jquery add / remove class from .parent()
提问by Thomas
i know this is incredibly easy but I have been writing and rewriting this function for an hour with no success:
我知道这非常简单,但我已经编写和重写了这个函数一个小时,但没有成功:
On click I want to add "active" to the <li>
of the clicked link and remove "active" from all the other <li>
's in the navbar.
单击时,我想将“active”添加到<li>
单击的链接的 ,并从<li>
导航栏中的所有其他's 中删除“active” 。
HTML:
HTML:
<nav>
<ul>
<li><a href="http://0327ea8.netsolhost.com/#home" class="home">Home</a></li>
<li><a href="http://0327ea8.netsolhost.com/blog/" class="blog">Blog</a></li>
<li><a href="http://0327ea8.netsolhost.com/#catalog" class="catalog">Catalog</a></li>
<li><a href="http://0327ea8.netsolhost.com/#authors" class="authors">Authors</a></li>
<li><a href="http://0327ea8.netsolhost.com/#store" class="store">Store</a></li>
</ul>
</nav>
jQuery:
jQuery:
// NAVBAR ADD ACTIVE
$("nav ul li a").click(function(){
$("nav ul li").removeClass('active');
$(this).stop().animate();
$(this).parent().addClass('active');
});
This is adding the classes just fine but I can't get it to remove.
这是添加类就好了,但我无法将其删除。
I've also tried separating it into to separate functions with no luck.
我也试过把它分成不同的功能,但没有运气。
I have the .stop().animate() in there because I have a .animate() on the hover state of the links.
我在那里有 .stop().animate() 因为我在链接的悬停状态有一个 .animate() 。
thanks!
谢谢!
edit:
编辑:
this is the jQuery for the hover and the reason I have .stop().animate()
这是悬停的 jQuery 和我有 .stop().animate() 的原因
$("nav ul li a, aside ul li.categories a, div.posts div.foot a").hover(function(){
$(this).animate({'backgroundColor' : '#edf5e9'}, 200);
},function() {
$(this).animate({'backgroundColor' : '#ccd4c8'}, 600);
});
I'm not sure why the .stop().animate() is wrong. If I don't have .animate() the active class won't stick, if I do, the active class does.
我不确定为什么 .stop().animate() 是错误的。如果我没有 .animate() 活动类就不会粘住,如果我这样做了,活动类会粘住。
I still can't get the class to remove though :-/
我仍然无法删除课程:-/

Try this:
尝试这个:
$(this).parent().siblings().removeClass('active');

Try something even simpler:
尝试更简单的事情:
$('li.active').removeClass('active');
