如何将嵌套的 JSON 文件添加到我创建的数据表中。我总是遇到这个问题：

DataTables 警告：表 id=tb_friendlist - JSON 响应无效。有关此错误的更多信息，请参阅 http://datatables.net/tn/1

html

<table id="tb_friendlist" class="table table-bordered table-hover" style="width:100%">
    <thead>
        <tr>
            <th>Steam ID</th>
            <th>Relationship</th>
            <th>Friend Since</th>
        </tr>
    </thead>
    <tfoot>
        <tr>
          
          <th>Steam ID</th>
          <th>Relationship</th>
          <th>Friend Since</th>
        </tr>
    </tfoot>
</table>

我正在使用的 JS/JQuery：

$.ajax(            
    type : 'GET', 
    url: 'http://api.steampowered.com/ISteamUser/GetFriendList/v0001/?key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&relationship=friend&format=json&steamid=76561197960435530',
   
    success : function(data)        
        console.log(data.friendslist);
        $('#tb_friendlist').DataTable( 
            "ajax": data,
            "columns": [
                 "data": data.friendslist.friends.steam_id ,
                 "data": data.friendslist.friends.relationship ,
                 "data": data.friendslist.friends.friend_since 
            ]
         );
    
);

JSON 文件：

【问题讨论】：

data.friendslist.friends 是一个数组 @ThumChoonTat 如何与这位先生合作？我需要使用parse 【参考方案1】：

不要将friendslist对象作为数据源传递，而是传入friendslist.friends数组

// lets take 5 friends as an example
var data = 
    "friendslist": 
        "friends": [
               "steamid": "76561197960265731", "relationship": "friend", "friend_since": 0          
            ,  "steamid": "76561197960265738", "relationship": "friend", "friend_since": 0          
            ,  "steamid": "76561197960265740", "relationship": "friend", "friend_since": 0          
            ,  "steamid": "76561197960265744", "relationship": "friend", "friend_since": 1585508613 
            ,  "steamid": "76561197960265747", "relationship": "friend", "friend_since": 0          
        ]
    
;
$('#tb_friendlist').DataTable( 
      data    : data.friendslist.friends
    , columns : [
           "data": 'steamid'      
        ,  "data": 'relationship'

【参考方案2】：

您需要在 ajax 数据表调用中提供数组

$.ajax(            
    type : 'GET', 
    url: 'http://api.steampowered.com/ISteamUser/GetFriendList/v0001/?key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&relationship=friend&format=json&steamid=76561197960435530',
   
    success : function(data)        
        console.log(data.friendslist);
        $('#tb_friendlist').DataTable( 
            "data": data.friendslist.friends,
            "columns": [
                 "data": "steam_id" ,
                 "data": "relationship" ,
                 "data": "friend_since" 
            ]
         );
    
);

这可能会解决您的问题
