嵌套在JSON中

Question

我無法獲得下面的JSON來驗證。它崩潰在這裏：

"Head Coach": ["Baseball", "Basketball - Boys", "Basketball", "Volleyball - Girls", "Volleyball", "Spiritline"] 

沒有最後一個數組沒有問題。有任何想法嗎？

{ 
    "userprofileid": 12547, 
    "email": "cusdtrojans@gmail.com", 
    "first_name": "Maribel", 
    "middle_name": null, 
    "last_name": "Vasquez", 
    "prefix": null, 
    "suffix": null, 
    "schools": [{ 
     "schoolid": 417, 
     "name": "Clifton High School", 
     "addr": "4523 Appaloosa St.", 
     "addr2": null, 
     "city": "Clifton", 
     "state": "AZ", 
     "zip": "85533", 
     "roles": ["Athletic Director", 
      "Principal Secretary", 
      "Theatre", 
      "Media Adviser", 
      "Webmaster", 
      "Head Coach": ["Baseball", "Basketball - Boys", "Basketball", "Volleyball - Girls", "Volleyball", "Spiritline"] 
     ] 
    }] 
} 

Answer 1

請嘗試以下

{ 「userprofileid」：12547， 「電子郵件」： 「cusdtrojans@gmail.com」， 「FIRST_NAME」： 「馬裏貝爾」， 「middle_name」：空， 「last_name」：「Vasquez」，「prefix」：null，「suffix」：null，「schools」：[{「schoolid」：417，「name」：「Clifton High School」，「addr」：4523 Appaloosa St 「，」addr2「：null，」city「：」Clifton「，」州「：」AZ「，」zip「：」85533「，」角色「：[」運動主任「，」首席祕書「 「，」媒體顧問「，」網站管理員「，」主教練「，[」棒球「，」籃球 - 男孩「，」籃球「，」排球 - 女孩「，」排球「，」Spiritline「]]]]}

"Head Coach":應該是"Head Coach", 這是格式化版本。

{ 
    "userprofileid":12547, 
    "email":"cusdtrojans@gmail.com", 
    "first_name":"Maribel", 
    "middle_name":null, 
    "last_name":"Vasquez", 
    "prefix":null, 
    "suffix":null, 
    "schools":[ 
     { 
     "schoolid":417, 
     "name":"Clifton High School", 
     "addr":"4523 Appaloosa St.", 
     "addr2":null, 
     "city":"Clifton", 
     "state":"AZ", 
     "zip":"85533", 
     "roles":[ 
      "Athletic Director", 
      "Principal Secretary", 
      "Theatre", 
      "Media Adviser", 
      "Webmaster", 
      "Head Coach", 
      [ 
       "Baseball", 
       "Basketball - Boys", 
       "Basketball", 
       "Volleyball - Girls", 
       "Volleyball", 
       "Spiritline" 
      ] 
     ] 
     } 
    ] 
}

試試這個，這可以確保您有一個名爲'Head Coach'的參考。

{ 
    "userprofileid": 12547, 
    "email": "cusdtrojans@gmail.com", 
    "first_name": "Maribel", 
    "middle_name": null, 
    "last_name": "Vasquez", 
    "prefix": null, 
    "suffix": null, 
    "schools": [{ 
     "schoolid": 417, 
     "name": "Clifton High School", 
     "addr": "4523 Appaloosa St.", 
     "addr2": null, 
     "city": "Clifton", 
     "state": "AZ", 
     "zip": "85533", 
     "roles": [ 
      "Athletic Director", 
      "Principal Secretary", 
      "Theatre", "Media Adviser", 
      "Webmaster", { 
       "Head Coach": [ 
        "Baseball", 
        "Basketball - Boys", 
        "Basketball", 
        "Volleyball - Girls", 
        "Volleyball", 
        "Spiritline" 
       ] 
      } 
     ] 
    }] 
}

顯然，下面將是無效的

"roles": ["Athletic Director", 
    "Principal Secretary", 
    "Theatre", 
    "Media Adviser", 
    "Webmaster", 
    "Head Coach": ["Baseball", "Basketball - Boys", "Basketball", "Volleyball - Girls", "Volleyball", "Spiritline"] 
] 

因爲roles是一個數組，但你正試圖在它包括它看起來像這將是在一個對象的屬性的東西"Head Coach":。

問題出在您的數據模型上：您希望將單個角色指定爲數組中的字符串，但對於角色Head Coach，您需要其他信息，即人員爲主教練的運動。我建議做roles的對象，與角色的屬性，以及true的值，如果你只是想說明，沒有額外的信息的作用：

"roles": { 
    "Athletic Director": true, 
    "Principal Secretary": true, 
    "Theatre": true, 
    "Media Adviser": true, 
    "Webmaster": true, 
    "Head Coach": [ 
    "Baseball", 
    "Basketball - Boys", 
    "Basketball", "Volleyball - Girls", 
    "Volleyball", 
    "Spiritline" 
    ] 
} 

下面是使用這種真正簡單的例子：

Object.keys(roles).forEach(role => { 
    const value = roles[role]; 

    if (Array.isArray(value)) { 
    console.log(role, 'of', value.join(', ')); 
    } else if (value === true) { 
    console.log(role); 
    } else { 
    console.error(role, "has unknown value"); 
    } 
});
