我想找到最接近的tr也匹配特定的类名称。选择器不返回任何匹配。我不了解什么?JQuery使用最近(“element.class”)
例如:
<table>
<tbody class="category" id="cat-1">
<tr class="category-head">
<th>Category 1</th>
</tr>
<tr class="category-item">
<th>Item 1</th>
</tr>
<tr>
<td>This is a description of category item 1</td>
</tr>
<tr>
<td><input type="text" name="c1_i1_input" id="c1_i1_input" class="category-item-input" /></td>
</tr>
<tr class="category-item">
<th>Item 2</th>
</tr>
<tr>
<td>This is a description of category item 2</td>
</tr>
<tr>
<td><input type="text" name="c1_i2_input" id="c1_i2_input" class="category-item-input" /></td>
</tr>
</tbody>
</table>
<script type="text/javascript">
$(document).ready(function() {
$(".category-item-input").change(function() {
//this works, returning the closest tr
alert($(this).closest("tr").html());
//this returns null?
alert($(this).closest("tr.category-item").html());
});
});</script>
