Javascript 获取嵌套在JSON中的文本

我已经学习JSON一周了。当我尝试使用认知服务时，它将JSON格式返回到输出。这对于用户来说非常复杂。所以我只想把它的一些属性显示在屏幕上。但当我尝试访问其中的嵌套属性时，即使使用逗号或括号，它仍然不起作用！我只想去掉“text”属性并将其加在string上

{
  "language": "en",
  "orientation": "Up",
  "textAngle": 0,
  "regions": [
    {
      "boundingBox": "12,106,781,327",
      "lines": [
        {
          "boundingBox": "52,106,230,35",
          "words": [
            {
              "boundingBox": "52,108,44,33",
              "text": "60"
            },
            {
              "boundingBox": "110,106,172,35",
              "text": "Beautiful"
            }
          ]
        },
        {
          "boundingBox": "29,166,276,42",
          "words": [
            {
              "boundingBox": "29,166,99,35",
              "text": "Good"
            },
            {
              "boundingBox": "141,166,164,42",
              "text": "Morning"
            }
          ]
        },
        {
          "boundingBox": "99,229,134,39",
          "words": [
            {
              "boundingBox": "99,229,134,39",
              "text": "Images"
            }
          ]
        },
        {
          "boundingBox": "12,301,308,26",
          "words": [
            {
              "boundingBox": "12,304,20,16",
              "text": "to"
            },
            {
              "boundingBox": "38,302,52,17",
              "text": "make"
            },
            {
              "boundingBox": "96,307,44,20",
              "text": "ypur"
            },
            {
              "boundingBox": "145,301,80,18",
              "text": "timeline"
            },
            {
              "boundingBox": "231,307,89,12",
              "text": "awesome"
            }
          ]
        },
        {
          "boundingBox": "589,417,204,16",
          "words": [
            {
              "boundingBox": "589,417,204,16",
              "text": "www.birthdaywishes.expert"
            }
          ]
        }
      ]
    }
  ]
}

可以使用展开对象并打印其中的文本

var obj = {


"language": "en",
  "orientation": "Up",
  "textAngle": 0,
  "regions": [
    {
      "boundingBox": "12,106,781,327",
      "lines": [
        {
          "boundingBox": "52,106,230,35",
          "words": [
            {
              "boundingBox": "52,108,44,33",
              "text": "60"
            },
            {
              "boundingBox": "110,106,172,35",
              "text": "Beautiful"
            }
          ]
        },
        {
          "boundingBox": "29,166,276,42",
          "words": [
            {
              "boundingBox": "29,166,99,35",
              "text": "Good"
            },
            {
              "boundingBox": "141,166,164,42",
              "text": "Morning"
            }
          ]
        },
        {
          "boundingBox": "99,229,134,39",
          "words": [
            {
              "boundingBox": "99,229,134,39",
              "text": "Images"
            }
          ]
        },
        {
          "boundingBox": "12,301,308,26",
          "words": [
            {
              "boundingBox": "12,304,20,16",
              "text": "to"
            },
            {
              "boundingBox": "38,302,52,17",
              "text": "make"
            },
            {
              "boundingBox": "96,307,44,20",
              "text": "ypur"
            },
            {
              "boundingBox": "145,301,80,18",
              "text": "timeline"
            },
            {
              "boundingBox": "231,307,89,12",
              "text": "awesome"
            }
          ]
        },
        {
          "boundingBox": "589,417,204,16",
          "words": [
            {
              "boundingBox": "589,417,204,16",
              "text": "www.birthdaywishes.expert"
            }
          ]
        }
      ]
    }
  ]
}

let textArray = [];
let str = '';

obj.regions.map(region => region.lines.map(line => line.words.map(word => textArray.push(word.text))));

textArray.map(val =>{
    str = str + val + ' ';
})

console.log(str);

哪个文本属性？他们都加入了？阵列<代码>它仍然不起作用-然后发布你的代码，它有点像我的例子中的“文本”：“60”+“文本”：“美丽”+“文本”：“好”+“文本”：“早上”输入一个字符串以输出到屏幕：60早上好…我认为您必须循环并将

文本

属性转换为一个字符串。应该没那么难吧，你自己试过什么吗？请将该代码添加到您的问题中。谢谢@Mahipal。我的方法是在每一个文本中使用点和括号，但它是如此的模糊。非常感谢你

.map

绝对不是合适的方法，因为您没有创建新数组。如果您想迭代数组并在最后生成一个值，请使用

reduce

（或者如果您不知道

reduce

，则使用

forEach

-但不使用

map

，因为您没有使用映射数组）@CertainPerformance是的，这肯定可以做到。谢谢你的建议。在我提到的解决方案中，所有

map（）

都可以替换为

forEach（）

，以避免创建新数组。
