<p> Let's suppose we have the following React component containing a <code>form</code>: </p> <pre> const Foo = () => { return ( <form onSubmit={handleSubmit}> <input type="email" name="email" defaultValue="foo@bar.co
一.关于react中from表单中getFieldsValue,getFieldValue,validateFields,resetFields,getFieldDecorator,initialvalue的用法 1import React from 'react';2import { Card, Row, Col, Form, DatePicker, Select, Button, Checkbox, Table, Switch, message, Pagination, Input } from 'antd';3const { Option } =Select...

最熟悉的陌生人 rc-form “我们都知道 React 框架设计模式和 Vue 不同,Vue 中作者已经帮我们实现了数据的双向绑定,数据驱动视图,视图驱动数据的改变,但是 React 中需要我们手动调用 setState 实现数据驱动视图的改变...为了避免这种情况发生,或者如果仅是为了我们自己的职业生涯规划,使自己更上一层楼的话也是有必要...

export default Form.create()(MedicalListModal); 子组件 EasyAutoComplete.jsx render() { const { dataSource } = this.state; const { data, getFieldDecorator, dataIndex } = this.props; let _id = data.id ? data.id : dataIndex; let initialValue = data[dataIndex] ? data[dataIndex] '' : ...
Form.create()(Questionary) // 用Form.create()加一层 2. 坑二 报错:'form' is missing in props validation react/prop-types 原因: 加了代码检查工具eslint 解决办法: 第一步: import PropTypes from 'prop-types'; 第二步: form: PropTypes.any ...
</form> ); } } 2.1 非受控组件 刚说到受控组件所有的状态都由外界接管,非受控组件则恰恰相反,它将状态存储在自身内部,我们可以借用 React 中的 ref 来访问它。同样还是官方的例子: class NameForm extends React.Component { constructor(props) {
