    HTML comments within JavaScript - Netscape documentation ??

    Hi there

    About this business of embedding HTML comments in Javascript.

    Everyone tells me that JavaScript parsing ignores any line starting
    with <!--
    but that I need to protect any occurrence of --> with a Javascript
    comment //.

    My browser (IE 6) seems to handle <!-- as described, but also seems
    to ignore occurrences of -->, with or without a leading //.

    I was trying to look up the official ruling on this in the
    JavaScript 1.5 Guide and Reference on Netscape, but I can't seem to
    find any mention of it in the various Netscape documents. So is this
    an undocumented convention which JavaScript compliant browsers can
    choose to handle just as they like ?

    thanks

    - griff

      They are not even close to being in use. The script tag, and the HTML
      comment convetion, was introduced with the transition from Netscape 1
      to Netscape 2. The release of Netscape 2.0 was March 1996. Netscape 2
      works fine without the HTML comments.

      IE supported scripts from v3.0(beta1) in May 1996.

      The script tag was then introduced into HTML 3.2, which was made a
      recommendation in 1997.

          Yep you are right. I will have to switch to saying "The browsers that
          were new when it was introduced are not even still in use.".

          (Though I did recently discover that Sheffield university is still
          running some machines with Window 3.1 installed, but I doubt that anyone
          does much web browsing from them.)

          Richard.

              Also if you're the sort of person who follows such cargo-cults, you
              may be the sort of person to jump on the XHTML bandwagon, and for
              XHTML the browser is free to chuck away everything inside a comment,
              so your script could simply disappear.

              Jim.
