i need to simulated having clicked on a link with JavaScript. As you will see in my stripped down example the resulting function from the click is a window.addEvent() action. Thanks for the help.

js code -

window.addEvent('domready', function() {
     expandCollapse();
}

function expandCollapse(){
     $('expand').addEvent('click', function(){
          // do something
     }
}

html code -

<a id="expand" href="javascript:void(0);">open all</a>

i have tried this but id didnt work -

document.getElementById('expand').click();

What is the code to make the window.addEvent() fire? *expand* must be part of it. Thank you.

Embarrassingly enough, I have no idea how to do this with regular JavaScript. It is easy to do if you learn the jQuery library, however:

$("#expand").trigger("click");

i use mootools extensively on this site and JQ and MT dont jive together. thanks though.

Thanks to Fang -

Working Solution -

function fireOnclick(objID) {
var target=document.getElementById(objID);
if(document.dispatchEvent) { // W3C
    var oEvent = document.createEvent( "MouseEvents" );
    oEvent.initMouseEvent("click", true, true,window, 1, 1, 1, 1, 1, false, false, false, false, 0, target);
    target.dispatchEvent( oEvent );
    }
else if(document.fireEvent) { // IE
    target.fireEvent("onclick");
    }    
}

Yes they do (jive together), all you do is noconflict the jQuery. Having two libraries together is pretty retarded, I must say, however, unless there is some type of extensive application, such as a site contained within a CMS, that makes two libraries more realistic.

There are a couple ways to do it, but the way I noconflict jQuery is like this:

(function($) {
//a bunch of code goes here, and you may use the $ object instead of jQuery
)(jQuery);

Of course, for such a small amount of code, you may just use jQuery instead of $, like this:

jQuery("#expand").trigger("click");

Of course, as I mentioned, two libraries for an average site is borderline retarded. Are you sure MooTools doesn't have a function for triggering clicks? I know YUI does, and most libraries should have some means of doing it, since it is a common debugging device.

Glad you solved it (looks like we were posting at the same time)...
