仅使用一个警报即可打印所有记录

我在JSFiddle中具有以下代码，适用于此处：

var result = [ 
    {"Id": 10004, "PageName": "club"}, 
    {"Id": 10040, "PageName": "qaz"}, 
    {"Id": 10059, "PageName": "jjjjjjj"}
];

$.each(result, function(i, item) {
    alert(result[i].PageName);
});

为了查看所有结果，我必须在警报窗口中单击两次“确定”。如何仅使用一个警报显示内容？

        var cls = function () { }

        self.getData = function (mrn_) {

            /*
             if (isEmpty(mrn_)) { alert("Invalid mrn in getData()"); return false; }

您可以使用map()和join()返回带有页面名称的字符串。

var result = [ 
    {"Id": 10004, "PageName": "club"}, 
    {"Id": 10040, "PageName": "qaz"}, 
    {"Id": 10059, "PageName": "jjjjjjj"}
];

var r = result.map(function(e) {
    return e.PageName;
}).join(' ');

alert(r);
