    Javascript and Mozilla (1.5MacOSX)

    I have looked into creating a javascript that will do a PopUp "Exit Poll" when the client backs out or links forward from the domain. It is a moderated script I found through discussions on this forum.

    Now it works great in MSIE5.2.2 on MacOS10.1.5, but I'm finding I better also make sure it works in Mozilla if I have any chance of making it work on the PC side. When i try it in Mozilla, I get Javascript console saying "loadpopup() is not defined"

    I've found a couple javascripts that work in MSIE but not Mozilla..this is getting irritating to say the least.

    For MacOS10.3 owners using Safari, is the browser compatibility with javascript any better? I feel like I need to get away from MSIE5.2.2 altogether now. And no..I'm not buying a PC.

    HTML Code:
    <script language="JavaScript1.2" type="text/JavaScript1.2">
    That's your problem right there. "text/JavaScript1.2" is not a valid mime-type. Change it to
    HTML Code:
    <script language="JavaScript1.2" type="text/javascript">
    and you're in much better shape.

    The next hurdle you'll have to get over is the fact that recent mozilla versions have a built-in popup blocker, which will merrily supress your popup because it's triggered via an onunload event handler.

    Good eye, blufive

    One more thing, Boss Hoss...

    When assigning an event-handler to element attributes do not use the "javascript:" protocol prefix. This prefix is only for URLs, so only use it when you assign a string of javascript to an HREF attribute, or any place where you would use a URL.
