uniapp 获取页面滚动高度。初步计算基层代码

<template>
  <scroll-view class="scroll-view" scroll-y @scroll="onPageScroll">
	<div class="one">one</div>
	<div class="two">two</div>
	<div class="three">three</div>
  </scroll-view>
</template>

<script>
export default {
  data() {
    return {
      scrollTop: 0 // 初始化滚动高度为0
    }
  },
  methods: {
    onPageScroll(event) {
		console.log(event);
		this.scrollTop = event.scrollTop // 更新页面滚动高度
    }
  }
}
</script>
<style lang="scss">
.scroll-view{
	@include size(750rpx,3000rpx);
	.one{
		@include size(750rpx,1000rpx);
		background-color: aqua;
	}
	.two{
		@include size(750rpx,1000rpx);
		background-color: red;
	}
	.three{
		@include size(750rpx,1000rpx);
		background-color: aqua;
	}
}
</style>
