previous next AddThis Social Bookmark Button


Advertisements

Description:

This option is used to define the effect to use when the draggable starts being dragged.

By default, it changes element's opacity to 0.2 in 0.2 seconds.

Syntax:

new Draggable('element', {starteffect: 'effectFunction'});

Here effectFunction is function which defines effect to be applied.

Example:

<html>
<head>
<title>Draggables Elements</title>
<script type="text/javascript" 
        src="/javascript/prototype.js"></script>
<script type="text/javascript"
        src="/javascript/scriptaculous.js"></script>

<script type="text/javascript">

window.onload = function() {
   new Draggable('myimage', 
                {starteffect: effectFunction('myimage')});
}

function effectFunction(element)
{
   new Effect.Opacity(element, {from:0, to:1.0, duration:10});
}

</script>

</head>
<body>

<p>This image will display very slow in the start.</p>

<img id="myimage" src="/images/scriptaculous.gif"/>

</body>

To understand it in better way you can Try it yourself.
