html传参数 js工具类

var QueryUtils = {
    GetQueryString: function (name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
        var r = window.location.search.substr(1).match(reg);
        if (r != null) return unescape(r[2]);
        return null;
    }
};

字符编码用escape("XXX"),解码用unescape("XXX")
