事件绑定:
import React from 'react';
import BodyChild from './bodychild';
import PropTypes from 'prop-types'; // 15.5版本后独立出新包
export default class BodyIndex extends React.Component{
constructor() {
super(); // 调用基类的所有初始化方法
this.state = {
name: 'xiaoming',
age: 20
}
}
changeAge(age) {
this.setState({
age: age
});
}
render(){
return (
页面的主体内容
{this.state.age}
)
}
}
子页面向父页面传递参数的方法:
parent:
import React from 'react';
import BodyChild from './bodychild';
import PropTypes from 'prop-types'; // 15.5版本后独立出新包
export default class BodyIndex extends React.Component{
constructor() {
super();
name: 'xiaoming',
age: 20
}
}
getbodychildData(event) {
this.setState({
age: event.target.value
})
}
render(){
return (
页面的主体内容
{this.state.age}
)
}
}
import React from 'react';
export default class BodyChild extends React.Component{
render(){
return (
bodychild 子页面
)
}
}
带参数父子组件通讯
父组件:
import React from 'react';
import { Link, withRouter } from 'react-router-dom';
import {
Table, Button, Row, Col,
Form, Select, Input, Icon,
Divider, Badge, Modal,
message, DatePicker
} from 'antd';
import { observer, inject } from 'mobx-react';
import * as mobx from 'mobx';
import Comment from './Comment';
@withRouter
@observer
class APIAuthority extends React.Component {
constructor(props) {
super(props);
// 评分组件绑定事件 通过变量绑定事件!!!
this.handleVar = this.handleOk.bind(this);
}
// 评分模态框确定按钮事件 子组件调用方法,带有参数 !!!
handleOk = ( values ) => {
console.log(values);
this.setState({
ModalText: 'The modal will be closed after two seconds',
confirmLoading: true,
});
setTimeout(() => {
this.setState({
visible: false,
confirmLoading: false,
});
}, 2000);
}
// 评论弹出窗取消事件
handleCancel = () => {
this.setState({
visible: false,
});
}
render() {
const { tabList, visible, confirmLoading, apiId } = this.state;
return (
);
}
}
export default APIAuthority;
子组件:
/*
* @component Comment
* @author linzehong
* @desc API管理-API权限列表-->评分弹出窗组件
*/
import React from 'react';
import { Modal, Button, Input, Rate, Row, Col, Form } from 'antd';
import utils from 'common/utils';
import styles from './Comment.scss';
const PREFIX = 'apicomment';
const cx = utils.classnames(PREFIX, styles);
const { TextArea } = Input;
const FormItem = Form.Item;
class Comment extends React.Component {
constructor(props) {
super(props);
}
// 确定按钮事件 !!!
onHandleOk = (e) => {
// 表单直接获取值,不用通过按钮
this.props.form.validateFields((errors, values) => {
if (errors) return;
// 传递参数,调用父组件方法 通过props调用父组件的方法 !!!
// 可以调用handleOk 是因为父组件绑定的handleVar变量等于handleOk方法
this.props.handleOk(values);
});
}
render() {
const { visible, confirmLoading, handleCancel } = this.props;
const { getFieldDecorator } = this.props.form;
return (
);
}
}
export default Form.create({})(Comment)
