Get the query string(s)

readme.md

Usage

// index.html?keywords=test

qs(); // { name: 'keywords', values: [ 'test' ] }

But wait, why store the value in an array?

Because of

// index.html?category=4&category=5&category=6

qs(); // { name: 'category', values: [ '4', '5', '6' ] }

which is a perfectly valid use of query strings.

Also

qs('category'); // [ '4', '5', '6' ] 

qs.js

function qs() {

var vars = [],
		grabUrl = window.location.search,
		parts,
		pieces,
		qs = '',
		qsVals = [];

	if (typeof arguments[0] == 'string') {
		qs = arguments[0];
	}

	if (typeof grabUrl != 'undefined') {

		grabUrl = grabUrl.replace("?", '');
		parts = grabUrl.split("&");

		for (var j in parts) {

			pieces = parts[j].split('=');

			if (vars.length != 0) {
				for (var i in vars) {
					if (vars[i].name == pieces[0].toString()) {
						vars[i].values.push(pieces[1]);
					} else {
						vars.push({ "name" : pieces[0].toString(), "values" : [pieces[1]] });
					}
				}
			} else {
				vars.push({ "name" : pieces[0].toString(), "values" : [pieces[1]] });
			}

		}

		if (qs != '') {
			for (var i in vars) {
				if (vars[i].name == qs) {
					return vars[i].values;
				}
			}
		}
		
		return vars;

	} else {

		return [];

	}
