Question

我想从两个不同列中的值呈现到我的jQuery的数据表

$(document).ready(function(){ 

    var table = $('#table').DataTable({ 

     "ajax": { 
       "url": "data.json", 
       "dataSrc": "", 
      }, 

     "columnDefs": [ 
      { 
       "render": function (data, type, row) { 
        var result = 'The id is ' + data[0] + ' and the name is ' + data[1]; 
         return result; 
        }, 
        "targets": 0, 
       },  

     ], 

     "columns": [ 
       { 
        "data": "id" 
       }, 
       { 
        "data": "name" 
       } 
      ] 
    }); 

}); 

data.json：

[{ 
    "id": "12", 
    "name": "Laura" 
}] 

但我的结果是：

The id is 12 and the name is undefined

请更改以下：

"columnDefs": [ 
      { 
       "render": function (data, type, row) { 
        var result = 'The id is ' + row["id"] + ' and the name is ' + row["name"]; 
        console.log(result); 
         return result; 
        }, 
        "targets": 0, 
       },  

     ] 

使用row["id"]而不是data[0];
