我对具有特定类的元素使用click事件.在click事件函数中,我需要使用相同的类获取页面上的下一个元素.我试过了：
$('.class').click(function() {
var $next = $(this).next('.class')
});
和：
$('.class').click(function() {
var $next = $(this).parent().parent().parent().next('.class')
});
.class是表中td内的div,这就是为什么三次parent().
我的HTML是这样的(.class是.drag)：
<table cellspacing="0" cellpadding="0" border="0" class="black8">
<tr class="trow1 drop trow1_over"
rel="0,1">
<td>
<div class="drop rootFolder"
rel="0,1"></div>
</td>
<td width="100%"
class="folderListOnclick">
<span>.. (koreňový adresár)</span>
</td>
<td>
</td>
<td>
</td>
</tr><tr class="trow1">
<td>
<div class="drag drop ordinaryFolder"
rel="1,1"
style="width: 40px;">
</div>
</td>
<td width="100%"
class="folderListOnclick"
rel="1">
<span>aaa</span>
</td>
<td>
<div class="button_mini folderEditOnclick"
rel="1">
<span></span>
</div>
</td>
<td>
<div class="button_mini folderDeleteOnclick"
rel="1">
<span><span>
</div>
</td>
</tr><tr class="trow1">
<td>
<div class="drag drop ordinaryFolder"
rel="19,1"
style="width: 50px;">
</div>
</td>
<td width="100%"
class="folderListOnclick"
rel="19">
<span>subaaa</span>
</td>
<td>
<div class="button_mini folderEditOnclick"
rel="19">
<span></span>
</div>
</td>
<td>
<div class="button_mini folderDeleteOnclick"
rel="19">
<span><span>
</div>
</td>
</tr>
</table>
解决方法
你可以试试：
$(".drag").click(function() {
var draggables = $(this).parents("table").find(".drag");
var $next = draggables.filter(":gt(" + draggables.index(this) + ")").first();
});
