javascript - 遍历嵌套的 json 数组

Question

我想访问 json 数组的 salesId 但 sales 也是一个数组，所以循环两次？

var json = [
  {
    'id':1,
    'sales':
    [
      {'salesId':123},
      {'salesId':456}

    ]
  },
  {
    'id':2,
   'sales':
   [
      {'salesId':789},
      {'salesId':111213}

    ]
  }
];

Answer 1

for (var i in json) {
   for (var j in json[i].sales) {
      var result = json[i].sales[j].salesId; // here "result" will get salesId
   }
}
