本文实例为大家分享了swiper4实现移动端导航切换的具体代码，供大家参考，具体内容如下
首先导入
<link rel="stylesheet" href="css/swiper.min.css" > <script src="js/jquery-1.10.1.min.js"></script> <script src="js/swiper.min.js"></script>(这里用的是Swiper 4.0.7版本)
在写入html内容
<div id=header> <div class="head-top"> <h3>商品分类</h3> </div> <div id="nav" class="swiper-container"> <ul class="swiper-wrapper"> <li class="swiper-slide active-nav"><a href="javascript:;" >手机</a></li> <li class="swiper-slide"><a href="javascript:;">厨具</a></li> <li class="swiper-slide"><a href="javascript:;">数码</a></li> <li class="swiper-slide"><a href="javascript:;">家纺</a></li> <li class="swiper-slide"><a href="javascript:;">生鲜</a></li> <li class="swiper-slide"><a href="javascript:;">家用电器</a></li> <li class="swiper-slide"><a href="javascript:;">食品饮料</a></li> <li class="swiper-slide"><a href="javascript:;">电脑/办公</a></li> <li class="swiper-slide"><a href="javascript:;">家用日用</a></li> </ul> </div> </div> <div id="page" class="swiper-container" id="page"> <div class="swiper-wrapper"> <div class="swiper-slide slidepage">手机</div> <div class="swiper-slide slidepage">厨具</div> <div class="swiper-slide slidepage">数码</div> <div class="swiper-slide slidepage">家纺</div> <div class="swiper-slide slidepage">生鲜</div> <div class="swiper-slide slidepage">家用电器</div> <div class="swiper-slide slidepage">食品饮料</div> <div class="swiper-slide slidepage">电脑/办公</div> <div class="swiper-slide slidepage">家用日用</div> </div> </div>
最后调用swiper
<script>
var myNav = new Swiper('#nav', {
spaceBetween: 10,
slidesPerView : 3,
watchSlidesProgress : true,
watchSlidesVisibility : true,
on:{
tap: function(){
myPage.slideTo( myNav.clickedIndex)
}
}
})
var myPage = new Swiper('#page',{
on:{
slideChangeTransitionStart: function(){
updateNavPosition()
}}
})
function updateNavPosition(){
$('#nav .active-nav').removeClass('active-nav');
var activeNav = $('#nav .swiper-slide').eq(myPage.activeIndex).addClass('active-nav');
if (!activeNav.hasClass('swiper-slide-visible')) {
console.log(1);
if (activeNav.index()>myNav.activeIndex) {
console.log(2);
var thumbsPerNav = Math.floor(myNav.width/activeNav.width())-1
myNav.slideTo(activeNav.index()-thumbsPerNav)
}
else {
console.log(3);
myNav.slideTo(activeNav.index())
}
}
}
</script>
全部代码如下：
