如何訪問JSON的元素角2

Question

當我做

loadPeople(){ 

    this.myService.load().then(data => { 
      this.people = data; 
      alert(this.people); 
     }); 
    } 

它提醒JSON爲：

{ 
"status": "true", 
"statusCode": 200, 
"response": [{ 
    "user_id": "92", 
    "firstname": "joy", 
    "lastname": "Panchal", 
    "email": "joy@gmail.com", 
    "password": "7Y7+K0vZIVWPDUQH++Iu+/+tMZ", 
    "user_type_id": "1" 
}, { 
    "user_id": "89", 
    "firstname": "mark", 
    "lastname": "haris", 
    "email": "mark@gmail.com", 
    "password": "4JICqnTkR8ysTI+nQQ+rpfAf7e", 
    "user_type_id": "1" 
}] 

}

現在

我試圖通過

訪問 「迴應」

loadPeople(){ 

this.myService.load().then(data => { 
     this.people = data.response; 
     alert(this.people); 
    }); 
} 

但它警報爲「未定義」。

任何人都可以告訴我在哪裏失蹤？

Answer 1

您可以訪問這個樣子。請嘗試。

`loadPeople(){ 
    this.myService.load().then(data => { 
    this.people = JSON.parse(data.response); 
    alert(this.people); 
}); 

}`

Answer 2

你需要解析JSON第一：

this.myService.load().then(data => { 
    let res = JSON.parse(data); 
    this.people = res.response; 
    alert(this.people); 
    }); 
}
