思路：利用 scroll-view元素的 scroll-into-view属性定位

<template>
    <u-form
    class="u-flex-col u-flex-1"
    :model="data.submit"
    ref="uFormSubmit1" 
    :errorType="['toast','message']" 
    @touchmove.stop.prevent="() => {}">
    <view class="page u-flex-col">

        <u-navbar back-text="返回" title="剑未配妥，出门已是江湖"></u-navbar>

        <scroll-view scroll-y class="u-flex-1 u-flex-col" @touchmove.stop="() => {}"
        :scroll-into-view="data.scrollIntoView">
            <view class="scroll-content u-flex-1">
            <!-- 防止无法提交上一步下一步 -->
            <u-form-item v-show="false" prop="submit"></u-form-item>
            <view class="operation-box">
                <u-form-item
                class="u-relative u-flex-1" 
                label-width="150" 
                label-position="left" 
                :label="'姓名'+item" 
                :key="index"
                :id="'u-form-item'+index"
                v-for="(item,index) in ['first',32,3,3,3,33,3,3,3,6,6,66,6,6,6,6,6,6,6,6,6,,66,6,6,6,6,6,6,'last']"
                required
                >
                    
                    <u-input

                    placeholder="请输入姓名"/>
                    <u-icon v-if="false" class="u-absolute" name="minus-circle-fill" color="#c0c4cc" size="68" style="cursor: pointer;right: 4px;"></u-icon>
                
                </u-form-item>
            </view>
            </view>
        </scroll-view>
        <view class="footer u-flex u-row-between">
            <text class="u-flex-1">提交</text>
        </view>
