修复自定义弹框穿透触发scroll-view下拉刷新bug

解决思路：

弹框出现的时候，禁止掉scroll-view的自定义下拉刷新

父组件---scroll-view

HTML：
<view class="tab-content">
        <scroll-view
          class="scroll"
          :scroll-y='true'
          :refresher-enabled="refershEnable"
          :refresher-triggered="refresherTriggered"
          @refresherrefresh="onRefresh"
          @refresherrestore="refresherrestore"
          @refresherabort="refresherabort"
        >
          <!-- 详情信息 -->
          <messageView
            v-if="clickTab == 'message'"
            :mushroomKey="mushroomKey"
            ref='message'
            @getModal='getModal'
          />s

          <!-- 数据分析 -->
          <pieChartView
            v-if="clickTab == 'pieChart'"
            :mushroomKey='mushroomKey'
            ref='pieChart'
          />
        </scroll-view>
      </view>
    </view>

js：
	data() {
		return {
			refershEnable: true, // 是否开启下拉刷新，true开启，false关闭，则下拉刷新失效
		}
	}
    methods: {
		getModal(show_modal) {
		      this.show_modal = show_modal;
		      if (show_modal) {
		        this.refershEnable = false;
		      } else {
		        this.refershEnable = true;
		      }
	    },
	}

子组件--监听状态变化，将当前弹框状态传值给父组件
 watch: {
    show_modal(newVal) {
      if (newVal != undefined) {
        this.$emit("getModal", newVal);
      }
    },
  },
