javascript - JSON.parse 数组嵌套元素不起作用

Question

我收到此错误消息:

SyntaxError: JSON.parse: expected ',' or ']' after array element at line 4 column 18 of the JSON data.

我认为这是因为我在数组中有一个对象，也许这是不允许的。但我需要经验丰富的开发人员对此进行确认。你能把对象放在 json 的数组中吗？

HTML

<div id="ex1"><h2>Example 1</h2><p></p><h4>results:</h4></div>

Javascript

var message;

  (function loadAjax()
    { var request;
        if (window.XMLHttpRequest)
            {
                request = new XMLHttpRequest();
            }
     else{

         request = new ActiveXObject('Microsoft,XMLHTTP');
     }

     request.open('GET','human.json');

     request.onreadystatechange = function()
     {
         if(request.readyState == 4 && request.status == 200)
             {

                 message = request.responseText;
                 var obj = JSON.parse(message);
                 var text = obj.job[0].hospital;
                 attach('ex1',text,'p');
             }
     }

     request.send();

    })(); 

JSON

{
  "sex":{"male":{"fname":["Michael","Tom"]} ,"female":{"fname":["Alice","Katie"]}},
  "age":[16,80],
  "job":["medical":{"hospital": "doctor"}, "education":{"school":"teacher"} ]
}

Answer 1

这是不正确的:

"job":["medical":{"hospital": "doctor"}, "education":{"school":"teacher"} ]

这是正确的:

"job": {"medical": {"hospital": "doctor"}, "education": {"school": "teacher"} }

请注意，我将 [] 更改为 {}

方括号用于数组(许多单独的项目)。示例:

{ "my_array": [1, 2, "three"] }      <-- Notice that the items in square brackets
                                         so not assign a value such as "key": "value"

curl 用于关联条目(许多 "key": "value" 项)。示例:

{ "my_association": { "dogs": "rule", "cats": "drool" } }
