谷歌Chrome应用: chrome.storage.local

Question

我正在努力找出为什么在我正在开发的应用程序中会发生以下情况：

因此，我读取了一个JSON文件，希望在其中读取并保存他在localStorage上的内容，在chrome应用程序中，它是chrome.storage.local

因此，我从一个json文件中获得了以下内容：

{
  "schedule": {
    "id": "416a18d6-7e42-4f8a-ac24-e902abe76f39",
    "name": "blabla",
    "updatedOn": "2013-09-08T16:34:41.000Z",
    "etag": "esxrdctfvygbuhnij5464df7g8hu",
    "applications": [
      {
        "id": "app001",
        "type": "text/html",
        "src": "http://www.google.com"
      },
      {
        "id": "app002",
        "type": "text/html",
        "src": "http://www.stackoverflow.com"
      }
    ],
    "normalContent": [
      {
        "layout_id": "layout001",
        "layout_name": "layout1",
        "layout_dur": "indefinite",
        "regions": [
          {
            "region_id": "region001",
            "region_name": "regiao1",
            "left": "0",
            "top": "0",
            "width": "0.5",
            "height": "1",
            "minWidth": "0",
            "minHeight": "0",
            "scheduleItem": "container",
            "limitCycle": "1",
            "selector": "seq",
            "containerList": [
              {
                "cid": "app001",
                "dur": "25"
              },
              {
                "cid": "app002",
                "dur": "15"
              }
            ]
          },
          {
            "region_id": "region002",
            "region_name": "regiao2",
            "left": "0.5",
            "top": "0",
            "width": "0.5",
            "height": "1",
            "minWidth": "0",
            "minHeight": "0",
            "scheduleItem": "container",
            "limitCycle": "1",
            "selector": "seq",
            "containerList": [
              {
                "cid": "app002",
                "dur": "15"
              },
              {
                "cid": "app001",
                "dur": "15"
              }
            ]
          }
        ]
      }
    ]
  }
}

因此，我得到了这个，然后我使用以下命令将内容保存在存储中：

chrome.storage.local.set({playerSchedule:this.schedule}, function(){
    console.log('saved!')       
});

稍后，当我使用以下命令读取存储的内容时：

chrome.storage.local.get(["playerSchedule", "playerScheduleType"], function (res) {
    self.currentSchedule = res.playerSchedule;
    self.scheduleType = res.playerScheduleType;
});

这是我得到的：

{
  "schedule": {
    "applications": [
      {
        "id": "app001",
        "type": "text/html",
        "src": "http://www.google.com"
      },
      {
        "id": "app002",
        "type": "text/html",
        "src": "http://www.stackoverflow.com"
      }
    ],
    "etag": "esxrdctfvygbuhnij5464df7g8hu",
    "id": "416a18d6-7e42-4f8a-ac24-e902abe76f39",
    "name": "blabla",
    "normalContent": [
      {
        "layout_dur": "indefinite",
        "layout_id": "layout001",
        "layout_name": "layout1",       
        "regions": [
          {
            ...
            "containerList": [
            ]
          },
          {
            ...
            "containerList": [
            ]
          }
        ]
      }
    ],
    "updatedOn": "2013-09-08T16:34:41.000Z"    
  }
}

正如您所看到的，我阅读的内容是按字母顺序排列的，而containerList中的内容是空的。为什么会发生这种情况呢？我通过将对象转换为字符串并将其存储来解决了这个问题，但我想知道为什么将对象另存为对象时，我会将其作为对象读取，或者是我遗漏了什么？

提前谢谢。
