Q.  How do you ensure the <div> required by jQuery dialog is here?

A.  I use this function:

function prepDialogDiv(id) { if ($('#'+id).size() == 0) { $('body').append('<div id='+id+'></div>'); } }
Besides ensureing that the <div> is there this also means I don't have to put the <div> into the html page which seems clean to me.
