動態節點生成功能

Question

var v = [ 
    { 
     "message": { 
      "code": "S200", 
      "message": "Success" 
     }, 
     "data": { 
      "car": [ 
       { 
        "id": 1, 
        "val": "Toyota" 
       }, 
       { 
        "id": 2, 
        "val": "Honda" 
       }, 
       { 
        "id": 3, 
        "val": "Nissan" 
       } 
      ], 
      "truck": [ 
       { 
        "id": 1, 
        "val": "Benz" 
       }, 
       { 
        "id": 1, 
        "val": "Volvo" 
       } 
      ] 
     } 
    } 
] 

我有一個如上所示的動態json。
如何動態地在不需要使用v [0]，v [1]等的情況下獲得v [0] .data.car節點）。哈希圖是可能的嗎？

Answer 1

您需要通過在angularjs數組進行迭代，這樣

v.forEach(function(element){ 
    console.log(element.data.car[0]);//Over here you can again iterate the car array, I have used the first element instead 
});
