script.aculo.us - Toggle Effects Utility


Advertisements


Description

The Effect.toggle allows you to toggle between hide and show, slide up and slide down, and blind up and blind down.

For example, it checks if the element is in hide state, then it will show that element.

This utility function is most useful in scripts where the current state of the element is unknown or moot, and toggling the element to the opposite state is all that matters.

Syntax

Use the following syntax for this effect −

Effect.toggle( element, [effectType], [options] );

Where effectType is one of the strings −

  • If effectType is set to appear, the Fade and Appear effects are used to toggle the element into and out of visibility.

  • If effectType is set to slide, the SlideUp and SlideDown effect are used.

  • If effectType is set to blind, the BlindUp and BlindDown effect are used.

If the effectType is omitted, the default is appear
