将微信小程序切换到后台一段时间,再打开微信小程序,出现卡死闪烁抖动
// 重点是方法使用了 animationfinish 在动画结束后再进行赋值操作<swiper class="swiper_box" :current="current" @animationfinish="animationfinishChange" autoplay circular indicator-dots indicator-color="rgba(255, 255, 255, 0.6)" indicator-active-color="#fff"><swiper-item v-for="item in bannerList" :key="item.url">swiper content</swiper-item></swiper>scriptdata(){return{current :0 }}methods:{animationfinishChange(e) {this.current = e.detail.current;}}
如需同时设置索引值,并获取当前change事件
绑定事件animationfinish,在动画结束后进行赋值,避免出现闪烁卡死问题
仅需索引值,直接data定义current,监听change事件,给current赋值change返回的event.detail.current
<swiper class="swiper_box" @change="bannerChange" autoplay circular indicator-dots indicator-color="rgba(255, 255, 255, 0.6)" indicator-active-color="#fff"><swiper-item v-for="item in bannerList" :key="item.url">swiper content</swiper-item></swiper>scriptbannerChange(e) {this.current = e.detail.current;}
