Question

的Json --------------------------

{ "data": [
  {
  "name": "Garrett Winters",
  "designation": "Accountant",
      "salary": "$170,750",
      },
    {
      "name": "Brielle Williamson",
      "designation": "Integration Specialist",
      "salary": "$372,000",
      }
]
}

HTML -----------------

 <script type="text/javascript">
    $(document).ready(function() {
        $('#empTable').dataTable({
            "ajax": "empdata.json",
            "async": false,
            "columns": [
                {"data": "name"},
                {"data": "designation"},
                {"data": "salary"},

            ]
        });   
    });
    </script>

我没有将列硬编码为名称，名称和工资，而是想阅读JSON并填充列名。有人可以帮助我吗？

如果响应中的每个对象具有相同的形状，则使用第一个响应的键创建一个columns数组。

var columnNames = Object.keys(response.data[0]) 
// Or whatever variable the data is in.  You call Object.keys() 
// with an object and it will return an array of the keys.  
//eg.  Object.keys({ 'one': 1, 'ball': 2}) will return ['one', 'ball']

var columns = columnNames.map(name => {
    return {"data": name}
});

The columns variable would be a dynamic version of your hard coded columns.

如何在JQuery数据表中使用Json动态填充列名？
