微信小程序、uniapp使用touchstart和touchmove左右滑动删除。以及解决上下抖动问题。

展示效果图直接上代码

<view
 v-for="(item, index) in arr"
 :key="item.id"
 @touchstart="touchstart($event)"
 @touchmove="touchmove(index, $event)"
 :class="['touch-item', item.isTouchMove ? 'touch-move-active' : '']"
>
 <view class="content">
   <view class="date_flex">
     <view>
       <text class="date">{{ item.data }}text>
       <text class="quantity">{{ item.text }}text>
     view>
     <view>
       <u-switch space="2" v-model="value" activeColor="#FFDA00" size="40" inactiveColor="rgb(230, 230, 230)">u-switch>
     view>
   view>
   <view class="bottom_date">1, 2, 3, 4view>
 view>
 <view class="del" @tap="del(index)">
  <view class="detail">
    <view class="detail_img">
      <img :src="require('@/static/images/detail.png')" alt="">
    view>
    <view class="detail_text">删除view>
  view>
view>
view>

如果要修改里面内容直接从content这个类修改就行。

export default {
  data() {
    return {
      arr: [
        { id: '1', data: '12:00', text: '1份', isTouchMove: false },
        { id: '2', data: '12:00', text: '1份', isTouchMove: false },
      ],
      startX: 0, //开始坐标
      startY: 0,
    };
  },
  methods: {
    touchstart(e) {
      console.log('start', e);
      //开始触摸时 重置所有删除
      this.arr.forEach((v, i) => {
        if (v.isTouchMove)
          //只操作为true的
          v.isTouchMove = false;
      });
      this.startX = e.changedTouches[0].clientX;
      this.startY = e.changedTouches[0].clientY;
    },

    //滑动事件处理
    touchmove: function (indexNum, target) {
      let that = this,
        index = indexNum, //当前索引
        startX = that.startX, //开始X坐标
        startY = that.startY, //开始Y坐标
        touchMoveX = target.changedTouches[0].clientX, //滑动变化坐标
        touchMoveY = target.changedTouches[0].clientY, //滑动变化坐标
        //获取滑动角度
        angle = that.angle({ X: startX, Y: startY }, { X: touchMoveX, Y: touchMoveY });
      that.arr.forEach(function (v, i) {
        v.isTouchMove = false;
        //滑动超过30度角 return
        if (Math.abs(angle) > 15) return;
        if (i == index) {
          if (touchMoveX > startX)
            //右滑
            v.isTouchMove = false;
          //左滑
          else v.isTouchMove = true;
        }
      });
    },
    /**
     * 计算滑动角度
     * @param {Object} start 起点坐标
     * @param {Object} end 终点坐标
     */
    angle: function (start, end) {
      var _X = end.X - start.X,
        _Y = end.Y - start.Y;
      //返回角度 /Math.atan()返回数字的反正切值
      return (360 * Math.atan(_Y / _X)) / (2 * Math.PI);
    },
    //删除事件
    del: function (index) {
      this.arr.splice(index, 1);
    },
  },
};

    }
  }
}
.touch-move-active .content,
.touch-move-active .del {
  -webkit-transform: translateX(0);
  transform: translateX(0);
}

直接复制粘贴就行。拿上直接用。
如果遇到滑动会导致上下抖动用这个解决。给最外层得一个view标签加一个样式。

.rev {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: 0;
  overflow: hidden;
}

这样的话滑动会有阴影，但不会抖动，可以尝试一下看看，如果哪位能人能解决，就麻烦分享一下了 。在此谢过。
