uniapp微信小程序动态更新scroll-view标签的高度_uniapp 获取组件scrollheight

onReady() {
      //精确动态计算轮播图高度
      //自定义tabbar获取方法
	  uni.getSystemInfo({
		    success: res => {
				const query = uni.createSelectorQuery()
				query.select('.tabbars').boundingClientRect()
				query.exec(res1 => {
					this.scrollheight = res.windowHeight - res.statusBarHeight - uni.upx2px(88) - res1[0].height;
				})
		
			}
		})
      //原生tabbar写法
      uni.getSystemInfo({
		    success: res => {
				this.scrollheight = res.windowHeight - res.statusBarHeight- uni.upx2px(88);
			}
		})
	},

获取了之后在scroll-view标签上动态赋值高度即可

<scroll-view :scroll-top="scrollTops" scroll-y="true" :style="'height:'+scollHeight+'px'">
    <view>
        
    </view>
</scroll-view>
