Attach a Squish effect

The Squish effect makes the target element disappear into the upper-left corner of the page. The Squish effect produces the same effect as the Grow effect when the Grow effect’s growCenter option is set to false.

You can only attach this effect to the following HTML elements: address, dd, div, dl, dt, form, img, p, ol, ul, applet, center, dir, menu, or pre.

  1. To link the SpryEffects.js file on your web page, add the following code to the head of your document: 
    <head>
. . .
<script  src="../includes/SpryEffects.js" type="text/javascript" ></script>
</head>
    Note: The exact file path differs, depending on where you store the SpryEffects.js file.

    The SpryEffects.js file is in the includes folder of the Spry folder that you downloaded from Adobe Labs. See Prepare your files.

  2. Make sure your target element has a unique ID. The target element is the element that changes when the user interacts with the page to cause the effect. 
    <div id="squish1"><p>Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliqt</p></div>
  3. To create the effect, add a JavaScript event to trigger the effect, and a script tag that creates the effect object. For example, if you want the user to click on a sentence that causes another paragraph to squish, you might add the following event and script tag: 
    <p><a onclick="squish_effect.start(); return false;" href="#">Click here to squish the paragraph.</a></p>
. . . 
<script type="text/javascript">
var squish_effect = new Spry.Effect.Squish("squish1");
</script>
    Note: It’s important that you add the script tag after the code for the target element. Otherwise the page will return a JavaScript error when you try to trigger the effect.

    The first argument of the Spry.Effect.Squish method is always the target element’s ID ('squish1' in the preceding example).

    The complete code looks as follows:

    <head>
. . .
<script src="../includes/SpryEffects.js" type="text/javascript"></script>
</head>
<body>
<p><a onclick="squish_effect.start(); return false;" href="#">Click here to squish the paragraph.</a></p>
<div id="squish1"><p>Lorem ipsum dolor sit amet, consetetur 
sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut 
labore et dolore magna aliqt</p></div>
<script type="text/javascript">
var squish_effect = new Spry.Effect.Squish("squish1");
</script>
</body>
