如何在 jQuery/JavaScript 中获取 onClick 的行 id？
我有一个填充动态数据的表。最后一列有一个按钮，当我单击该按钮时，我想将行 ID 传递给 JS 函数。我需要 id，因为我正在执行 POST Ajax 请求，成功后我想获取响应数据并使用新数据更新所选行。
这就是我插入新行时要做的事情：
var rowNode = myTable.row.add([1,2,3,4,5,6,7,8]).draw();
但是我该怎么做才能获取行 ID 并使用响应数据更新它呢？
编辑。数据表：
<table id="myTable" class="display compact" cellspacing="0" width="100%">
<thead>
<tr>
<th>Name</th>
<th>Reg</th>
<th>Edit</th>
</tr>
</thead>
<tbody>
<?php foreach (get_all_customers_list() as $user) { ?>
<tr>
<td>
<b> <?php echo $user["recipient_name"]; ?></b>
</td>
<td>
<?php echo $user["registration_date"]; ?>
</td>
<td>
<button type="button" id="button_edit" onclick='edit_customer_request(<?php echo json_encode($user); ?>)' value="<?php echo $user; ?>" name="edit_customer">Editt</button>
</td>
</tr>
<?php }?>
</tbody>
</table>

因为您只想获得row id行clicked编辑按钮的。您可以简单地使用函数并传递单击按钮的table.row实际值。tr演示（显示actual id存储为名称的 (1, 2)）var table = $('#myTable').DataTable({})//edit customer herefunction edit_customer_request(_this) { //Getting the actual table ID var row = $(_this).parents('tr')[0]; //Data table row id console.log(table.row(row).data()[0]);}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.21/js/jquery.dataTables.min.js" integrity="sha512-BkpSL20WETFylMrcirBahHfSnY++H2O1W+UnEEO4yNIl+jI2+zowyoGJpbtk6bx97fBXf++WJHSSK2MV4ghPcg==" crossorigin="anonymous"></script><link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.21/css/jquery.dataTables.min.css" integrity="sha512-1k7mWiTNoyx2XtmI96o+hdjP8nn0f3Z2N4oF/9ZZRgijyV4omsKOXEnqL1gKQNPy2MTSP9rIEWGcH/CInulptA==" crossorigin="anonymous" /><table id="myTable" class="display compact" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Reg</th> <th>Edit</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>Tiger Blah</td> <td><button type="button" class="button_edit" onclick='edit_customer_request(this, 1)' value="1" name="edit_customer">Edit</button></td> </tr>tr> <tr> <td>2</td> <td>Blah Nixon</td> <td><button type="button" class="button_edit" onclick='edit_customer_request(this ,2)' value="2" name="edit_customer">Edit</button></td> </tr> </tbody></table>演示（显示表的实际索引 - 索引从 0 开始，具体取决于您有多少行）var table = $('#myTable').DataTable({})//edit customer herefunction edit_customer_request(_this) { //get the closest of clicked edit button var tr = $(_this).closest("tr"); //get the index of row var rowindex = tr.index(); //Index of row console.log(rowindex)}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.21/js/jquery.dataTables.min.js" integrity="sha512-BkpSL20WETFylMrcirBahHfSnY++H2O1W+UnEEO4yNIl+jI2+zowyoGJpbtk6bx97fBXf++WJHSSK2MV4ghPcg==" crossorigin="anonymous"></script><link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.21/css/jquery.dataTables.min.css" integrity="sha512-1k7mWiTNoyx2XtmI96o+hdjP8nn0f3Z2N4oF/9ZZRgijyV4omsKOXEnqL1gKQNPy2MTSP9rIEWGcH/CInulptA==" crossorigin="anonymous" /><table id="myTable" class="display compact" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Reg</th> <th>Edit</th> </tr> </thead> <tbody> <tr> <td>1</td> <td>Tiger Blah</td> <td><button type="button" class="button_edit" onclick='edit_customer_request(this, 1)' value="1" name="edit_customer">Edit</button></td> </tr>tr> <tr> <td>2</td> <td>Blah Nixon</td> <td><button type="button" class="button_edit" onclick='edit_customer_request(this ,2)' value="2" name="edit_customer">Edit</button></td> </tr> </tbody></table> -

这是我的简单回答：var table = $('#table-values');$('#table-values').on( 'click', 'tr', function(){ var id = this.id; alert( 'Clicked row id '+id ); });简单的。:)
