Query String ( Get String )

talk open source

Lately I’ve been sick of the fact that I can’t query the get string, dont’ know how many other people are having this issue, in any case I wrote a class that doesn’t require you to have any javascript in the html, and it’s really simple to use, so here it is if you guys wanna improve it feel free, I’ll do what I can when I get the time. Which isn’t often.

   // we will build the function in flash and call it
