Javascript: split and replace url

Question

http://127.0.0.1:8890/demo1/?search=hello%2Cbuddy&Agg=Target+-+All

How do I split the above url and fetch 'search=hello%2Cbuddy' and replace the url as http://127.0.0.1:8890/demo1/?search=goodbye&Agg=Target+-+All

Using javascript I've only reached this far;

var get_url = window.location.href
var parts = get_url.split('/') # doesn't make sense

What exactly did not work for you referencing http://stackoverflow.com/questions/5413899/search-and-replace-specific-query-string-parameter-value-in-javascript or http://stackoverflow.com/questions/2801970/replacing-strings-with-regex-in-javascript ? — Christopher Will, Mar 17 '14 at 14:35
@AmitGarg I guess the actual searchstring is unknown so a direct replacement would not work here — nils, Mar 17 '14 at 15:02

In your case you can replace this part with a simple regular expression:

var url          = document.location.href,
    modified_url = url.replace(/\?search=[^&]+/g, 'search=YOUR_SEARCH_REPLACEMENT');

Replace YOUR_SEARCH_REPLACEMENT with whatever you need there.

I think this function may be best for you?

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

You could use jQuery URL plugin if you're familiar with jQuery.

First, you need to get the Query String, which this post covers: How can I get query string values in JavaScript?

Then you just need to update the url by changing location.href to whatever you want the URL to be.
