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; } }}
