React加Ant Design实现的一个登陆界面及小案例

如果你没有安装过react脚手架的就需要先安装：

在cmd输入命令安装：

可以在cmd输入create-react-app 项目名称    来创建一个react项目

建好后在输入命令：npm install antd --save 来下载安装ant Design框架

然后就可以输入命令：npm start 来启动运行项目了

在HBuilder里导入打开该项目（目录结构如下）：

具体实现代码如下：

App.js代码

import React, { Component } from 'react';


import MyMain from './MyMain';
class App extends Component {
  render() {
    return (
      <div>
        <MyMain></MyMain>
       
      </div>
    );
  }
}

export default App;

index.js代码
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import MyMain from './MyMain';
import { Form, Icon, Input, Button, Checkbox } from 'antd';

const WrappedNormalLoginForm = Form.create()(MyMain);
ReactDOM.render(<WrappedNormalLoginForm />, document.getElementById('root'));

MyMain.js代码：
import React, { Component } from 'react';
import 'antd/dist/antd.css';
import { Form, Icon, Input, Button, Checkbox } from 'antd';
import './index.css';

const FormItem = Form.Item;


class MyMain extends React.Component {
  handleSubmit = (e) => {
    e.preventDefault();
    this.props.form.validateFields((err, values) => {
      if (!err) {
        console.log('Received values of form: ', values);
      }
    });
  }
  render() {
    const { getFieldDecorator } = this.props.form;
    return (
      <Form onSubmit={this.handleSubmit} className="login-form">
        <FormItem>
          {getFieldDecorator('userName', {
            rules: [{ required: true, message: 'Please input your username!' }],
          })(
            <Input prefix={<Icon type="user" style={{ color: 'rgba(0,0,0,.25)' }} />} placeholder="Username" />
          )}
        </FormItem>
        <FormItem>
          {getFieldDecorator('password', {
            rules: [{ required: true, message: 'Please input your Password!' }],
          })(
            <Input prefix={<Icon type="lock" style={{ color: 'rgba(0,0,0,.25)' }} />} type="password" placeholder="Password" />
          )}
        </FormItem>
        <FormItem>
          {getFieldDecorator('remember', {
            valuePropName: 'checked',
            initialValue: true,
          })(
            <Checkbox>Remember me</Checkbox>
          )}
          <a className="login-form-forgot" href="">Forgot password</a>
          <Button type="primary" htmlType="submit" className="login-form-button">
            Log in
          </Button>
          Or <a href="">register now!</a>
        </FormItem>
      </Form>
    );
  }
}

export default MyMain;
