Convert From ASP to Javascript

[Krus1972]

Hello,

I am an ASP programmer and know only a little Javascript. Can someone convert the following ASP code to Javascript? Basically the script requests the variable "q" from the query string and if its = "" then the browser redirects to a URL that is specified.


<% If request ("q") = "" Then
response.redirect ("

http://URLHERE.COM")

End If
%>

Thank you for any help

Hi

You can not. The [tt]response.redirect[/tt] returns HTTP 302 response code. Client-side scripting languages can not set it.

The closest JavaScript alternative would be this :

if (location.search.match(/(^|[?&;])q=([&;]|$)/)) location.href='[URL unfurl="true"]http://example.com/'[/URL]

Hello,

I don't care about the 302 response code. The only thing need the javascript to do is:

1. Request "q" from the querystring
2. Check to see if it's empty
3. Then send the visiotr to another URL that I specify in the script.

I don't care about the 302.

Thanks for any help.

Can you post an example URL from the browser address bar and also do a Response.Write(q) when (q = "") and when q <> "" and then post the two results?

Hi

How would that help you, vbdewd ?

feherke,
First, I'm wondering why Krus1972 doesn't use asp to do the redirect (if it's an asp page).

How would it help me? I'd look at the result and see if I could come up with an alternate route besides what you posted using a combo of asp and js.

Hi

So you are thinking to alternative. That explains your question.

But as you pointed out, "if it's an asp page". The OP should answer that first.
