I was wondering if someone could provide some insight to as why when I click on the random form link below it doesn’t randomly load one of the listed forms. It works on jfiddle here:

    The problem is your jquery code runs before any forms exist on the page. At that point, you cannot assign the click event to #randomForm (jQuery will try to, but since #randomForm does not exist yet, it will do nothing).

    Use the document.ready handler:

    <script type="text/javascript">
$(document).ready(function(){
    $('#randomForm').click(function() {
        var forms = $('#forms > form');
        forms.hide();
        forms.eq(Math.floor(Math.random() * forms.length)).show();
    });​
});​
</script>
