Find closest div that has a certain class
提问by user765368

假设我有一些这样的 HTML：
<div>
<div class="required another_class">
<div class="some_class">
<input type="checkbox" name="some_check" value="" />
</div>
</div>
</div>
How do I find the parent div of the checkbox that has the class required? As you can see above, the div has two classes requiredand another_class. Therefore something like this:
如何找到具有类的复选框的父 div required？正如你在上面看到的，div 有两个类required和another_class. 因此是这样的：
$(':checkbox').closest('div[class=required]');

You can use CSS selector in .closest(), just like that :
您可以在 中使用 CSS 选择器.closest()，就像这样：
$(':checkbox').closest('div.required');

Alternatively you can also use
或者，您也可以使用
$(':checkbox').parents('div.required')
