在Home.vue页面使用弹窗：

<!-- 活动规则弹窗 -->
 <template>
<div>
 <div  @click="clickPopup">
            <span>点击弹出弹窗</span>
          </div>
 <Popup
      v-show="isRulesShow"
      @closeModal="isRulesShow = false"
      :show="isRulesShow"
    >
    </Popup>
</div>
</template>
<script>
import Popup from './Popup'
export default {
name:"Home",
components: {
 Popup
},
data () {
    return {
      isRulesShow:flase
      }
    },
    watch: {
    isRulesShow (v) {
      if (v) {
        //禁止主页面滑动方法在main.js
        this.noScroll()
      } else {
        //主页面可滑动
        this.canScroll()
      }
    },
  },
   methods:{
 //活动规则弹窗
    clickPopup () {
      this.isRulesShow = true
    },
 }
}
</script>
   <style lang="scss" scoped>
* {
  touch-action: pan-y;
}
</style>

解决弹窗滚动，里面的body也跟着滚动问题

在main.js中

//弹出框禁止滑动
Vue.prototype.noScroll = function () {
  var mo = function (e) { e.preventDefault() }
  document.body.style.overflow = 'hidden'
  document.addEventListener('touchmove', mo, false,{ passive: false })// 禁止页面滑动
}
 
//弹出框可以滑动
Vue.prototype.canScroll = function () {
  var mo = function (e) {
    e.preventDefault()
  }
  document.body.style.overflow = ''// 出现滚动条
  document.removeEventListener('touchmove', mo, false,{ passive: false })
}

在页面使用时：

//禁止主页面滑动
  this.noScroll()
//主页面可滑动
  this.canScroll()

//还要加上样式：
* {
  touch-action: pan-y;
}
