javascript - 如何在 JSON 对象中搜索特定字符串值？

Question

我想搜索 JSON 对象以检查它是否包含存储在数组中的字符串值。并找出父元素。

var searchVal = ['name_1a','name_2y','name_3x'];

var json = {
"location": {
        "title1x": {
            "1": "name_1x",
            "2": "name_2x",
            "3": "name_3x",
        },
       "title2y": {
            "1": "name_1y",
            "2": "name_2y",
            "3": "name_3y",
        },
    }

    "object": {
        "title1a": {
            "1": "name_1z",
            "2": "name_2z",
            "3": "name_3z",
        },
       "title2b": {
            "1": "name_1a",
            "2": "name_2a",
            "3": "name_3a",
        },
    }
};

我想将结果传递到函数中。并分别处理它们。

name_1a -> function(title2b, object)
name_2y -> function(title2y, object)
name_3x -> function(title1x, location) etc.

。 这是我到目前为止所尝试过的。我似乎不知道如何遍历整个 JSON 对象

var searchVal = ['name_1a','name_2y','name_3x'];
  for (var i=0 ; i < searchVal.length ; i++){
    for (var k=0 ; k < ????.length ; k++)
    {
      if (json.???????? == searchVal[i]) {
        results.push(???????);
        console.log(results);

      }
    }
  }

使用下面的代码，您可以递归地找到您要查找的内容:

var json = {
    "location": {
        "title1x": {
            "1": "name_1x",
            "2": "name_2x",
            "3": "name_3x",
        },
       "title2y": {
            "1": "name_1y",
            "2": "name_2y",
            "3": "name_3y",
        },
    },
    "object": {
        "title1a": {
            "1": "name_1z",
            "2": "name_2z",
            "3": "name_3z",
        },
       "title2b": {
            "1": "name_1a",
            "2": "name_2a",
            "3": "name_3a",
        },
    }
};

var searchTest = function(varToSearch, jsonData) {

    for (var key in jsonData) {
        if(typeof(jsonData[key]) === 'object') {
            searchTest(varToSearch, jsonData[key]);
        } else {
            if(jsonData[key] == varToSearch) {
                console.log(jsonData[key]);
            }
        }
    }

}

searchTest('name_1a', json);
