How to select an element which parent is not specified class?
提问by Naoise Golden
I want to hide an element if its parent does not have a certain class:
如果它的父元素没有某个类，我想隐藏它：
HTML
HTML
<li class="current_page_parent">
<a href="parent.html">Parent</a>
<ul class="children">
<li>foo</li>
<li>bar</li>
</ul>
</li>
jQuery
jQuery
jQuery("ul.children").hide();
Currently always hides <ul class="children">regardless of class. I would like to close it only if parent is :notan <li class="current_page_parent">.
目前总是隐藏，<ul class="children">无论等级如何。我想只有关闭它，如果父母是:not一个<li class="current_page_parent">。
I've tried:
我试过了：
jQuery("ul.children:not(:parent.current_page_ancestor)").hide();
with no luck.
没有运气。

尝试这个：
jQuery("li:not(.current_page_parent) ul.children").hide();

You probably want to firstfilter out the ulelements with a "bad" parent and thenselect all the children:
您可能希望首先过滤掉ul具有“坏”父级的元素，然后选择所有子级：
jQuery("ul:not(:parent.current_page_ancestor).children")

$('ul').filter(function() {
return $(this).parent('.current_page_parent').length === 0
}).hide();
