JS獲取url中的指定參數

function GetRequest() {
	var url = location.search; //獲取url中"?"符后的字串
	var theRequest = new Object();
	if (url.indexOf("?") != -1) {
		var str = url.substr(1);
		strs = str.split("&");
		for(var i = 0; i < strs.length; i ++) {
			theRequest[strs[i].split("=")[0]] = decodeURI(strs[i].split("=")[1]);
		}
	}
	return theRequest;
}

使用：

var Request = new Object();
Request = GetRequest();
var 變量名 = Request['要提取的URL中的變量名'];
