jquery - jquery如何在数据表中添加多行

Question

我用过https://datatables.net/reference/api/rows.add%28%29链接有效，但数据将表显示为[object,object]。如何将对象显示为字符串。我使用过 JSON.stringify(obj) 它也不起作用。

HTML

<table id="exampleTable">
 <thead>
  <tr>
   <th>Year</th>
   <th>Month</th>
   <th>Savings</th>
  </tr>
 </thead>
 <tbody>
   <tr>
    <td>2012</td>
    <td>January</td>
    <td>$100</td>
   </tr>
   <tr>
    <td>2012</td>
    <td>February</td>
    <td>$80</td>
   </tr>
 </table>

JS

$('#addRows').click(); 

var table3 = $('#exampleTable').DataTable(); 

$('#addRows').on( 'click', function () { 
    table3.row.add(
       [ { "Year": "Tiger Nixon", "Month": "System Architect", "Savings": "$3,120" },
         {"Year": "Tiger Nixon", "Month": "System Architect", "Savings": "$3,120" }]
    ).draw(); 
});

我在 FIDDLE 中创建了两个示例.

如果您想在行添加中使用对象，您应该在数据表初始化中添加列:

JS

var table3 = $('#exampleTable').DataTable({
    data:[{ "Year": "2012", "Month": "January", "Savings": "$100" },
      { "Year": "2012", "Month": "February", "Savings": "$80" }],
    columns:[{data: 'Year'},
        {data: "Month"},
        {data: "Savings"}]
}); 

但如果您不想这样做，您可以在行添加中使用下一个语法:

JS

table4.rows.add(
   [[ "Tiger Nixon", "System Architect","$3,120" ],
     ["Tiger Nixon", "System Architect", "$3,120" ]]
).draw(); 

看fiddle它提供了更多信息。
