get script text from html

get script text from html

code looks like below:
  1. <script type="text/javascript" src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js'></script>

    <script>
        jQuery(document).ready(function() {
           
            // case 1
            alert('case 1');
            var h = jQuery("<div><script id='t'>var a=1;<\/script><\/div>");
            alert( h.find("#t").text() );
           
            // case 2
            alert('case 2');
            h = jQuery("<script id='t'>var a=1;<\/script>");
            alert( h.find("#t").text() );
    });













under IE, both alert blank.
under FF, the first one alert var a=1; but the second one is blank.
if change 1.3.2 to 1.4.2, all are blank.

so my question is:
how to get script text from a HTML code piece (which is from ajax)?

Thanks a lot
