Details on HTTP request object

I am using this code in a slightly modified version.

function parseUrl(url) {
	var idx = url.indexOf("?");
	var data = {
		path:"",
		param:{}
	};
	
	if (idx >= 0) {
		var args = url.substr(idx + 1).split("&");
		
		for (var n in args) {
			var arg = args[n];
			var eq = arg.indexOf("=");
			
			if (eq < 0) {
				eq = arg.length;
			}
			
			data.param[arg.substr(0, eq)] = arg.substr(eq + 1);
		}
		
		data.path = url.substr(0, idx);
	} else {
		data.path = url;
	}
	
	return data;
}

This way i get a JSON Object with path and parameter.

parseURL("/hello?key=val&foo=bar&something");
//{"path":"/hello","param":{"key":"val","foo":"bar","something":''}}
