attr('title') + '<br/>'; result += 'style = ' + $(this).attr('style') + '<br/>'; result += 'name = ' + $(this).attr('name') + '<br/><br/>'; }); $('#resultSpan').html(result); }); </script> </head> <body style="font-family:Arial"> <div id="div1" title="My DIV1"> DIV 1 </div> <br /> <div id="div2" title="My DIV2"> DIV 2 </div> <br /> <span id="resultSpan"> </span> </body> </html> Instead of creating a separate JSON object (config) and then passing it to attr() method, you can create the JSON object inline. $('div').attr({ 'title': 'New Div Title', 'style': 'border:3px solid red;', 'name': 'My Div' });

jquery floating div
 
13:36
Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/05/jquery-floating-div.html In this video we will discuss, how to create floating div using jQuery. We want the div element in the sidebar to be floating and always visible as we scroll down the page. Example : In this example we are using position() and scrollTop() functions. The object returned by position() function has top and left properties, which can be used to know the current top and left positions (coordinates). We are using this function to find the top position of the div element that we want to keep floating as we scroll down. To get the current vertical position of the scroll bar, we are using scrollTop() function. As we scroll and when the current vertical position of the scroll bar becomes GREATER THAN the top position of the div element, then we want the div element to start floating. To do this set position style to fixed. A fixed position element is positioned relative to the browser window. So as you scroll down it will be floating in the browser window. If the current vertical position of the scroll bar becomes LESS THAN the top position of the div element, then we don't want the div element to float, so we set position style to relative. A relative position element is positioned relative to itself. So if you set position to relative and top to 0, it will continue to stay where it is without floating. <html> <head> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { var floatingDiv = $("#divfloating"); var floatingDivPosition = floatingDiv.position(); $(window).scroll(function () { var scrollPosition = $(window).scrollTop(); if (scrollPosition >= floatingDivPosition.top) { floatingDiv.css({ 'position': 'fixed', 'top' : 3 }); } else { floatingDiv.css({ 'position': 'relative', 'top' : 0 }); } }); }); </script> </head> <body style="font-family:Arial;"> <table align="center" border="1" style="border-collapse:collapse"> <tr> <td style="width:500px"> Main Page Content </td> <td style="width:150px; vertical-align:top"> Side panel content <br /><br /> <div id="divfloating" style="background-color:silver; width:150px; height:150px"> Floating Div - Keeps floating as you scroll down the page </div> </td> </tr> </table> </body> </html>

It applies to window objects, but also to scrollable frames and elements with the overflow CSS property set to scroll.

jquery show hide password

Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/05/jquery-show-hide-password.html In this video we will discuss how to toggle password visibility using show / hide password checkbox. Here is what we want to achieve 1. When Show password checkbox IS NOT CHECKED, the password should be masked 2. When Show password checkbox IS CHECKED, the password should be in clear text and visible to the user One of the simplest ways of achieving this is by changing the type attribute of the password field depending on the checked status of Show password checkbox 1. If the Show password checkbox is CHECKED change the type to text 2. If the Show password checkbox is NOT CHECKED change the type to password Replace < with LESSTHAN symbol and > with GREATERTHAN symbol The following is the HTML and jQuery code <html> <head> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#cbShowPassword').click(function () { $('#txtPassword').attr('type', $(this).is(':checked') ? 'text' : 'password'); }); }); </script> </head> <body style="font-family:Arial"> Password : <input type="password" id="txtPassword" /> <input type="checkbox" id="cbShowPassword" />Show password </body> </html> The problem with the above approach is that it does not work in IE 8 and earlier versions. This is because with IE8 and earlier versions the type attribute of input elements cannot be changed once set. The following code works in all browsers including IE8 and earlier versions. When Show password checkbox is clicked 1. Retrieve the value the from the password textbox and store it in a variable for later use. 2. Delete the password input filed. 3. If the "Show password" checkbox is CHECKED, then add a new input filed of type text, else add a new input filed of password. In both the cases set the value attribute of the input element = the variable created in Step 1. <html> <head> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#cbShowPassword').click(function () { var currentPassowrdFiled = $('#txtPassword'); var currentPassword = currentPassowrdFiled.val(); currentPassowrdFiled.remove(); if ($(this).is(':checked')) { $(this).before('<input type="text" id="txtPassword" value="' + currentPassword + '">'); } else { $(this).before('<input type="password" id="txtPassword" value="' + currentPassword + '">'); } }); }); </script> </head> <body style="font-family:Arial"> Password : <input type="password" id="txtPassword" /> <input type="checkbox" id="cbShowPassword" />Show password </body> </html>

jquery tooltip widget
 
08:32
Link for all dot net and sql server video tutorial playlists https://www.youtube.com/user/kudvenkat/playlists?sort=dd&view=1 Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/06/jquery-tooltip-widget.html In this video we will discuss jQuery tooltip widget with examples. To get a tooltip without using jQuery all you do is set the title attribute. At this point when we hover over the element the content that is specified as the value for the title attribute will be displayed as the tooltip. jQuery Tooltip widget replaces native tooltip and allows lot of customization 1. Display other content than just the title, like inline footnotes or extra content retrieved via Ajax. 2. Customize the positioning, e.g., to center the tooltip above elements. 3. Add extra styling to customize the appearance, for warning or error fields. In the following example label element display the native tooltip where as the textbox displays jQuery tooltip HTML <label id="lblName" for="txtName" title="Full Name">Name</label> <input id="txtName" type="text" title="Your full name as it appears in paasport" /> jQuery $('#txtName').tooltip(); In the following example we are calling tooltip() function on the document object, so this will display jQuery tooltip for all the elements that have title attribute $(document).tooltip(); You can also use the content option, to specify the content for tooltip. When both title attribute and content options are specified, the content specified by the content option will override the content specified by the title attribute. HTML <input id="txtName" type="text" title="Your full name as it appears in paasport" /> jQuery $('#txtName').tooltip({ content : '<u>content option</u> tooltip overriding title attribute tooltip' }); content option supports multiple types. string or a function. HTML <input id="txtName" type="text" title="Your full name as it appears in paasport" /> jQuery $(document).ready(function () { $('#txtName').tooltip({ content: toolTipFunction }); function toolTipFunction() { return 'Tooltip from a function'; } }); Set track option to true to make the tooltip follow the mouse HTML <input id="txtName" type="text" title="Your full name as it appears in paasport" /> jQuery $('#txtName').tooltip({ track: true }); show and hide options can be used to animate the showing and hiding of the tooltip. Both of these options support multiple types. For the detailed description please check the following jquery documentation page http://api.jqueryui.com/tooltip In the following example we are using a JavaScript object, to specify the animation duration, effect and delay while the tooltip is being shown and hidden HTML <input id="txtName" type="text" title="Your full name as it appears in paasport" /> jQuery $('#txtName').tooltip({ show : {delay:10, duration:500, effect: 'slideDown'}, hide: { delay: 10, duration: 500, effect: 'slideUp' } });
