我有这个
HTML与以下jQuery:
<nav class="navigation">
<ul>
<li class="has-sub">iPad <i class="fa fa-angle-down"></i>
<ul class="sub-menu">
<li><a href="iPadAir2.php">iPad Air 2 Review</a></li>
<li><a href="iPadAir.php">iPad Air Review</a></li>
<li><a href="iPadMini2.php">iPad mini 2 Review</a></li>
</ul>
</li>
<li class="has-sub">iPhone <i class="fa fa-angle-down"></i>
<ul class="sub-menu">
<li><a href="iPhone6.php">iPhone 6 Review</a></li>
<li><a href="iPhone5s.php">iPhone 5s Review</a></li>
<li><a href="iPhone5c.php">iPhone 5c Review</a></li>
<li><a href="iPhone5.php">iPhone 5 Review</a></li>
<li><a href="iPhone4s.php">iPhone 4s Review</a></li>
</ul>
</li>
<li class="has-sub">Mac <i class="fa fa-angle-down"></i>
<ul class="sub-menu">
<li><a href="MacBook.php">MacBook Review</a></li>
<li><a href="MacBookProRetina.php">MacBook Pro w/ Retina display Review</a></li>
<li><a href="MacBookPro.php">MacBook Pro Review</a></li>
<li><a href="MacBookAir.php">MacBook Air Review</a></li>
</ul>
</li>
</ul>
</nav>
$(document).ready(function() {
$(".has-sub").click(function() {
$(this).find(".sub-menu").slideToggle(500);
$(this).parent().children(".has-sub").not(this).find(".sub-menu").slideUp(500);
});
});
你可以看到我有一类fa-angle-down.单击时,li打开但我想删除fa-angle-down类并向i类添加一类fa-angle-up.有人可以告诉我如何做到这一点?
谢谢.
编辑:
下面的导航CSS.
nav {
background : #034893;
height : 50px;
}
nav ul,
nav li,
nav a {
margin : 0;
padding : 0;
}
nav > ul > li {
color : white;
display : block;
float : left;
font-size : 18px;
line-height : 50px;
position : relative;
transition : all .3s linear;
width : 25%;
z-index : 999;
}
nav > ul > li:hover {
background : #88bffc;
color : #333;
cursor : pointer;
}
nav > ul > li > ul {
background : #034893;
left : 0;
margin : 0 auto;
position : absolute;
right : 0;
text-align : left;
}
nav ul ul a {
color : white;
display : block;
font-size : 14px;
padding : 6px 12px;
}
nav ul ul a:hover {
background : #88bffc;
}
最佳答案 EDITED这有效,检查类是否在DOM中切换.
编辑只是初始切换.fa类,它为点击的菜单项打开/关闭向下/向上.
$(".has-sub").click(function(e) {
e.preventDefault;
$this = $(this);
$this.find(".sub-menu").slideToggle(500);
$this.siblings(".has-sub").not(this).find(".sub-menu").slideUp(500);
$this.find(".fa").toggleClass('fa-angle-down fa-angle-up');
$this.siblings(".has-sub").not(this).find(".fa-angle-up").toggleClass('fa-angle-up fa-angle-down');
});
