問題描述

react 里使用antd model 怎么控制model 開關

父主鍵組件 傳入屬性

<AdvSimpleInfo visible={this.state.advSimpleInfoModel.visible}/>

advSimpleInfoModel 父組件state對象

advSimpleInfoModel: { visible: false }

子主鍵

import React from ’react’;import { Modal} from ’antd’;import Common from ’pricomp/Common’;import ’./advSimpleInfo.less’export default class AdvSimpleInfo extends React.Component { constructor(props) { super(props); this.state = { confirmLoading: false }; } showModal() { this.setState({ visible: true }); } handleOk() { let _this = this; this.setState({ Loading: true }); let params = { advertId: this.props.id }; const promise = Common.ajax(’pageQueryPrivilege’, params); promise.then(function(res) { console.log(res); }) } render() { return ( <p><Modal visible={this.props.visible} onOk={this.handleOk} confirmLoading={this.state.confirmLoading} onCancel={this.handleCancel}> <p>{this.state.ModalText}</p> <p className='adv-simple-info-warp'> <p><span>ID:</span>88888</p> <p><span>名稱:</span>一個200紅包</p> <p><span>狀態(tài):</span>有效</p> <p><span>庫存:</span>剩余/總數(shù)</p> <p><span>廣告主:</span>剩余/總數(shù)</p> <p><span>代理商:</span>剩余/總數(shù)</p> </p></Modal> </p> ); }}

子組件屬性 改變了傳入的值 可是彈窗不能出現(xiàn)

visible={this.props.visible}

問題解答

看不到改變state里面的visible的方法呀。不夠詳細唉。

state 和 props 傻傻分不清，你的showModal這個方法也沒有綁定this，好好看看官網(wǎng)的例子：

import { Modal, Button } from ’antd’;class App extends React.Component { state = { visible: false } showModal = () => { this.setState({ visible: true, }); } handleOk = (e) => { console.log(e); this.setState({ visible: false, }); } handleCancel = (e) => { console.log(e); this.setState({ visible: false, }); } render() { return ( <p><Button type='primary' onClick={this.showModal}>Open</Button><Modal visible={this.state.visible} onOk={this.handleOk} onCancel={this.handleCancel}> <p>Some contents...</p> <p>Some contents...</p> <p>Some contents...</p></Modal> </p> ); }}ReactDOM.render(<App />, mountNode);
