jQuery Forum

I'm trying to use jQuery inside a CMS which use mootools - therefore I
use noConflict.
I have this sample code:
    jQuery.noConflict();
    (function($) {
        function doSomething() {
            //some jQuery Stuff here..
            alert("something");
        }
    })(jQuery)
    jQuery(document).ready(function() {
        doSomething();
    });
I would like to call the function doSomething() when my DOM is ready.
Why can't I? I also like to call the function as a JavaScript method
in my HTML.
