jQuery Datatables 大数据集 Uncaught TypeError : Cannot read property 'mData' of undefined

Question

因此，我在使用 php 从数据库迭代的一大组行上收到控制台错误。我正在用 metronic 主题初始化它。正如你所看到的，我有我的头部和 body 。

我怀疑问题可能与输出的大小有关，并且可能需要使用其他方法，任何指导表示赞赏

<table id="sample_1" class="table table-striped table-bordered table-hover">
    <thead>
          <tr>
            <th class="table-checkbox">
              <input type="checkbox" class="group-checkable" data-set="#sample_1 .checkboxes"/>
            </th>
            <th>Name</th>
            <th>Source</th>
            <th>Email</th>
            <th>Customer</th>
            <th>Created</th>
            <th>Login</th>
            <th>Active</th>
            <th>Role</th>
            <th>Incentive</th>
            <th>View</th>
            <th>Switch</th>
            <th>Email</th>
          </tr>        
        </thead>
      <tbody>

      <?php
        $users=user::get_all($filter);
        if($users){
          foreach($users as $row){
            $customer=user::get_cutomer_name_by_source_id($row['source_id']);
            ?>
            <tr class='odd gradeX'>
              <td><input type='checkbox' class='checkboxes' value='1'/></td>
              <td><?php echo $row['first_name']." ".$row['last_name']; ?></td>
              <td><?php echo $row['source_id']; ?></td>
              <td><?php echo $row['email']; ?></td>
              <td><?php echo $customer; ?></td>
              <td><?php echo date("m/d/Y", strtotime($row["created"])); ?></td>
              <td><?php if($row['login']!=NULL){echo date("m/d/Y",$row['login']);} ?></td>
              <td><?php if($row['active']==1){echo "Yes";}else{echo "No";} ?></td>
              <td><?php echo user::get_role_name($row['rid']); ?></td>
              <td><?php 
                if($row['cash_incentive']==1){echo "Cash";}else{echo "Regular";} ?>
                </td>
              <td><a href='user-edit?uid="<?php echo $row['uid']; ?>"'>View </a></td>
              <td><a href='switch?email="<?php echo $row['email']; ?>"'> Switch</a></td>
              <td><input type='checkbox' name='email-list[]' value='<?php echo $row['email']; ?>'></td>
            </tr>   
          <?php }
        }
      ?>

这是数据表的 metronic 初始化:

Answer 1

原因

columns 指定的数组中的项目数选项应匹配 <td> 的编号元素。 columns 中有 12 个元素数组和 13 <td>元素。

来自manual :

Note that if you use columns to define your columns, you must have an entry in the array for every single column that you have in your table (these can be null if you don't which to specify any options).

解决方案

将额外对象添加到 columns数组以匹配 HTML 中的列数。

或者您可以替换 columns与 columnDefs完全是为了可读性。

"columnDefs": [{
      "orderable": false,
      "searchable": false,
      "targets": [0]
   }, {
      "orderable": false,
      "targets": [2, 3, 11, 12]
   }
],
