vue在移动端点击，滑动，长按的事件判断

思路：

1）调用js的touch的API接口分别监听touchstart,touchmove,touchend事件

2）使用计时器可以设定时间用于区分长按和点击

<template>
  <div class="about">
    <p @touchstart="start" @touchmove="move" @touchend="end">
      this is a picture
    </p>
  </div>
</template>
<script>
export default {
  data() {
    return {
      longClick: 0,
      timeOutEvent: 0
    };
  },
  methods: {
    start() {
      var that = this;
      this.longClick = 0;
      this.timeOutEvent = setTimeout(function() {
        that.longClick = 1;
        console.log("这是长按")
      }, 500);
    },
    move(e) {
      clearTimeout(this.timeOutEvent);
      this.timeOutEvent = 0;
      e.preventDefault();
      console.log("这是滑动")
    },
    end() {
      clearTimeout(this.timeOutEvent);
      if (this.timeOutEvent != 0 && this.longClick == 0) {
        //点击
        //此处为点击事件----在此处添加跳转详情页
        console.log("这是点击");
      }
      return false;
    }
  }
};
</script>
