react简书项目学习笔记38如何拿到页面的输入值

通过ref属性把输入值存起来，然后在函数中传参

//存值
<Input placeholder='密码' type='password' ref={(input) => { this.password = input }}>
</Input>

//传参
<Button placeholder='登陆' onClick={() => this.props.login(this.account, this.password)}>
</Button>

const mapDispatch = (dispatch) => ({
login(accountEle, passwordEle) {
console.log(accountEle)
console.log(accountEle.value)
}
})
