记录一下使用swiper遇到的坑

loop

设置为true 则开启loop模式。loop模式：会在原本slide前后复制若干个slide(默认一个)并在合适的时候切换，让Swiper看起来是循环的。
loop模式在与free模式同用时会产生抖动，因为free模式下没有复制slide的时间点。

这里打开循环模式的时候就会复制slide

使用renderBullet(分页器)的时候尽量不要打开循环模式

<swiper :options="swiperOption2" ref="mySwiper">

swiperOption2: {
         autoplay: false,
         loop: true//这里我打开了循环
        slidesPerView: 3,//设置slider容器能够同时显示的slides数量
        slidesPerGroup: 3,//定义slides的数量多少为一组,这里一次切换一组也就是切换了3个
        slidesPerColumn: 2,//多行布局里面每列的slide数量
        slidesPerColumnFill: "column",//这里以列的形式排列
        pagination: {
          el: ".swiper-pagination",
          clickable: true,
          renderBullet: function(index, className) {
            let text = "";
            switch (index) {
              case 0:
                text = "全部";
                break;
              case 1:
                text = "网站";
                break;
              case 2:
                text = "小程序";
                break;
              case 3:
                text = "APP";
                break;
            }
            return '<span class="' + className + '">' + text  + "</span>";
          }
        },
        

       
      }

这里生成的按钮数量是按照你的slide数量比例来生成的,当你打开loop(循环模式)就会前后复制若干个slide,这样就会干扰生成的按钮数量,从而到不到你预想的效果,这是一个坑,再次记录希望自己不会再次掉进这个坑
