jQuery provides a trivially simple interface for doing various kind of amazing effects. jQuery methods allow us to quickly apply commonly used effects with a minimum configuration.
This tutorial covers all the important jQuery methods to create visual effects.
We have used Google CDN for jQuery UI using following code snippet in the HTML page so we can use jQuery UI −
This tutorial covers all the important jQuery methods to create visual effects.
Showing and Hiding elements
The commands for showing and hiding elements are pretty much what we would expect − show() to show the elements in a wrapped set and hide() to hide them.Syntax
Here is the simple syntax for show() method −[selector].show( speed, [callback] );Here is the description of all the parameters −
- speed − A string representing one of the three predefined speeds ("slow", "normal", or "fast") or the number of milliseconds to run the animation (e.g. 1000).
- callback − This optional parameter represents a function to be executed whenever the animation completes; executes once for each element animated against.
[selector].hide( speed, [callback] );Here is the description of all the parameters −
- speed − A string representing one of the three predefined speeds ("slow", "normal", or "fast") or the number of milliseconds to run the animation (e.g. 1000).
- callback − This optional parameter represents a function to be executed whenever the animation completes; executes once for each element animated against.
Example
Consider the following HTML file with a small JQuery coding −<html> <head> <title>The jQuery Example</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("#show").click(function () { $(".mydiv").show( 1000 ); }); $("#hide").click(function () { $(".mydiv").hide( 1000 ); }); }); </script> <style> .mydiv{ margin:10px;padding:12px; border:2px solid #666; width:100px; height:100px;} </style> </head> <body> <div class="mydiv"> This is a SQUARE </div> <input id="hide" type="button" value="Hide" /> <input id="show" type="button" value="Show" /> </body> </html>
Toggling the elements
jQuery provides methods to toggle the display state of elements between revealed or hidden. If the element is initially displayed, it will be hidden; if hidden, it will be shown.Syntax
Here is the simple syntax for one of the toggle() methods −[selector]..toggle([speed][, callback]);Here is the description of all the parameters −
- speed − A string representing one of the three predefined speeds ("slow", "normal", or "fast") or the number of milliseconds to run the animation (e.g. 1000).
- callback − This optional parameter represents a function to be executed whenever the animation completes; executes once for each element animated against.
Example
We can animate any element, such as a simple <div> containing an image −<html> <head> <title>The jQuery Example</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function() { $(".clickme").click(function(event){ $(".target").toggle('slow', function(){ $(".log").text('Transition Complete'); }); }); }); </script> <style> .clickme{ margin:10px;padding:12px; border:2px solid #666; width:100px; height:50px;} </style> </head> <body> <div class="content"> <div class="clickme">Click Me</div> <div class="target"> <img src="./images/jquery.jpg" alt="jQuery" /> </div> <div class="log"></div> </div> </body> </html>

| 3 | fadeOut( speed, [callback] )
Fade out all matched elements by adjusting their opacity to 0, then setting display to "none" and firing an optional callback after completion. |
| 4 | fadeTo( speed, opacity, callback )
Fade the opacity of all matched elements to a specified opacity and firing an optional callback after completion. |
| 5 | hide( )
Hides each of the set of matched elements if they are shown. |
| 6 | hide( speed, [callback] )
Hide all matched elements using a graceful animation and firing an optional callback after completion. |
| 7 | show( )
Displays each of the set of matched elements if they are hidden. |
| 8 | show( speed, [callback] )
Show all matched elements using a graceful animation and firing an optional callback after completion. |
| 10 | slideDown( speed, [callback] )
Reveal all matched elements by adjusting their height and firing an optional callback after completion. |
| 11 | slideToggle( speed, [callback] )
Toggle the visibility of all matched elements by adjusting their height and firing an optional callback after completion. |
| 12 | slideUp( speed, [callback] )
Hide all matched elements by adjusting their height and firing an optional callback after completion. |
| 13 | stop( [clearQueue, gotoEnd ])
Stops all the currently running animations on all the specified elements. |
| 14 | toggle( )
Toggle displaying each of the set of matched elements. |
| 15 | toggle( speed, [callback] )
Toggle displaying each of the set of matched elements using a graceful animation and firing an optional callback after completion. |
| 16 | toggle( switch )
Toggle displaying each of the set of matched elements based upon the switch (true shows all elements, false hides all elements). |
| 17 | jQuery.fx.off
Globally disable all animations. |
UI Library Based Effects
To use these effects you can either download latest jQuery UI Library jquery-ui-1.11.4.custom.zip from jQuery UI Library or use Google CDN to use it in the similar way as we have done for jQuery.We have used Google CDN for jQuery UI using following code snippet in the HTML page so we can use jQuery UI −
<head> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.3/jquery-ui.min.js"></script> </head>
