多个表单提交的优化方案

1.问题

import React from 'react';
import './index.scss';


class Login extends React.Component {
	constructor(props) {
		super(props);
		this.state = {
			username: '',
			password: ''
		}
	}

	//用户名发生改变
	onUserNameChange(e) {
		console.log(e.target.value);
		this.setState({
			username: e.target.value
		})
	}

	//密码发生改变
	onPwdChange(e) {
		console.log(e.target.value);
		this.setState({
			password: e.target.value
		})
	}

	render() {
		return (
			<div className="col-md-4 col-md-offset-4">
				<div className="panel panel-default login-panel">
					<div className="panel-heading">欢迎登录MMALL后台管理系统</div>
					<div className="panel-body">
						<form>
							<div className="form-group">
								<input type="text" className="form-control" placeholder="请输入用户名"
											 onChange={e => this.onUserNameChange(e)}/>
							</div>
							<div className="form-group">
								<input type="password" className="form-control" placeholder="请输入密码"
											 onChange={e => this.onPwdChange(e)}/>
							</div>
							<button type="submit" className="btn btn-lg btn-block btn-primary">登录</button>
						</form>
					</div>
				</div>
			</div>

		)
	}
}

export default Login;

2.解决：一个函数写所有的input值的提交

import React from 'react';
import './index.scss';


class Login extends React.Component {
	constructor(props) {
		super(props);
		this.state = {
			username: '',
			password: ''
		}
	}

	//用户名发生改变
	onInputChange(e) {
		let inputName = e.target.name,
			inputValue = e.target.value;
		console.log(inputName, inputValue);

		this.setState({
			[inputName]: inputValue
		})
	}

	render() {
		return (
			<div className="col-md-4 col-md-offset-4">
				<div className="panel panel-default login-panel">
					<div className="panel-heading">欢迎登录MMALL后台管理系统</div>
					<div className="panel-body">
						<form>
							<div className="form-group">
								<input type="text"
											 className="form-control"
											 placeholder="请输入用户名"
											 name='username'
											 onChange={e => this.onInputChange(e)}/>
							</div>
							<div className="form-group">
								<input type="password"
											 className="form-control"
											 placeholder="请输入密码"
											 name='password'
											 onChange={e => this.onInputChange(e)}/>
							</div>
							<button type="submit" className="btn btn-lg btn-block btn-primary">登录</button>
						</form>
					</div>
				</div>
			</div>

		)
	}
}

export default Login;
