YUI and vB SESSIONURL question

[JamesAB]

I've been doing a bit more digging and it seems that the POST vars have to be in the form of an object. They can be inline as I had them, or declared earlier. Unfortunately, you can't use a standard string with all the POST information combined here.

My problem is still that I can't use SESSIONURL + 'securitytoken' as the name of variable, since I'm ultimately trying to POST:

SESSIONURL + 'securitytoken=' + SECURITYTOKEN

The following code is sending vbsessionurlsecuritytoken as the name of the POST variable, not the value of vbsessionurlsecuritytoken.

// THIS DOES NOT WORK
var vbsessionurlsecuritytoken = "securitytoken";
uploader.upload(fileID, "http://tforum.mydomain.com/uploadzip.php", 
                "POST", 
                {"do":"doupload", 
		"albumid":jababumid, 
		"jabuniquezip":jabuniquezip,
		vbsessionurlsecuritytoken:SECURITYTOKEN}, 
		"upload");

Is it even possible in javascript to create an object where the name of the variable is dynamic?

Thanks,
James
