vue-手机触屏滑动

功能：iview Carousel 走马灯，我需要在phone上实现滑动切换功能。

<div class="phone" @touchstart="phone_mouseS" @touchend="phone_mouseE"><Carousel :autoplay-speed="5000" v-model="phone_mouseMIndex" autoplay :value="0" loop v-if="menuChoose == '/'">  <CarouselItem>    <img class="img" src="../../static/common/phone_banner_index1.jpg" />  </CarouselItem>  <CarouselItem>    <img class="img" src="../../static/common/phone_banner_index1.jpg" />  </CarouselItem>  <CarouselItem>    <img class="img" src="../../static/common/phone_banner_index3.jpg" />  </CarouselItem></Carousel></div>

data() {return {  phone_mouseMIndex: 0, // phone端 滑动索引  phone_mouseMX0: 0, // phone端 滑动索引  phone_mouseMX1: 0, // phone端 滑动索引}},...// phone端 滑动开始phone_mouseS(e){  this.phone_mouseMX0 = e.changedTouches[0].pageX;},// phone端 滑动结束phone_mouseE(e){  this.phone_mouseMX1 = e.changedTouches[0].pageX;  let tag = this.phone_mouseMX1 - this.phone_mouseMX0;  if(tag >= 50){    if(this.phone_mouseMIndex > 0){      this.phone_mouseMIndex--;    }else{      this.phone_mouseMIndex = 2;    }  }  if(tag <= -50){    if(this.phone_mouseMIndex < 2){      this.phone_mouseMIndex++;    }else{      this.phone_mouseMIndex = 0;    }  }},
