Reactjs Basic Tutorials


Friends now I proceed onwards and here is the working code snippet for Reactjs Modal Popup Register Form with Validations and please use this carefully to avoid the mistakes:

1. Firstly friends we need fresh reactjs setup and for that we need to run below commands into our terminal and also w should have latest node version installed on our system:

npx create-react-app reactjsappendfields

cd reactjsappendfields

npm start // run the project

 

2. Now we need to run below commands to get bootstrap(for good layout), antd(for modal and form) modules into our react js app:

npm install antd

npm install bootstrap --save

npm start

 

3. Now friends, after are done with commands, now please open reactjsappendfields/src/App.js file and add below code inside it:

import React from 'react';

import './App.css';

//Bootstrap and jQuery libraries
import 'bootstrap/dist/css/bootstrap.min.css';

//Incude antd modules, icon and style
import { Form, Input, Button, Space } from 'antd';
import { MinusCircleOutlined, PlusOutlined } from '@ant-design/icons';
import "antd/dist/antd.css";



class App extends React.Component {

  
  render(){
    const Demo = () => {
      const onFinish = values => {
        //Here will get form values
        console.log('Received values of form:', values);
      };
    
      return (
        <Form name="dynamic_form_nest_item" onFinish={onFinish} autoComplete="off">
          <Form.List name="users">
            {(fields, { add, remove }) => (
              <>
                {fields.map(field => (
                  <Space key={field.key} style={{ display: 'flex', marginBottom: 8 }} align="baseline">
                    <Form.Item
                      {...field}
                      name={[field.name, 'first']}
                      fieldKey={[field.fieldKey, 'first']}
                      rules={[{ required: true, message: 'Missing first name' }]}
                    >
                      <Input placeholder="First Name" />
                    </Form.Item>
                    <Form.Item
                      {...field}
                      name={[field.name, 'last']}
                      fieldKey={[field.fieldKey, 'last']}
                      rules={[{ required: true, message: 'Missing last name' }]}
                    >
                      <Input placeholder="Last Name" />
                    </Form.Item>
                    <MinusCircleOutlined onClick={() => remove(field.name)} />
                  </Space>
                ))}
                <Form.Item>
                  <Button type="dashed" onClick={() => add()} block icon={<PlusOutlined />}>
                    Add field
                  </Button>
                </Form.Item>
              </>
            )}
          </Form.List>
          <Form.Item>
            <Button type="primary" htmlType="submit">
              Submit
            </Button>
          </Form.Item>
        </Form>
      );
    };
  return (
    <div className="MainDiv">
      <div className="jumbotron text-center">
          <h3>Therichpost.com<br>
      </div>
      
      <div className="container">
          
      <Demo />
        </div>
      </div>
  );
}

}
export default App;
