问题描述 将目标组件放入到 某个组件的children里面无法触发函数创建 ref 如下
复现步骤
import Taro, { Component } from '@tarojs/taro' import { View, Swiper, SwiperItem } from '@tarojs/components' class PaperCreate extends Component { refQues = node => { this.questionRefs = this.questionRefs || [] this.questionRefs.push(node) console.log(node) } render() { return ( <View className='page-create-wrapper'> <Swiper className='page-create-content' indicatorDots > <SwiperItem> <View className='swiper-content'> <QuesStart /* 这里是OK的 */ ref={this.refQues} edit {...base} onSubmit={this.onSubmitStart.bind(this)} /> </View> </SwiperItem> {questions.map((item, index) => ( /* 这里是OK的 */ <SwiperItem key={item.qkey} ref={this.refQues}> <QuesType edit {...item} number={index + 1} /********* 这个地方不会触发 **********/ ref={this.refQues} onSubmit={this.onSubmitQuestion.bind(this)} /> </SwiperItem> ))} </Swiper> </View> ) } } export default PaperCreate
期望行为 可以触发ref函数
报错信息
系统信息

taro info
补充信息 {questions.map((item, index) => {})} 外面有一层循环, 是这个引起的??
