Get query parameters

gistfile1.js

function getParams() {
	var parameters = location.search.substring(1).split('&'); // drop initial '?' and get array of 'key=value'
	var obj = {};
		
	for(var i=0; i < parameters.length; ++i){
		// 0 with the key, 1 with the value
		var keyvalue = parameters[i].split('=');
		
		// this won't work well when we try to pass jsons as parameters. 
		obj[ decodeURIComponent(keyvalue[0]) ] = decodeURIComponent(keyvalue[1]);
	}
	return obj;
}
