JQuery 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.
Following is the simple syntax for hide() method:
[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 title</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.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 SQUAR </div> <input id="hide" type="button" value="Hide" /> <input id="show" type="button" value="Show" /> </body> </html> |
To understand it in better way you can Try it yourself.
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 title</title> <script type="text/javascript" src="/jquery/jquery-1.3.2.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> </body> </html> |

JQuery Effect Methods:
You have seen basic concept of jQuery Effects. Following table lists down all the important methods to create different kind of effects:
Methods and Description |
---|
animate( params, [duration, easing, callback] ) A function for making custom animations. |
fadeIn( speed, [callback] ) Fade in all matched elements by adjusting their opacity and firing an optional callback after completion. |
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. |
fadeTo( speed, opacity, callback ) Fade the opacity of all matched elements to a specified opacity and firing an optional callback after completion. |
hide( ) Hides each of the set of matched elements if they are shown. |
hide( speed, [callback] ) Hide all matched elements using a graceful animation and firing an optional callback after completion. |
show( ) Displays each of the set of matched elements if they are hidden. |
show( speed, [callback] ) Show all matched elements using a graceful animation and firing an optional callback after completion. |
slideDown( speed, [callback] ) Reveal all matched elements by adjusting their height and firing an optional callback after completion. |
slideToggle( speed, [callback] ) Toggle the visibility of all matched elements by adjusting their height and firing an optional callback after completion. |
slideUp( speed, [callback] ) Hide all matched elements by adjusting their height and firing an optional callback after completion. |
stop( [clearQueue, gotoEnd ]) Stops all the currently running animations on all the specified elements. |
toggle( ) Toggle displaying each of the set of matched elements. |
toggle( speed, [callback] ) Toggle displaying each of the set of matched elements using a graceful animation and firing an optional callback after completion. |
toggle( switch ) Toggle displaying each of the set of matched elements based upon the switch (true shows all elements, false hides all elements). |
jQuery.fx.off Globally disable all animations. |
UI Library Based Effects:
To use these effects you would have to download jQuery UI Library jquery-ui-1.7.2.custom.min.js or latest version of this UI library from jQuery UI Library.
After extracting jquery-ui-1.7.2.custom.min.js file from the download, you would include this file in similar way as you include core jQuery Library file.
