If my web page is referenced in the address bar, how can I read these
arguements?
Thus, with
http://www.mydomain.com/mypage.html?abc=123
Is there an easy method to read abc=123 ?
You need to look in: location.search
You may want to escape the passed data. This is commonly done.
This html file and associated Javascript passed data to a second htmls
