Question

我有以下嵌套的数组和对象的JSON数据

我需要在javascript或NodeJS或AngularJS中更新字符串中从英语到西班牙语的所有键值

    {
      "firstrootkey" : [ //Array of 6 objects 
      {  //1st object
        "key1" : "valueinstring",
        "key2" : randomnumbers
      },..... ],
      "secondrootkey" : { //having 7 objects 
        "One" : [ { //each object having array of n objects 
          "name" : "valueinstring",
          "id" : randomnumbers
        }, ......],
        "two two" : [ { // array of m objects
          "keya" : "valueinstring",
          "keyb" : randomnumbers
        },.......],
      .
      .
      .

      },
      "third root key" : { //having n objects 
        "sdfdsfsfs" : [ { //each object having array of n objects
          "keyc" : "valueinstring",
          "keyhuh" : 858556
          "hgjhgj" : 6789
        },.... ],
        .
        .
        .
        .
        .
        }
    }

我尝试了方法，但没有一个工作......
方法之一

   for (var rootKey in jsonEnglish) {
    var rootValue = jsonEnglish[rootKey];
      if (rootValue.isArray) { // function iterate Array objects         
        //loop each array
          // if every array is object -- function iterate object 
            // find value in object 
              //if value not array and object 
                 // then pass value to translator 
                  //and update the value with translated value
              //else if its object
                  //

给出一些指示

好的，首先在http://jsonlint.com/

验证您的JSON

然后在javascript中，您可以访问json并将其与XMLHttpRequest（）

一起使用

var xmlhttp = new XMLHttpRequest();
        var url = "yourdata.json";

        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                var json_array = JSON.parse(xmlhttp.responseText);                    
                parseJson(json_array);
        }

    xmlhttp.open("GET", url, true);
    xmlhttp.send();

    json_data += "<p>Variable Access through array structure: " + json_array.firstrootkey[0].key1+ "</p>";
    json_data += "<p>Access Array inside array item: " + json_array.secondrootkey[0].one[0].name + "</p>";

    document.getElementById("display_json").innerHTML = json_data;

此外，第7行还有语法错误。另外，要测试代码，您需要一个有效的Web服务器。我更喜欢appserv。

以下是JSONlint.com上正确并验证的一些JSON

{
    "firstrootkey": [{
    "firstName": "Shane",
    "lastName": "Burton",
    "id": [
        1, 2, 3, 4, 5, 6, 7, 8
    ],
    "credits": "24"
}],
"secondrootkey": [{
    "One": [{
        "firstName": "Shane",
        "lastName": "Burton",
        "id": [
            1, 2, 3, 4, 5, 6, 7, 8
        ],
        "credits": "24"
    }]
}]
}

第二个JSON OBJECT每组括号代表数据库/列表中的一行

由于你使用的是foreach循环，为了简单起见，我会把它作为一个对象。

{
"foreachloopobject": [{
    "firstrootkey": [{
        "firstName": "Shane",
        "lastName": "Burton",
        "id": [
            1, 2, 3, 4, 5, 6, 7, 8
        ],
        "credits": "24"
    }],
    "secondrootkey": [{
        "One": [{
            "firstName": "Shane",
            "lastName": "Burton",
            "id": [
                1, 2, 3, 4, 5, 6, 7, 8
            ],
            "credits": "24"
        }]
    }],
    "firstrootkey": [{
        "firstName": "Shane",
        "lastName": "Burton",
        "id": [
            1, 2, 3, 4, 5, 6, 7, 8
        ],
        "credits": "24"
    }],
    "secondrootkey": [{
        "One": [{
            "firstName": "Shane",
            "lastName": "Burton",
            "id": [
                1, 2, 3, 4, 5, 6, 7, 8
            ],
            "credits": "24"
        }]
    }]
}]
}
