JSON.parse用于对象数组

Question

Server以JSON格式返回对象数组.它看起来如此:

{"d":"[
  {\"Id\":1,\"IsGood\":true,\"name1\":\"name1dsres\",\"Name2\":\"name2fdsfd\",\"name3\":  \"name3fdsgfd\",\"wasBorn\":\"\\/Date(284011000000)\\/\"},
  {\"Id\":2,\"IsGood\":false,\"name1\":\"fdsfds\",\"name2\":\"gfd3im543\",\"name3\":\"3543gfdgfd\",\"WasBorned\":\"\\/Date(281486800000)\\/\"}
]"}

我需要使用JSON.parse函数进行解析.我是这样做的:

   function myFunction(dataFromServer){
      var parsedJSON = JSON.parse(dataFromServer.d);
         for (var item in parsedJSON.d) {
          // how do I get the fields of current item?
      }

此代码不起作用,它返回undefined

for (var item in parsedJSON) {
      alert(item.Id);
}

这非常有效

    function myFunction(dataFromServer){
       var parsedJSON = JSON.parse(dataFromServer.d);
       for (var i=0;i<parsedJSON.length;i++) {
            alert(parsedJSON[i].Id);
         }
 }

但这不是

    function myFunction(dataFromServer){
           var parsedJSON = JSON.parse(dataFromServer.d);
           for (var item in parsedJSON) {
               alert(item.Id);
         }
 }
