知识点
-
slideTo()：控制Swiper切换到指定slide。
mySwiper.slideTo(index, speed, runCallbacks)数名 类型 是否必填 描述 ndex num 必选 指定将要切换到的slide的索引 peed num 可选 切换速度(单位ms) unCallbacks boolean 可选 设置为false时不会触发transition回调函数 -
touchMove：移动端触摸移动事件
-
watchSlidesProgress：开启这个参数来计算每个slide的progress(进度、进程)，Swiper的progress无需设置即开启。
-
swiper的progress值为0-1，当前展示的slide的progress值为0，下一个为-1，上一个为1，以此类推。
-
setTranslate()
当设置wrapper的偏移量时执行。可选swiper对象和wrapper的偏移量作为参数。 -
activeIndex。返回当前活动块(激活块)的索引。loop模式下注意该值会被加上复制的slide数。
