帮助使用 jQuery 添加类
我正在尝试根据悬停在哪个链接上更改导航底部边框颜色,底部边框颜色应更改以匹配悬停链接的颜色,当链接失去焦点或悬停时,导航底部边框应返回到它是原始颜色,下面是我的 HTML 和 jQuery。
<nav>
<ul class="<?php echo $ul; ?>">
<li class="home"><a class="home" href="/">Home</a></li>
<li class="letters"><a class="letters" href="/product/type/letters">Letters</a></li>
<li class="business active"><a class="active business" href="/product/type/business">Business</a></li>
<li class="cards"><a class="cards" href="/product/type/cards">Cards</a></li>
<li class="gifts"><a class="gifts"href="/product/gifts">Gifts</a></li>
</ul>
</nav>
/jQuery/
$('nav li a').hover(function(){
var orginalClass = $(this).parent().parent().attr('class');
$(this).parent().parent().attr('class', '');
var classType = $(this).attr('class');
$(this).parent().parent().addClass(classType);
},
function() {
$(this).parent().parent().attr('class', '');
$(this).addClass(orginalClass);
});
I am trying to change my navigation bottom border color based on what link is hovered over, the bottom border color should change to match that of the hovered link, when when the link loses focus or hover, then the navigation bottom-border should return to it's original color, below is my HTML and jQuery.
<nav>
<ul class="<?php echo $ul; ?>">
<li class="home"><a class="home" href="/">Home</a></li>
<li class="letters"><a class="letters" href="/product/type/letters">Letters</a></li>
<li class="business active"><a class="active business" href="/product/type/business">Business</a></li>
<li class="cards"><a class="cards" href="/product/type/cards">Cards</a></li>
<li class="gifts"><a class="gifts"href="/product/gifts">Gifts</a></li>
</ul>
</nav>
/jQuery/
$('nav li a').hover(function(){
var orginalClass = $(this).parent().parent().attr('class');
$(this).parent().parent().attr('class', '');
var classType = $(this).attr('class');
$(this).parent().parent().addClass(classType);
},
function() {
$(this).parent().parent().attr('class', '');
$(this).addClass(orginalClass);
});

问题是“originalClass”变量的范围。它位于第一个悬停函数的本地范围内,因此在第二个悬停函数中无法访问它。
您应该做的只是添加和删除第二个 CSS 类,该类会覆盖第一个的设置。
The problem is the scope of your "originalClass" variable. It is in the local scope of the first hover function, so it is inaccessible in the second.
What you should be doing is simply adding and removing a second CSS class that overwrites the settings of the first.
