Pull variable from Query String and add into JS redirect URL

Question

I'm trying to get the value of a variable in the query string example.com/?hop=test

And then pass it to a JavaScript in this form:

var exitsplashpage = 'http://example2.com/?hop=original_hop';

How do I get the original hop variable value using JavaScript and what is the correct format to put it into the exitsplashpage var?

Thanks!

To extract the value, have a look at: http://stackoverflow.com/questions/647259/javascript-query-string — Felix Kling, Apr 14 '11 at 00:03

Using this getQueryString() function from the link that @Felix Kling posted, you would do the following:

var exitsplashpage = 'http://example2.com/?hop=' + getQueryString()["hop"];

Either that, or have a look at jQuery Query String Object, with which you'd do this:

var exitsplashpage = 'http://example2.com/?hop=' + $.query.get("hop");

Try this:

var exitsplashpage = window.location.search.match(/\?hop=([^\&]*)/)[1]

This is unsafe for more than one URL parameter. – Eliasdx Apr 14 '11 at 00:13
I'd use ?|& to allow `?foo=bar&hop=poh&bar=foo`. Also OP is checking against `hop`. But that is kinda obvious. – Eliasdx Apr 14 '11 at 00:19
Calm down, simple mistake on my part. But if you want to go there, I would say it's also kinda obvious that the OP was not asking for `?foo=bar&hop=poh&bar=foo`. – clmarquart Apr 14 '11 at 00:23
Thank you. This worked with a minor modification: `var exitsplashpage = 'http://example2.com/?hop=' + window.location.search.match(/[\?\&]hop=([^\&]*)/)[1];` needed to include the redirect URL and I didn't mention, but the hop variable might not be the first in the query string. – Dustin Apr 14 '11 at 17:30
