    onmousedown hangs in Mozilla Help!

    Hi,
    I'm trying to make it so when I click a image it prints out the image
    again and a load of other stuff. So far i've got this far.

    <html>
    <head>
    <script language="JavaS cript" type="">
    document.onmous edown = onmousedown;
    function onmousedown(e)
    {
    document.writel n("hello");
    }
    </script>
    </head>
    <body bgcolor="FFFFFF ">

    <img border="1" src="iecadaptor .jpg">

    </body>
    </html>

    but in Mozilla it prints out hello then hangs looking like it's doing
    something then I have to press back. In Explorer it works doesn't hang.
    Any ideas anyone why it's hanging in mozilla(linux)?
    Also if I change the document.writel n("hello"); to

    document.writel n("<img border="1" src="iecadaptor .jpg">");

    it doesn't print out an image just hangs in mozilla. Any ideas?

    Ideally I would like it so document.writel n doesn't have to reload to a
    new page and just uses a layer using <div stuff but that's next.

    Help anyone please

    Thanks

    Gary

      Well it is hanging there waiting for further document.write calls or a
      document.close( ) call.

          Thank you very much the document.close( ) works a treat. Now I can figure
          out the rest.

          Cheers

              Don't do that. The type attribute should be used to specify the scripting
              language, not language (it is deprecated).

              <script type="text/javascript">

              is the correct way to write the tag (with optional src and defer
              attributes).

                  A function cannot be named "onmousedow n" or "onMouseDow n" or anything
                  that is already predefined in Javascript (that would rule out "write",
                  "writeln", "replace", "length", "for", "if", etc..).

                  The quotations need to be "escaped," that is, it needs to be:
                  document.writel n("<img border=\"1\" src=\"iecadapto r.jpg\">");

                  If the quotes were not escaped, then it would be read as "<img
                  border=" only and then an error would come saying something how the
                  string wasn't concatenated properly.

                      Sure it can. "for" and "if" are keywords, and cannot be used for
                      identifiers. The remaining are perfectly good names for functions
                      (although one should be careful when using them, since they can
                      conflict with other uses of the identifier).

                      The following is perfectly legal and works (tested in IE6, Opera 7,
                      Moz FB, and Netscape 4):

                      <script type="text/javascript">
                      function onMouseMove() {
                      return onmousemove();
                      }
                      function onmousemove() {
                      return writeln();
                      }
                      function writeln() {
                      return write();
                      }
                      function write() {
                      return replace();
                      }
                      function replace() {
                      return length();
                      }
                      function length() {
                      return 42;
                      }
                      alert(onMouseMo ve());
                      </script>

                          Nonsense. Firstly, "onMouseDow n" is not defined in any common DOM.
                          Secondly, a user-defined function *should* not have one of the mentioned
                          identifiers (where "for" and "if" make an exception, see below).
                          Depending on the used DOM, it nevertheless can and would thus overwrite
                          the intrinsic method. Sometimes this is desired, e.g., when writing
                          script that blocks popups. Thirdly, no user-defined token, including
                          method identifiers, may be a reserved word, like "for" and "if".

                          No, it needs not to be escaped. Fortunately, ECMAScript
                          and implementations allow <'> for string delimiter:

                          document.writel n('<img border="1" src="iecadaptor .jpg">');

                          Please do not do that, you are wasting precious resources.
