- Visual Effects


The effects are divided into two groups −

Core Effects

The following six core effects are the foundation of the Visual Effects JavaScript library.

All the core effects support various common parameters as well as effect-specific parameters and these effect names are case-sensitive.

All the effect-specific Common Parameters have been discussed in this tutorial along with the effects.

Combination Effects

All the combination effects are based on the five Core Effects, and are thought of as examples to allow you to write your own effects.

Usually these effects rely on the parallel, synchronized execution of other effects. Such an execution is readily available, hence creating your own combined effects is very easy. Here is a list of Combination Effects −

Additionally, there's the Effect.toggle utility method for elements you want to show temporarily with an Appear/Fade, Slide or Blind animation.

Library Files Required for Effects

To use the effect capabilities of, you will need to load the effects module. So, your minimum loading for will look like this:

      <title> effects</title>
      <script type = "text/javascript"  src = "/javascript/prototype.js"></script>
      <script type = "text/javascript"  src = "/javascript/"effects.j"></script>

Call Effect Functions

The proper way to start a core effect is usually with the new operator. Depending on your preferences, you can use one of two syntaxes −


new Effect.EffectName(element [, requiredArgs ] [ , options ] )
element.visualEffect('EffectName' [, requiredArgs ] [,options])

These two syntaxes are technically equivalent. Choosing between the two is mostly about your personal sense of code aesthetics.


Here are two equivalent calls, so you can see how the syntaxes are related, which are very much interchangeable −

new Effect.Scale('title', 200, { scaleY: false, scaleContent: false });
$('title' ).visualEffect('Scale', 200, { scaleY:false, scaleContent:false });
