Http GET request in javascript

Question

How can I get JSON from http get request in javascript? The URL is:

    http://www.streamfinder.com/api/?api_codekey=[devkey]&do=get_genre_list&return_data_format=json

I have already tried a lot of stuff, but none of them seem to work... I have tried this, but it is also not working.

function httpGet(theUrl)
{
    var xmlHttp = null;

    xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false );
    xmlHttp.send( null );
    return xmlHttp.responseText;
}

The search keyword you are looking for is "Ajax" (assuming you mean client side JS in a web page) — Quentin

You make an XHR request. There's copious information online describing how to do this. — cookie monster

That's a cross domain call which you can only perform if the remote server allows it which that one does not. Try jsonp. — Alex K.

The problem was that i was using json instead of jsonp. The code that worked is this:

$.ajax({
        url: "URL",
        type: 'GET',
        dataType: 'jsonp',
        success: function(res) {

            alert(JSON.stringify(res));
        }

    });
