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.
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.
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.
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>
|
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.
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.
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>

| 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. |

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.
