location query - passing a variable

[jacq]

i am trying to add an ID to a web page URL.
i have (in ASP) reqID = request.QueryString("ID&quot, and can read this with response.write, but when i try to put this value into my URL is returns nothing:
location = "../folder1/comment.asp?ID=" + reqID;

if i put location = "../folder1/comment.asp?ID=2" it works fine. is it because the variable wasn't created in javascript, and if so, how can i get the ID from the URL in javascript, ie is there a similar function to request.querystring in javascript?

In JavaScript, in order to get the Query, the code is

location.search

What it does is return the question mark, followed by whatever else is behind it. For example, if you tried to access

myPage.html?q=myQuery&msg=hey

, using the

location.search

property would return

?q=myQuery&msg=hey

However, I don't think you would need to do so. If you correctly defined

reqID

, it should work properly with your ASP script.

thanks, i can pick up the ID now, but i still can't get it to pick it up in the URL

reqID = location.search

location = "../folder1/comment.asp+reqID";
returns

http://server1/asps/folder1/comment.asp+reqID

instead of

http://server1/asps/folder1/comment.asp?ID=2

what am i doing wrong?

Hmm... There's a difference between the code you just posted and the code you had posted earlier. But I can tell you, in the code you just posted:

In JavaScript, in order to add a variable's value to a string, you must add it to the end of a string:

location = "../folder1/comment.asp"+reqID;

Keep in mind, too, that for the above code to work correctly, the variable

reqID

must be a String with the contents:

?ID=2

If

reqID

is just a number, you should use this code:

location = "../folder1/comment.asp?ID="+reqID;
