javascript - 通过对象解析

Question

我有这个对象，我想获取门户名称。我该怎么做，使用 JS 或 jQuery

对象

var Test = {};

Test.Customers = [{"CustomerItems":
                            "Portals":
                            {"id":"1","customer":"1950","resident":"yes",
                            "CustomPortals":
                                        [
                                        {"id":"11","test":"4251","portalname":"tye.jpg"},
                                         {"id":"12","test":"4251","portalname":"Lsdf.jpg"},
                                         {"id":"13","test":"4251","portalname":"nick.jpg"}
                                         ]
                            }
                    },
                    {"CustomerItems":
                            "Portals":
                            {"id":"2","customer":"1952","resident":"yes",
                            "CustomPortals":
                                        [
                                        {"id":"14","test":"4252","portalname":"Chrysanthemum2.jpg"},
                                         {"id":"15","test":"4255","portalname":"navagin.jpg"},
                                         {"id":"16","test":"4257","portalname":"jasoria.jpg"}
                                         ]
                            }
                    },
                    {"CustomerItems":
                            "Portals":
                            {"id":"3","customer":"1950","resident":"yes",
                            "CustomPortals":
                                        [
                                        {"id":"17","test":"4231","portalname":"Zsryanmum1.jpg"},
                                         {"id":"18","test":"4651","portalname":"Ltd1.jpg"},
                                         {"id":"19","test":"4281","portalname":"ser1.jpg"}
                                         ]
                            }
                    }
                ]

尝试过

 $.each(Test.Customers, function(index, value) {

                $.each(value.CustomPortals, function(innerIndex, innerValue) {
                    alert('File ' + innerValue + ' in customer ' + innerIndex);
                });

            });

但是没用

Answer 1

您的内部“.each()”循环需要遍历“CustomerItems.Portals”以到达“CustomPortals”:

            $.each(value.CustomerItems.Portals.CustomPortals, function(innerIndex, innerValue) {
                alert('File ' + innerValue + ' in customer ' + innerIndex);
            });

添加一些存在性测试可能是个好主意，但你比我更了解你的数据。

edit — @justkt 有一个非常好的观点——正如此处发布的那样，JSON 首先是无效的。因此，我上面写的内容将是正确的如果这些东西可以被解析:-)
