Question

I'm trying to get innerHTML of a DIV that is located on external page. It is possible to do this using this kind javascript code?

    <script type="text/javascript">
        $(document).ready(function(){
            var html = document.getElementById("glr1").src='/my_page.html'.innerHTML ;
            alert(html);
        });
    </script>

the jquery load function allows you to specify an element id to load

$('#result').load('ajax/test.html #container');
