reactjs – React Controlled与Uncontrolled输入

我按照React Form教程创建了以下组件：

export default class SignInForm extends React.Component {
  constructor(props) {
    super(props)

    this.state = {
      email: '',password: ''
    }

    this.onEmailChange = this.onEmailChange.bind(this)
    this.onPasswordChange = this.onPasswordChange.bind(this)
  }

  onEmailChange(event) {
    this.setState({email: event.target.value})
  }

  onPasswordChange(password) {
    this.setState({password: event.target.value})
  }

  render() {
    return (
      <form onSubmit={this.props.handleSubmit}>
        <div>
          <label>Email</label>
          <div>
            <input type="email"
              placeholder="[email protected]"
              onChange={this.onEmailChange}
              value={this.state.email}
            />
          </div>
        </div>
        <div>
          <label>Password</label>
          <div>
            <input type="password"
              placeholder="Password"
              onChange={this.onPasswordChange}
              value={this.state.password}
            />
          </div>
        </div>
        <button type="submit" class="btn btn-primary">Submit</button>
      </form>
    )
  }
}

表单呈现后,我收到以下错误：

SignInForm is changing a controlled input of type password to be
uncontrolled. Input elements should not switch from controlled to
uncontrolled (or vice versa). Decide between using a controlled or
uncontrolled input element for the lifetime of the component

我找不到我把它变成一个不受控制的组件的地方.我究竟做错了什么？

看起来你的onPasswordChange方法应该是：

onPasswordChange(event) {
    this.setState({password: event.target.value})
}
