Question

我创建了一个JSON对象，其中包含两个数组。我在网上搜索了如何提取数据，但我尝试过的所有代码都返回了“undefined”或[object object]。

请你看看我的例子并告诉我如何做到这一点？

var IETMObj = {
    "allItems": [{ 
         "sFile": "Test.html",
         "Applicability": [{   // second dimension
                            "ApplicID": "subj_1",
                            "ApplicDisp": "Driving",
                            "Condition": "In rain"
                    },{
                            "ApplicID": "subj_2",
                            "ApplicDisp": "Running",
                            "Condition": "Uphill"
                    }]
            }]
  };

  for (var i = 0; i < IETMObj.length; i++){
      document.write("<br><br>array index: " + i);
  var obj = IETMObj[i];
  for (var key in obj){
    var value = obj[key];
    document.write("<br> - " + key + ": " + value);
  }
}


  </script>

循环遍历多维JSON数组并在javascript中获取值
