Question

我的firebase数据看起来像这样......

firebase database

在JSON下面......

我一直在尝试使用我在他们的文档中找到的内容来查询数据库，以便最终得到所有术语及其键。 如何在vocab下查询每个节点的术语属性和关键字？我正在使用它来填充自动提示。此外，词汇节点下的0和1是键......当我将数据作为JSON文件导入时，它们以这种方式出现。然而，任何新的词汇都带有独特的长键值。

我已经尝试了.on（）和.equalTo（）......但我没有任何运气。它总是似乎抓住数据库的整个词汇节点中的所有内容，并且每次都按照7整秒的顺序进行操作。这是我试图将这些术语放入数组中的一个例子...

{
    "date" : "2016-07-26T14:50:10.906Z",
    "defs" : [ {
      "AddedBy" : "",
      "date" : "2016-07-26T14:50:10.906Z",
      "def" : "it's your need to fulfill or to obtain your full potential, and have meaningful goals.",
      "image" : ""
    }, {
      "AddedBy" : "",
      "date" : "2016-07-26T14:50:10.906Z",
      "def" : "the very last stage in priority in order to be happy.",
      "image" : ""
    }, {
      "AddedBy" : "",
      "date" : "2016-07-26T14:50:10.906Z",
      "def" : "the need to be able to set goals and reach them and be able to accept one's self.",
      "image" : ""
    } ],
    "examples" : [ {
      "AddedBy" : "",
      "addDate" : "2016-07-26T14:50:10.906Z",
      "approved" : true,
      "checkDate" : "2016-07-26T14:50:10.906Z",
      "example" : "a self-actualizing person is a person who accepts themselves, sets realistic and meaningful goals and accepts change.",
      "feedback" : {
        "comment" : "",
        "grammarTrouble" : false,
        "incorrect" : false,
        "moreSpecific" : false,
        "noContext" : false
      },
      "nonExample" : false,
      "seenRecently" : [ {
        "sawOn" : "",
        "user" : ""
      } ]
    }, {
      "AddedBy" : "",
      "addDate" : "2016-07-26T14:50:10.906Z",
      "approved" : true,
      "checkDate" : "2016-07-26T14:50:10.906Z",
      "example" : "who is not self-actualizing is a person who dislikes themselves, has no goals in life, and refuses to accept change.",
      "feedback" : {
        "comment" : "",
        "grammarTrouble" : false,
        "incorrect" : false,
        "moreSpecific" : false,
        "noContext" : false
      },
      "nonExample" : false,
      "seenRecently" : [ {
        "sawOn" : "",
        "user" : ""
      } ]
    }, {
      "AddedBy" : "",
      "addDate" : "2016-07-26T14:50:10.906Z",
      "approved" : true,
      "checkDate" : "2016-07-26T14:50:10.906Z",
      "example" : "Someone who achieves to their best personal ability and faces every situation head on.",
      "feedback" : {
        "comment" : "",
        "grammarTrouble" : false,
        "incorrect" : false,
        "moreSpecific" : false,
        "noContext" : false
      },
      "nonExample" : false,
      "seenRecently" : [ {
        "sawOn" : "",
        "user" : ""
      } ]
    } ],
    "term" : "Self Actualization",
    "unit" : 0
  },

这甚至没有得到钥匙（我需要），它仍然需要大约7秒才能完成。我已经看过人们在一行中做这样的事情的视频，而且很快......不是我的运气。任何帮助将非常感激。

这里要求的是一个数据库节点的JSON样本......有400多个像这样...相关属性是term ...一直在底部。我需要一系列术语和firebase数据库密钥。如何通过查询获取它们？
