swiper实现导航滚动效果

本文实例为大家分享了swiper实现导航滚动效果的具体代码，供大家参考，具体内容如下

1.需求：点击导航科目，选中元素自动往前滑动处于中间位置，tab切换

<div class="swiper-container city-column-course">
  <ul class="swiper-wrapper">
   <li class="swiper-slide on">
   <h4>推荐</h4>
   <p>Recommend</p>
   </li>
   <li class="swiper-slide">
   <h4>英语培训 </h4>
   <p>English training</p>

js：

var mySwiper = new Swiper('.city-column-course', {
   freeMode: true,
   freeModeMomentumRatio: 0.5,
   slidesPerView: 'auto',

 });
 //滑动列表，导航滑动到相应科目并居中显示
 var cityList = new Swiper('.city-course-list',{
 slidesPerView : 1,
 onSlideChangeEnd: function(swiper){
  var num=swiper.activeIndex;
  $(".city-column-course").find("li").eq(num).addClass("on").siblings("li").removeClass("on");
  slide = mySwiper.slides[num];
  slideLeft = slide.offsetLeft;
  slideWidth = slide.clientWidth;
  slideCenter = slideLeft + slideWidth / 2;
  // 被点击slide的中心点
  mySwiper.setWrapperTransition(300);

  if (slideCenter < swiperWidth / 2) {

    mySwiper.setWrapperTranslate(0);

  } else if (slideCenter > maxWidth) {

    mySwiper.setWrapperTranslate(maxTranslate);

  } else {

    nowTlanslate = slideCenter - swiperWidth / 2;

    mySwiper.setWrapperTranslate(-nowTlanslate);

  }
 }
 })
 swiperWidth = mySwiper.container[0].clientWidth;
 maxTranslate = mySwiper.maxTranslate();
 maxWidth = -maxTranslate + swiperWidth / 2;
 $(".city-column-course").on('touchstart', function (e) {
   e.preventDefault();
 });
 //document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
 mySwiper.on('tap', function (swiper, e) {
   // e.preventDefault()
   slide = swiper.slides[swiper.clickedIndex];
   slideLeft = slide.offsetLeft;
   slideWidth = slide.clientWidth;
   slideCenter = slideLeft + slideWidth / 2;
   // 被点击slide的中心点
   mySwiper.setWrapperTransition(300);

   if (slideCenter < swiperWidth / 2) {

     mySwiper.setWrapperTranslate(0);

   } else if (slideCenter > maxWidth) {

     mySwiper.setWrapperTranslate(maxTranslate);

   } else {

     nowTlanslate = slideCenter - swiperWidth / 2;

     mySwiper.setWrapperTranslate(-nowTlanslate);

   }
   $(".city-column-course .on").removeClass('on');
   $(".city-column-course .swiper-slide").eq(swiper.clickedIndex).addClass('on');
 cityList.slideTo(swiper.clickedIndex, 500, false);//切换到第一个slide

});

2.需求：滑动这块，导航选中的元素随着变化

<ul class="index-column-edu-nav clearfix">
   <li class="on"><a href="javascript:;" >培训汇</a></li>
   <li><a href="javascript:;" >最新知识</a></li>

js：

 var num=$(this).index();
 indexEdu.slideTo(num, 500, false);//切换到第n个slide，速度为1秒
 })
