[英]How to get the row id onClick in jQuery/JavaScript?
我有一個填充了動態數據的表。 最后一列有一個按鈕,當我單擊該按鈕時,我想將行 ID 傳遞給 JS function。 我需要 id,因為我正在執行 POST Ajax 請求,成功后我想獲取響應數據並使用新數據更新所選行。
這就是我要插入新行的方法:
var rowNode = myTable.row.add([1,2,3,4,5,6,7,8]).draw();
但是我能做些什么來獲取行 ID 並使用響應數據更新它?
編輯。 數據表:
<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>
由於您只想獲取clicked
的行編輯按鈕的row id
。 您可以簡單地使用table.row
function 並傳遞單擊按鈕的實際tr
。
演示(顯示存儲為名稱的actual id
(1, 2))
var table = $('#myTable').DataTable({}) //edit customer here function 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]); }

演示(顯示表的實際索引 - 索引從 0 開始到取決於您擁有的行數)
var table = $('#myTable').DataTable({}) //edit customer here function 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) }

這是我的簡單回答:
var table = $('#table-values');
$('#table-values').on( 'click', 'tr', function(){
var id = this.id;
alert( 'Clicked row id '+id );
});
簡單的。 :)
