Extracting a Reusable Input

Merapihkan dan memisahkan code Input

Buat file baru di dalam folder Common dengan nama Input.jsx

import React from "react";

const Input = ({ name, label, value, onChange }) => {
    return (
        <>
            <div className="form-group">
                <label htmlFor={name}>{ label }</label>
                    <input
                        value={value}
                        onChange={onChange}
                        id={name} 
                        name={name}
                        type="text" 
                        className="form-control" 
                    />
            </div>
        </>
    )
}

export default Input;

Ubah file LoginForm.jsx

import React, { Component } from "react";
import Input from './Common/Input';

class LoginForm extends Component {
    state = {
        account : {
            username: '',
            password: ''
        }
    }

    handleSubmit = e => {
        e.preventDefault();

        // Call the server
        const username = this.username.current.value;
        console.log("submit")
    }

    handleChange = ({ currentTarget: input }) => {
        const account = {...this.state.account};
        account[input.name] = input.value;
        this.setState({ account });
    }

    render(){
        const { account } = this.state;
        return (
            <>
                <div>
                    <h1>Login</h1>
                    <form onSubmit={this.handleSubmit} >
                        <Input 
                            name="username"
                            value={account.username}
                            label="Username"
                            onChange={this.handleChange}
                        />
                        <Input 
                            name="password"
                            value={account.password}
                            label="Password"
                            onChange={this.handleChange}
                        />
                        <button className="btn btn-primary">Login</button>
                    </form>
                </div>
            </>
        )
    }
}

export default LoginForm
