JSON.parse for array of object
提问by
Server returns the array of object in JSON. It looks so:
服务器以 JSON 形式返回对象数组。看起来是这样的：
{"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)\/\"}
]"}
I need to parse using JSON.parse function. I'm doing this this way:
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?
}
This code is not working, it returns undefined
此代码不起作用，它返回未定义
for (var item in parsedJSON) {
alert(item.Id);
}

This works perfectly
这完美地工作
function myFunction(dataFromServer){
var parsedJSON = JSON.parse(dataFromServer.d);
for (var i=0;i<parsedJSON.length;i++) {
alert(parsedJSON[i].Id);
}
}
But this doens't
但这不
function myFunction(dataFromServer){
var parsedJSON = JSON.parse(dataFromServer.d);
for (var item in parsedJSON) {
alert(item.Id);
}
}

You can just access them as you would any object:
您可以像访问任何对象一样访问它们：
var id = item.Id;
if (item.IsGood) { ... }
If you wish to enumerate them to use somehow, have a look at this SO question.
如果您希望枚举它们以某种方式使用，请查看这个 SO question。

You can access them as you do oridinary javascript objects,
that is either as item.idor item['id']
您可以像访问普通 javascript 对象一样访问它们，即 asitem.id或item['id']
