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;}
  }
},
