The onclick event activates when an element is clicked with the mouse.  The event can be specified as a JavaScript expression or the name of a JavaScript function.  

If an expression is used, the JavaScript keyword this refers to the element that was clicked.  

If the name of a function is used, the function will receive 2 parameters when called: 

  • The browser event object

  • A reference to the element that was clicked

Examples:

The following can be placed on an icon which will toggle a Grid's expanded vs. collapsed mode.

onclick: getObj("Grid1").toggle();

The following can be placed on a hyperlink to make it go to a specific URL in a new browser window.

onclick: window.open("http://www.google.com");



Note: By default, a button's "onclick" event will take precedence over the "response" property. If both are defined, the "onclick" event will fire and control will not return to the server.
