[英]Add a class to the parent li using jquery
I would like to add an "active" class to an li when clicked. 单击后,我想向li添加一个“活动”类。 The "active" class should also be present even when you click on a sub-page of that li.
即使单击该li的子页面,也应显示“活动”类。
For example: 例如:
<ul class="primarynav">
<li id="first">
<a href="#" id="link1" class="">link1</a>
<ul class="megamenu" id="">
<li class="column"><h4 class="special"><a href="#">sub-link</a</h4></li>
</ul>
</li>
<li id="second">link2</li>
<li id="third"><a href="#" id="link3" class="">link3</a>
<ul class="megamenu" id="">
<li class="column"><h4 class="special"><a href="#">sub-link3</a></h4></li>
</ul>
</li>
</ul>
perhaps something like this 也许像这样
$('.primarynav a').click(function() {
// remove other links with 'active' class
$('.primarynav a').removeClass('active');
// set new 'active' link
$(this).addClass('active');
});
If you want to target all the children , you can use the .children()
method without any selector. 如果要定位所有子项 ,则可以使用
.children()
方法而不使用任何选择器。 This should work regardless of the complexity of the elements below the first <li>
. 无论第一个
<li>
下面的元素的复杂性如何,这都应该起作用。
$("#primarynav li").children().click(function() {(this.addClass("active"))};

Take a look at this code below. 看下面的这段代码。 It's also in a fiddle here: http://jsfiddle.net/rRkeJ/3/
它也在这里摆弄: http : //jsfiddle.net/rRkeJ/3/
It's basically the same idea as above but adapted more to what I think you want 基本上与上述相同,但更适合我想您想要的
$(".primarynav li").children().click(function() {
$(".primarynav").children().removeClass("active");
$(this).parent(".activable").addClass("active");
});
