Passing query string through a page

[elcaro2k]

Can someone tell me the best way to pass a query string through an intermediate page on to the next page? In other words I call a page with a query string in the url and at that point I call another page and I would like to keep the string in tact and pass it to the next page.

Thanks,
Ray

Hi,
If Your location is: http://blah.com/page1.html?x=12

newPage = http://blah.com/page2.html;
newURL = newPage + '?' + document.location.search;

should produce http://blah.com/page2.html?x=12 (or something similar - too lazy to check the exact syntax right now)...

You could parse the intermediate page location, and get the query string, then append it to the link to the last page.

parse.html

<script type="text/javascript" language="JavaScript">
function getString(){
var str = new String(document.location);
vars = str.split("?");
if (vars.length == 2)
return "?"+vars[1];
else //
return "";
}
</script>
<script type="text/javascript" language="JavaScript">
document.writeln("<a href='http://www.yahoo.com/"+getString()+"'>Next Page</a>");
</script>
<br><a href="parse.html?me=mine&amp;isnot=here">Here</a>


That should give you some idea. I just put there Here link to give it something to parse. It would work just as well if it were coming to parse.html.

Alex Close. First off, location is a sub-object to window not document. 2nd, location.search already includes the '?', so it needs not appending here.

newURL = newPage + location.search;

OK, I am confused. If I do a document.write(location.search) I get nothing, however, if I use vbScript and do a response.write(Request.Form()), I print out the query string? Why can I not see it in JS?

btw, the reason I was printing it out is because the target page was not receiving the string.

The above assumes a form method GET, not a POST, if it is a post, you will have to have the server pass back the information posted.
