taro中子父传值
其實網上很多方法,我這只是一個簡單的demo,廢話不多說直接上代碼
import Taro, { Component } from '@tarojs/taro' import { View, Text } from '@tarojs/components' import './index.less'//子組件 class Child extends Component{constructor(props) {super(props);this.state = ({})}handleVal (event) {this.props.handleEmail(event.target.value);}render (){return (<div>請輸入郵箱:<input style="width:200px;height:30px;font-size:18px;" ref="emailDom" onChange={this.handleVal.bind(this)} /></div>)} };export default class Index extends Component {constructor(props) {super(props);this.state = {email:"火星黑洞"}}handleEmail1(date){this.setState({email:date})}config = {navigationBarTitleText: '首頁'}componentWillMount () { }componentDidMount () { }componentWillUnmount () { }componentDidShow () { }componentDidHide () { }render () {return (<div className='index'><h3>子父傳值</h3><Child name="email" handleEmail={this.handleEmail1.bind(this)}/><div>用戶郵箱:{this.state.email}</div></div>)} }然后執行:cnpm run dev:h5
頁面效果是:
