react开发小TIPS:登录表单的简单应用。
代码如下:
import React from 'react'; import { Input, Button, message } from "antd"; import { UserOutlined, LockOutlined, EyeInvisibleOutlined, EyeTwoTone } from '@ant-design/icons'; import './index.less' class Login extends React.Component{ constructor(props) { super(props) this.state = { username: '', password: '' } }; submit=()=>{ if (this.state.username !== '' && this.state.password !== '') { this.props.history.push('/Index') } else { message.error("用户名和密码不能为空") } }; user_change=(e)=>{ this.setState({ username: e.target.value }) } password_change=(e)=>{ this.setState({ password: e.target.value }) } render () { const {username, password} = this.state return ( <div className="login"> <Input value={username} onChange={this.user_change} size="large" placeholder="用户名" prefix={<UserOutlined />} /> <Input.Password value={password} onChange={this.password_change} size="large" className="login__input" placeholder="密码" prefix={<LockOutlined />} iconRender={visible => (visible ? <EyeTwoTone /> : <EyeInvisibleOutlined />)} /> <Button className="login__btn" size="large" type="primary" onClick={this.submit} > 登录 </Button> </div> ); } } export default Login;
放到编辑器里试试吧!!!
