来自JSON文件的骨干模型显示为属性

Question

我正在尝试确定这里的问题。基本上，我正在将带有JSON内容的文件加载到backbone.js集合中。它正确地定位文件，加载内容，我可以看到（通过浏览器开发人员工具）12个JSON对象中的一个是可访问的，但它缺少其他11个对象，并且看起来加载的是被归类为“属性”。我对backbone.js有些新意，我不确定我做错了什么。代码和截图如下：

我用来从文件中加载JSON内容的代码：

var cmd = Backbone.Model.extend({});
var cmdList = Backbone.Collection.extend({
    model: cmd
});
var myCmds = new cmdList();

myCmds.fetch({
    add: true,
    url: "CustomFiles/Commands.txt",
    success: function () {
        console.log("JSON file load was successful", myCmds);
        $.each(myCmds, function (key, value) {
            console.log(key + ": " + value.Description);
        });
    },
    error: function () {
        console.log("There was some error in loading and processing the JSON file");
    }
});

以下是包含JSON内容的Commands.txt文件的缩写版本：

{
"Command": {
    "build": 1,
    "TouchedBy": "corpUser1",
    "TouchedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
    "CreatedBy": "corpUser1",
    "CreatedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 1,
    "Name": "Start Services",
    "Description": "To start all Services",
    "Type": 1,
    "Data": ""
},
"Command": {
    "build": 1,
    "TouchedBy": "corpUser1",
    "TouchedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
    "CreatedBy": "corpUser1",
    "CreatedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 2,
    "Name": "Stop Services",
    "Description": "To stop all Services",
    "Type": 2,
    "Data": ""
},
[9 other JSON objects (commands) - formatted exactly the same way...],
"Command": {
    "build": 1,
    "TouchedBy": "corpUser2",
    "TouchedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
    "CreatedBy": "corpUser2",
    "CreatedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 28,
    "Name": "Stop Services T",
    "Description": "To stop all Services for T",
    "Type": 2,
    "Data": ""
}
}

我的JSON内容似乎是正确的，但正如您从开发人员工具的屏幕截图中看到的那样，它正在加载，但它没有加载所有对象，我无法访问“描述”的值'命令'对象的属性。

在下面的屏幕截图中，您可以看到只加载了一个命令，并将其标识为属性。我是否过度分析/过度复杂，或者有什么简单的我可以忽略？

如何正确加载和迭代这些JSON对象？

更新：

我修改了Commands.txt文件，以便不再出现“Command”键，并更改了开始和结束括号，以便对象成为数组的一部分。所以，我离开了这个：

{
    "Command": {
        "build": 1,
        "TouchedBy": "corpUser1",
        "TouchedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
        "CreatedBy": "corpUser1", 
        "CreatedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
        "Active": "TRUE",
        "MSRowversion": "",
        "id": 1,
        "Name": "Start Services",
        "Description": "To start all Services",
        "Type": 1,
        "Data": ""
    },
    "Command": {
        "build": 1,
        "TouchedBy": "corpUser1",
        "TouchedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
        "CreatedBy": "corpUser1",
        "CreatedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
        "Active": "TRUE",
        "MSRowversion": "",
        "id": 2,
        "Name": "Stop Services",
        "Description": "To stop all Services",
        "Type": 2,
        "Data": ""
    },
    [9 other JSON objects (commands) - formatted exactly the same way...],
    "Command": {
        "build": 1,
        "TouchedBy": "corpUser2",
        "TouchedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
        "CreatedBy": "corpUser2",
        "CreatedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
        "Active": "TRUE",
        "MSRowversion": "",
        "id": 28,
        "Name": "Stop Services T",
        "Description": "To stop all Services for T",
        "Type": 2,
        "Data": ""
    }
}

到此：

[{
    "build": 1,
    "TouchedBy": "corpUser1",
    "TouchedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
    "CreatedBy": "corpUser1",
    "CreatedWhenUTC": "2013-10-24 06:58:15.5130000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 1,
    "Name": "Start Services",
    "Description": "To start all Services",
    "Type": 1,
    "Data": ""
},
{
    "build": 1,
    "TouchedBy": "corpUser1",
    "TouchedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
    "CreatedBy": "corpUser1",
    "CreatedWhenUTC": "2013-10-24 06:58:15.5170000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 2,
    "Name": "Stop Services",
    "Description": "To stop all Services",
    "Type": 2,
    "Data": ""
},
[9 other JSON objects (commands) - formatted exactly the same way...],
{
    "build": 1,
    "TouchedBy": "corpUser2",
    "TouchedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
    "CreatedBy": "corpUser2",
    "CreatedWhenUTC": "2014-10-30 08:48:37.0770000 +00:00",
    "Active": "TRUE",
    "MSRowversion": "",
    "id": 28,
    "Name": "Stop Services T",
    "Description": "To stop all Services for T",
    "Type": 2,
    "Data": ""
}]

这解决了我的大部分问题。我仍然有一个问题，访问该命令的一个属性值，但我会做的工作尝试找出那个部分，如果我需要，可以回来一个新的问题。

您的对象中有三个具有相同名称（Command）的键。每个键都将覆盖最后一个键，这解释了为什么只加载了一个嵌套对象。
