在jquery中解析json对象

Question

I see a lot of examples for parsing a json object in jquery using $.parseJSON and understood them. However I am missing some basics and I am not able to parse the below VALID json.

{
   "studentList":
   [
       {
           "id": 2,
           "name": "Alex",
           "opened": true
       },
       {
           "id": 3,
           "name": "Paul",
           "opened": true
       }
 ]
}

All the examples I found over the internet has a structure like below

[
       {
           "id": 2,
           "name": "Alex",
           "opened": true
       },
       {
           "id": 3,
           "name": "Paul",
           "opened": true
       }
 ]

Notice, its not enclosed in { "sudentList": } . Can someone explain the logic to parse such json?

Answer 1

The studentList has two arrays inside. So you can parse the values directly or using $.each .

var a = { "studentList": [ { "id": 2, "name": "Alex", "opened": true }, { "id": 3, "name": "Paul", "opened": true } ] };

//values shoud be Alex and Paul
console.log(a.studentList[0].name)
console.log(a.studentList[1].name)

var a = { "studentList": [ { "id": 2, "name": "Alex", "opened": true }, { "id": 3, "name": "Paul", "opened": true } ] };

//values shoud be Alex and Paul
$.each(a.studentList, function() {
    console.log(this.name);
});
