    [beginer]Why this script failed to work?

    HI:

    I paste my script below:

    <html>
    <head>
    <script src="http://code.activestat e.com/js/jquery-1.2.1.js"
    type="text/javascript"></script>

    <script language="javas cript" type="text/javascript">
    function onLoad() {
    var frame1 = $("#frame1");
    alert("1");
    var innerDoc = (frame1.get(0). contentDocument ) ?
    frame1.get(0).c ontentDocument : frame1.get(0).c ontentWindow.do cument;
    alert("2");
    var b=innerDoc.body ;
    alert("3");
    alert(innerDoc. body.scrollHeig ht);
    }
    </script>

    </head>
    <body>
    <iframe id="frame1" src="http://www.baidu.com" width=100%
    onload="onLoad( )">
    </body>
    </html>

    The script only alert "1" in IE and alert "2" in firefox. It seems
    stop execute after then.

    Does any guy know why?

          Why the # character in there? Maybe it's a prototype.js syntax thing, I
          don't know.
          alert("1");
          var innerDoc = (frame1.get(0). contentDocument ) ?
          You're not checking first if frame1 != null, which it would be if that #
          above was wrong. You're also trying to access the contentDocument of a
          page in a different domain. This is actively blocked by the browsers for
          security reasons.
          frame1.get(0).c ontentDocument : frame1.get(0).c ontentWindow.do cument;
          alert("2");
          var b=innerDoc.body ;
          alert("3");
          alert(innerDoc. body.scrollHeig ht);
          }

              But by using firebug, I can view the innerDoc 's content and other
              attributes in the debug window.

                  That looks like something from jQuery, so ask in a jQuery forum.
