访问嵌套的JSON对象 [英] Accessing nested JSON objects

问题描述

我建立一个角度应用程序，也采用了棱角分明翻译为它需要双语言版本。

I'm building an Angular App and also using angular translate as it needs to be in dual languages.

我已经的看起来的已经创造了我正确的JSON（运行它通过检查），但是当我尝试JSON对象中访问项目第1级，则返回undefined。

I've seem to have created my JSON properly (ran it through a checker), but when I try to access items within the JSON object beyond the first level, it returns undefined.

有关实例中，角翻译内我的JSON是这样的：

For instance, my JSON within the angular translations is this:

$translateProvider.translations('en', {
 "SEARCH": {
    "SEARCH" : "Recherce",
    "ABILITY" : "Abilities",
    "MANAGEMENT" : "Management Competencies",
    "PERSONAL" : "Personal Suitability"
 },

 "ABILITIES": {
    "TITLE" : "Test Title here",
    "ADVISORY": {
      "TITLE" : "Advisory Skills",
      "QUESTIONS": [
        {
          "TYPE" : "A",
          "LEVEL" : "45",
          "DESCRIPTION" : "Can you tell me how awesome you are"
        },
        {
          "TYPE" : "B",
          "LEVEL" : "100",
          "DESCRIPTION" : "Tell me about your wicked project"
        }
      ]
    }
  },

  "HEADLINE": "Oh No!",
  "SUB_HEADLINE": "Looks like you are not amazing"
});   

，并开始在JSON对象访问数据，我

And to begin accessing the data in the JSON object, I do

list = $translateProvider.translations('en');

现在，输出在控制台项目时，看看他们的工作我这样做：

Now, when outputting items in the console to see if they work I do this:

console.log(list);
var getTitle = list.HEADLINE;
var getSearch = list.SEARCH.ABILITY;
console.log(getSearch);
console.log(getTitle);

这是它得到奇数。

在'名单'返回JSON数组我指定

The 'list' returns the JSON array I specified

获取 HEADLINE 收益哦，不！

但是，让 list.SEARCH.ABILITY 返回未定义

是什么给了！？我还没有尝试过的事件访问的东西，我真正想要的真正的嵌套数组中的能力

What gives!? I haven't event tried to access the stuff I really want in the really nested array "ABILITIES"

请记住，角翻译使用格式 {{'ABILITIES.ADVISORY.TITLE|翻译}} 来输出JSON到HTML页面

Keep in mind that Angular Translate uses the format {{ 'ABILITIES.ADVISORY.TITLE' | translate }} to output the JSON onto the HTML page

推荐答案

尝试 list.SEARCH [能力。值
