vue + uniapp 实现仿百度地图/高德地图/美团/支付宝 滑动面板 纯css 实现

概要

使用百度地图、各种单车APP时，对地图上的滑动面板很感兴趣，于是根据自己的理解实现了一下
之前用的js实现，滑动的时候没有原生好
这一次用的css实现

代码

<template>
  <view class="container">
    <map
      style="
        position: fixed;
        height: 100%;
        width: 100%;
        top: 0;
        left: 0;
        z-index: 0;
      "
      :enable-scroll="!isPanelTouched"
    ></map>
    <view
      style="
        height: 500rpx;
        width: 100%;
        background-color: rgba(255, 255, 255, 0.8);
        z-index: -1;
      "
    ></view>
    <view
      class="panel"
      @touchstart="onPanelTouchStart"
      @touchend="onPanelTouchEnd"
    >
      <view class="handle"></view>
      <view class="item" v-for="item in 50" :key="item">
        {{ item }}
      </view>
    </view>
    <view
      v-if="isPanelTouched"
      class="mask"
      @touchstart.stop.prevent
      @touchmove.stop.prevent
      @touchend.stop.prevent
    ></view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      isPanelTouched: false
    }
  },
  methods: {
    onPanelTouchStart() {
      this.isPanelTouched = true
    },
    onPanelTouchEnd() {
      this.isPanelTouched = false
    }
  }
}
</script>

<style scoped lang="scss">
.panel {
