Retrieving variable from URL

I can't get this to work. I grabs the variable after the "?" and leaves out any "%" or "2" or "0". There are only 13 department names going to be passed through, so I don't need to wory about #'s.

It did work in FF until I tried to add browser compatability since it has to be IE and FF compliant. I am confused why this does not work. Thanks for your time.


if (document.getElementById)
{var strvar = document.getElementById("url").indexOf('?');}
else
{var strvar = document.url.indexOf('?');}


if (strvar != -1)
{
if (document.getElementById)
{strsearch = document.getElementById("url").substring(strvar+1, document.getElementById("url").length);}
else
{strsearch = document.url.substring(strvar+1, document.url.length);}

for (count = 0; count < strsearch.length; count++)

{

if (strsearch.charAt(count) == "%")
{document.write (" ");}

else if (strsearch.charAt(count) == "2")
{document.write (" ");}

else if (strsearch.charAt(count) == "0")
{document.write (" ");}

else

{document.write (strsearch.charAt(count));}

}
}


else
{document.write("No Department Selected");}

bump. I don't think this is too complicated of a problem for someone how is smarter in DOM's

you're talking javascript here. This is a Java forum, perhaps you would get more responses if you asked in the right forum ;)
