如何从单击的 TD 元素的 TR 中获取 ID 的值
How to get the Value of an ID from a TR of a Clicked TD Element
我有一个动态创建的 table 作为:
<div id="gameListDiv">
<table id="gameListTable">
<tr id="1">
<td>A</td>
<td>B</td>
<td class="tpButton">C</td>
</tr>
<tr id="2">
<td>D</td>
<td>E</td>
<td class="tpButton">F</td>
</tr>
</table>
</div>
我有一个听众:
$('#gameListDiv').on('click','.tpButton', function(toggleThisTP) {
// If user clicks C, return the row ID of '1'
// if user clicks F, return the row ID Of '2'
});
如上面的代码注释,当用户单击 table 的第 3 列中的单元格时,如何获取特定行的 ID 标记的值?
$('#gameListDiv').on('click','.tpButton', function(toggleThisTP) {
var row = $(this).closest('tr');
var id = row.attr('id');
});
这应该有效:
$('#gameListDiv').on('click','.tpButton', function() {
var id = jQuery(this).closest('tr').attr('id');
alert(id);
});
