jquery modify url get parameters

Question

I got a URL like this:

http://google.de/test.php?a=b&c=d&e=f

I know got to modify just one of the GET params like this: (c is "h" instead of "d")

http://google.de/test.php?a=b&c=h&e=f

and redirect to the new url. All other GET params should stay the same.

How am I going to do this?

Answer 1

You can try something like this:

var changed = "h"; // you can vary this GET parameter

var url = "http://google.de/test.php?a=b&e=f&c=" + changed; // append it to the end

window.location = newurl; // redirect the user to the url

Answer 2

as mentioned window.location.search will give you the query string with ? included.

I would then turn these into an object (perhaps with a library like http://github.com/medialize/URI.js) to make it easier to work with the params. like var params = { key: value, key1: value1}

You could then modify the value you wanted and convert your key value pairs back to a query string.

After this you could use window.location to move the user to next page.
