JavaScript json loop item in array

Iterating through/Parsing JSON Object via JavaScript

解答1

Your JSON object is incorrect because it has multiple properties with the same name. You should be returning an array of "student" objects.

[
   {
     "id": 456,
     "full_name": "GOOBER ANGELA",
     "user_id": "2733245678",
     "stin": "2733212346"
   },
   {
     "id": 123,
     "full_name": "BOB, STEVE",
     "user_id": "abc213",
     "stin": "9040923411"
   }
]

Then you can iterate over it as so:

 for (var i = 0, len = objJSON.length; i < len; ++i) {
     var student = objJSON[i];
     $("<div id="" + student.id + "">" + student.full_name + " (" + student.user_id + " - " + student.stin + ")</div>")...
 }

var data = '[
  {
      "id": 456,
      "full_name": "GOOBER, ANGELA",
      "user_id": "2733245678",
      "stin": "2733212346"
  },
  {
      "id": 123,
      "full_name": "BOB, STEVE",
      "user_id": "abc213",
      "stin": "9040923411"
   }
]';

$.each(data, function(index, val) {
    alert(val.id);
    alert(val.full_name);
    alert(val.user_id);
    alert(val.stin);    
})
