    Dynamically changing flash vars

    Is it possible to do so?


    My situation ..
    I have a flash header on my website with 5 menu items (home, register, about us, etc)

    myheader.swf?button=1 "Home" is focused
    myheader.swf?button=2 "register" is focused
    etc etc

    When you click on a menu item it becomes the focused menu item (or "button") and the flash fires off a javascript event which handles the AJAX.

    Using the browser's back/forward buttons, the flash header's focused item does not change.

    I can capture the history change, but how can I change the " .swf?button=x " using javascript.

    PS: the flash header is a big file and I do not want to reload it every single time to update the var

    well that would require some work to narrow down, there's alot of code.

    is there no solution to my problem?

    using javascript to change a flash variable (in this case, "button") to a new value (1,2,3,4,5) to visually change the focused menu item.

    I only wanted to see the flash header and how it receives the parameters. Think you can make an example for us to see?

    I have never worked with changing flash vars on the go. Most I have done is called JavScript function from a flash.

    in the <body> tag of the html..

    <object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="766" height="160">
    <param name="movie" value="_flash/header_v8.swf?button=1"/>
    <param name="FlashVars" value="button=2">
    <param name="quality" value="high" />
    <param name="menu" value="false" />
    <param name="wmode" value="transparent" />
    <!--[if !IE]> <-->
    <object data="_flash/header_v8.swf?button=1"
    width="766" height="160" type="application/x-shockwave-flash">
    <param name="quality" value="high" />
    <param name="menu" value="false" />
    <param name="wmode" value="transparent" />
    <param name="pluginurl" value="http://www.macromedia.com/go/getflashplayer" />
    Flash is not supported on your browser.
    </object><!--> <![endif]-->
    </object>


    I also know that when any menu item receives a click, the flash automatically makes that item the new focused one.

    Is it possible to send a function to the swf that would change which menu item (or "button") is focused?

    Now that I think about it I do not think it would work by just modifying the object flash var. I am not adept at flash, but for the effect to change place inside the flash you would need to have it read the change.

    As far as I know (emphasis) flash will not dynamically change when you change the flash var.

    So, I believe you have to make it so the flash can read some value from somewhere or receive input from JavaScript.

    I believe you are correct, but I'm basing that off of 2 hours of research.

    I will look into alternatives, hopefully I find some workaround.

    Thanks for your help.
