其实就是标签选择器 获取到对应标签所在的高度，然后用uni.pageScrollTo跳转，这是在正常页面上的跳转，scroll-view中更方便

<template>
	<view class="product-page">
		<scroll-view scroll-y="true" class="scroll-view">
			商品详情内容区域
			<view class="product-details">
				商品详情内容
			</view>
			点评内容区域
			<view class="product-reviews">
				点评内容
			</view>
		</scroll-view>
		<view class="tabs">
			<view class="tab" @click="scrollToDetails">详情</view>
			<view class="tab" @click="scrollToReviews">点评</view>
		</view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				// 可以添加其他数据属性
			};
		},
		methods: {
			scrollToDetails() {
				uni.pageScrollTo({
					scrollTop: 0,
					duration: 300
				});
			},
			scrollToReviews() {
				uni.createSelectorQuery().select('.product-reviews').boundingClientRect((rect) => {
					console.log(rect.top)
					if (rect) {
						uni.pageScrollTo({
							scrollTop: rect.top,
							duration: 300
						});
					}
				}).exec();
			}
		}
	};
</script>

<style lang="scss">
	.product-page {
		position: relative;
	}

	.scroll-view {
		height: 100vh;
	}

	.product-details {

	.product-reviews {
