GET.js helps to retreive the data passed in a URL query string.
It can be used in a browser or in Node.js
Just download the script and include it in your page, like this:
<script type='text/javascript' src='GET.js'></script>
There is also a minified version:
<script type='text/javascript' src='GET.min.js'></script>
GET.js can also be used in node.js and is available through the npm:
npm install GET.js
If you use GET.js in a Web browser, you can access the data in the query string of the current page through the $_GET array:
console.log(document.location.href); // foo.html?bar=baz&hello=world
console.log($_GET['bar']); // baz
console.log($_GET['hello']); // world
You can also use the parse_query function to parse the query string of another URL:
var url = 'http://foo.bar/?a=1&b=2&c=3';
console.log(parse_query(url)); // {a: 1, b: 2, c: 3}
If you have installed GET.js through the npm, you can use it in node.js like this:
var GETjs = require('GET.js'); // import it first
var url = 'http://foo.bar/?a=1&b=2&c=3';
GETjs.parse_query(url); // {a: 1, b: 2, c: 3} // Use it as in the browser
GET.js is licenced under the BSD 3-clauses license, see the COPYING file for details ...
Have fun !
