获取url参数

方法1
//获取查询请求的URLget参数
function getQueryString(name) {
var reg = new RegExp("(^|&)" + name + “=([^&]*)(&|$)”, “i”);
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}

方法2:
Location.prototype.getParameter = function () {
var param = {};
if(this.search) {
var ps = this.search.substr(1).split(’&’);
for (var i = 0; i < ps.length; i++) {
var obj = ps[i].split(’=’);
param[obj[0]] = obj[1] || ‘’;
}
}
return param;
};
