What is the easiest way to read/manipulate query string params using javascript?

Question

The examples I've seen online seem much more complex than I expected (manually parsing &/?/= into pairs, using regular expressions, etc). We're using asp.net ajax (don't see anything in their client side reference) and would consider adding jQuery if it would really help.

I would think there is a more elegant solution out there - so far this is the best code I've found but I would love to find something more along the lines of the HttpRequest.QueryString object (asp.net server side). Thanks in advance,

Answer 1

There is indeed a QueryString plugin for jQuery, if you're willing to install the jQuery core and the plugin it could prove useful.

Answer 2

I am using this function in case i don't want to use a plugin:

function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split("&");
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split("=");
        if (pair[0] == variable) {
            return pair[1];
        }
    }
    return null;
}
