Question

我有这个包含这些数据的json文件：

{   "language": "en",   "textAngle": 0,   "orientation": "Up",   "regions": [
    {
      "boundingBox": "21,16,304,451",
      "lines": [
        {
          "boundingBox": "28,16,288,41",
          "words": [
            {
              "boundingBox": "28,16,288,41",
              "text": "NOTHING"
            }
          ]
        },
        {
          "boundingBox": "27,66,283,52",
          "words": [
            {
              "boundingBox": "27,66,283,52",
              "text": "EXISTS"
            }
          ]
        },
        {
          "boundingBox": "27,128,292,49",
          "words": [
            {
              "boundingBox": "27,128,292,49",
              "text": "EXCEPT"
            }
          ]
        },
        {
          "boundingBox": "24,188,292,54",
          "words": [
            {
              "boundingBox": "24,188,292,54",
              "text": "ATOMS"
            }
          ]
        },
        {
          "boundingBox": "22,253,297,32",
          "words": [
            {
              "boundingBox": "22,253,105,32",
              "text": "AND"
            },
            {
              "boundingBox": "144,253,175,32",
              "text": "EMPTY"
            }
          ]
        },
        {
          "boundingBox": "21,298,304,60",
          "words": [
            {
              "boundingBox": "21,298,304,60",
              "text": "SPACE."
            }
          ]
        },
        {
          "boundingBox": "26,387,294,37",
          "words": [
            {
              "boundingBox": "26,387,210,37",
              "text": "Everything"
            },
            {
              "boundingBox": "249,389,71,27",
              "text": "else"
            }
          ]
        },
        {
          "boundingBox": "127,431,198,36",
          "words": [
            {
              "boundingBox": "127,431,31,29",
              "text": "is"
            },
            {
              "boundingBox": "172,431,153,36",
              "text": "opinion."
            }
          ]
        }
      ]
    }   ] }

我尝试了不同的方法，即使使用jQuery，我也无法获得上述json文件内容中的TEXT值。然后我想将所有文本值连接成一个字符串，并有一个计数器来计算找到的所有单词“TEXT”。

任何人都可以帮助我吗？

它看起来像这样（我没有测试过，但它应该让你开始正确的道路）：

假设上述结构存储在下面的数据对象中：

var textArray = [];

if (data.hasOwnProperty("regions") && $.isArray(data.regions)) {
    var regions = data.regions;

    if (regions.hasOwnProperty("lines") && $.isArray(regions.lines)) {
        var lines = regions.lines;

        $.each(lines, function(i, line) {
            if (line.hasOwnProperty("words") && $.isArray(line.words)) {
                $.each(line.words, function(j, word) {
                    if (word.hasOwnProperty("text") && word.text) {
                        textArray.push(word.text);
                    }
                });
            }
        });
    }
}

在此代码的末尾，textArray应包含JSON结构中的所有“text”项。

如何只访问嵌套json文件中的一个元素
