public class JavaScriptButton
extends PushButton

The JavaScriptButton class is derived from the PushButton class.

This class will execute a supplied client side script when pressed.

If no script is provided, then this component acts exactly likes its base PushButton class.

This component is useful for "running" any abitary client side scipt. For example you could show an alert dialog "alert('What the story?')" or even open disconnected client window "window.open('http://echopoint.sf.net')"

The script code itself is wrapped in a function, then this function is executed. Therefore any javascript you provide must have "function scope".

Dont forget the quote the script if appropriate, using echopoint.util.QuoterKit
