jQuery $(document).ready and UpdatePanels?

Question

I'm using jQuery to wire up some mouseover effects on elements that are inside an UpdatePanel. The events are bound in $(document).ready . For example:

$(function() {    
    $('div._Foo').bind("mouseover", function(e) {
        // Do something exciting
    });    
});

Of course, this works fine the first time the page is loaded, but when the UpdatePanel does a partial page update, it's not run and the mouseover effects don't work any more inside the UpdatePanel.

What's the recommended approach for wiring stuff up in jQuery not only on the first page load, but every time an UpdatePanel fires a partial page update? Should I be using the ASP.NET ajax lifecycle instead of $(document).ready?

You could also try:

<asp:UpdatePanel runat="server" ID="myUpdatePanel">
    <ContentTemplate>

        <script type="text/javascript" language="javascript">
        function pageLoad() {
           $('div._Foo').bind("mouseover", function(e) {
               // Do something exciting
           });
        }
        </script>

    </ContentTemplate>
</asp:UpdatePanel>

,since pageLoad() is an ASP.NET ajax event which is executed each time the page is loaded at client side.
