    Javascript and Netscape 4.7

    Hello,

    excuse me in advance for my poor english...

    I have a problem with NS 4.7 (I know, it is old, but I have no
    choice...) :

    So, I have a page with a link to open a new window:

    var strHtml = '<html><head><t itle>title_of_w indow</title>' +
    '<LINK rel=stylesheet href=theme.css> '+
    '<SCRIPT LANGUAGE="JavaS cript" SRC="my_script. js"></SCRIPT>' +
    '</HEAD><BODY onLoad="fonc_on Load();" class=Body topmargin=0
    leftmargin=0 MARGINWIDTH=0 MARGINHEIGHT=0> ' +
    'blablabla' +
    '</body></html>';

    var win = window.open('', 'window_name', 'parameters');
    win.document.wr ite(strHtml);
    win.document.cl ose();
    win.focus();


    My problem concerns the tag "onLoad " of the "BODY" tag: with IE, the
    "fonc_onLoa d()" starts normally (this function is in "my_script.js") ,
    but with NS 4.7 (ou 4.51), the <SCRIPT> tag is ignored (you can view the
    window's source code), so the "fonc_onLoa d()" function cannot not start.

    Any help would be highly appreciated.
    Thank you very much in advance.

    Yours sincerely, Thierry

      Try to insert some dummy script e.g.
      strHTML = '<html><head><t itle>...<\/title>'
      + '<script type="text/javascript">var dummy = 1;<\/script>'
      + '...'
      that sometimes helps that NN4 recognizes your script

          The first problem occurs here:
          </SCRIPT>
          will terminate parsing of the javascript block in which this code has
          been written. It needs to be escaped to
          <\/SCRIPT>
          even though it occurs within a quoted string.

          There are two more related problems that I know of:

          a) When writing "<\/SCRIPT>" within generated content, it needs to be
          the last thing written in a single call to document.write. If not, NS4
          can produce layout errors. If necessary, break up strHTML into pieces
          and write them separately. I can not say that this bug will affect your
          page for sure, but the bug certainly exists.


          b) NS4 has trouble loading external javascript files within pages
          generated by pages loaded using the "file://" protocol. Testing this
          page most likely needs to be done using a server.
          (For testing on my local machine, I use Personal Web Server (PWS) under
          Windows 98, or Appache under Windows XP.)


          amicalement,

          Dom

              here, it is not necessary...
