How to get Domain name from URL using jquery..?

I have domain name for eq.

1) http://www.abc.com/search 
2) http://go.abc.com/work

I get only domain name from the above URL

Output like

1) http://www.abc.com/
2) http://go.abc.com/

how can I do?

In a browser

You can leverage the browser's URL parser using an <a> element:

var hostname = $('<a>').prop('href', url).prop('hostname');

or without jQuery:

var a = document.createElement('a');
a.href = url;
var hostname = a.hostname;

(This trick is particularly useful for resolving paths relative to the current page.)

Outside of a browser (and probably more efficiently):

Use the following function:

function get_hostname(url) {
    var m = url.match(/^http:\/\/[^/]+/);
    return m ? m[0] : null;
}

Use it like this:

get_hostname("http://example.com/path");

This will return http://example.com/ as in your example output.

Hostname of the current page

If you are only trying the get the hostname of the current page, use document.location.hostname.

This worked for me.

$(location).attr('host');                        www.test.com:8082
$(location).attr('hostname');                    www.test.com
$(location).attr('port');                        8082
$(location).attr('protocol');                    http:
$(location).attr('pathname');                    index.php
$(location).attr('href');                        http://www.test.com:8082/index.php#tab2
$(location).attr('hash');                       #tab2
$(location).attr('search');                     ?foo=123
