[Javascript] form parameters

[Chuck Soper]

Hello,

In my desktop application I allow users submit feedback via a web 
page with a form. I do this by launching the default browser, with a 
certain URL. My JavaScript question is: how can I send parameters to 
the form page?

Is it something like this:
   www.mywebsite.com/feedback.html?parm1=productName

How would I access the value of parm1 from JavaScript?

Also, is there a way to pass two parameters?

thanks,
Chuck
