js获取链接?后面所有参数

function getRequest() {
	var url = location.search; //获取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]] = unescape(strs[i].split("=")[1]);
			//解决中文参数问题
			theRequest[strs[i].split("=")[0]] = decodeURI(strs[i].split("=")[1]);
		}
	}
	return theRequest;
}
