我很难找出为什么在我正在开发的应用程序中发生以下情况:

所以我读了一个 JSON 文件,我想在其中读取他的内容并将其保存在 localStorage 上,在 chrome 应用程序中是 chrome.storage.local

所以我从一个 json 文件中得到以下信息:

{
  "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"
              }
            ]
          }
        ]
      }
    ]
  }
}

所以我得到了这个,然后我使用以下方法将内容保存在存储中:

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

后来当我阅读使用存储的内容时:

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

这就是我得到的:

{
  "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"    
  }
}

如您所见,我阅读的内容按字母顺序排列,而 containerList 中的内容为空。为什么会发生这种情况?我通过将对象转换为字符串并存储它来解决这个问题,但我想知道为什么保存为对象我是从作为对象读取的,还是我缺少什么?

提前致谢。

这可能是http://code.google.com/p/chromium/issues/detail?id=277647。Chrome 31 的修复工作正在进行中。
