uniapp中scroll-view利用scroll-into-view实现锚点功能

<template>
	<view class="content">
		<scroll-view scroll-y="true" :scroll-into-view="intoindex" style="height: 300px;">
			<view v-for="(item,index) in content" :key='index' :id='"text"+index'>{{item+index}}</view>
		</scroll-view>
		<button type="primary" @tap="scroll">跳</button>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				content: ["珍珠奶茶", "鲜百香双响炮", "奶茶三兄弟", "珍珠奶茶", "鲜百香双响炮", "奶茶三兄弟", "珍珠奶茶", "鲜百香双响炮", "奶茶三兄弟", "珍珠奶茶", "鲜百香双响炮",

				],
				intoindex: '',
				num:10 //动态模拟需要跳到的位置
			}

		onLoad() {

		methods: {
			scroll() {
				this.num+=3
				this.$nextTick(()=> {

					console.log(this.intoindex)

				this.intoindex=''  //不清空再次跳到锚点位置会不起作用
