Get and javascript? like php's if $_GET[foo]

Question

I am coding a javascript http web server node, for a CDN project, I am used to PHP's

if ($_GET = "hello"); echo "Yey!"

but have no idea how to do so, I am new to javascript.

Is this a duplicate of your earlier question: http://stackoverflow.com/questions/34559227/javascript-variables-for-get-http? — Colin Brock, Jan 03 '16 at 01:18
the earlier question was answered, but the answer was off topic, the code I was given was for a node.JS web server. — alex tix, Jan 03 '16 at 13:37

NodeJS

var url = require('url');
var url_parts = url.parse(request.url, true);
var query = url_parts.query;

Without NodeJS:
Use URI.js to get the query string. https://medialize.github.io/URI.js/

var uri = URI("urn:uuid:c5542ab6-3d96-403e-8e6b-b8bb52f48d9a?hello=world");
uri.protocol() == "urn";
uri.path() == "uuid:c5542ab6-3d96-403e-8e6b-b8bb52f48d9a";
uri.query() == "hello=world";

You can Try this functions:

function httpGet(theUrl)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false ); // false for synchronous request
    xmlHttp.send( null );
    return xmlHttp.responseText;
}

However, synchronous requests are discouraged, so you might want to use this instead:

function httpGetAsync(theUrl, callback)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.onreadystatechange = function() { 
        if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
            callback(xmlHttp.responseText);
    }
    xmlHttp.open("GET", theUrl, true); // true for asynchronous 
    xmlHttp.send(null);
}

Notes: Starting with Gecko 30.0 (Firefox 30.0 / Thunderbird 30.0 / SeaMonkey 2.27), synchronous requests on the main thread have been deprecated due to the negative effects to the user experience.

How would I do a simple variable comparison? like === – alex tix Jan 03 '16 at 13:36 — alex tix, Jan 03 '16 at 13:36
in javascript i think it is like this == or === – The Beast Jan 03 '16 at 15:30 — The Beast, Jan 03 '16 at 15:30
