ImageButton

(extends Object)

Object Summary

This object models a button which has an on-off (or 1-0) state, which makes it possible to programatically switch it via client-side scripting.

 

ImageButton can be used to represent two-state events

(like system is working/system is down, valid action/invalid action, stop/go etc).

Constructor

 

ImageButton(elmID,strOnURL,strOffURL,intCurrentState)

 

parameters

elmID - The object reference or String index of the DHTML element.

strOnURL - The URL of the on image (when state is 1).

strOffURL - The URL of the off image (when state is 0).

intCurrentState - The initial state of the object.
