Question

Now that i learned how to pass values to an SWF object via flashvars, could you please guide me how can i pass values from a querystring to javascript?

What do i mean? In the following example i hard-code the xml file to load in the SWF object.

<script type="text/javascript">
    var so = new SWFObject("preview.swf", "", "100%", "100%", "9", "#ffffff");
    so.addParam("allowFullScreen", "true");
    so.addParam("scale", "noscale");
    so.addParam("menu", "false");
    so.addVariable("xmlPath", "xml/exampleData.xml");
    so.write("flashcontent");
</script>

Since the Xml file is created dynamic, the xml should be loaded from the value of a query-string. (I guess).

Supposing my url is http://www.example.com/load.aspx?XmlFile=SomeData

How can i pass it to the javascript side? Like..

  so.addVariable("xmlPath", "xml/<% SomeData %>.xml");

or whatever it needs to make it work.

UPDATE: Besides the above example, is there any way of creating the JavaScript, in server-side?

Try something like:

function GetQueryString(param) 
{
 var url = window.location.search.substring(1);
    var params = url.split("&");
    for (i=0;i<params.length;i++) 
    {
        var p = params[i].split("=");
        if (p[0] == param) 
        {
            return p[1];
        }
    }   
}

And use it like:

so.addVariable("xmlPath", "xml/" + GetQueryString("XmlFile") + ".xml");
