jquery 封装页面之间获取值

$.extend({
    request: function (name) {
        var search = decodeURI(location.search.slice(1));  //decodeURI 对中文进行转码，防止乱码出现
        var arr = search.split("&");
        for (var i = 0; i < arr.length; i++) {
            var ar = arr[i].split("=");
            if (ar[0] == name) {
                if (unescape(ar[1]) == ‘undefined‘) {
                    return "";
                } else {
                    return unescape(ar[1]);
                }
            }
        }
        return "";
    }
});


页面中使用 $.request(参数名称);
