如何在 React 中触发 onBlur 事件?

How to fire onBlur event in React?

我有一个要在 onBlur 上格式化的输入字段值,我的代码如下所示:

组件:

  <Input
    onBlur={this.formatEndpoint}
  />

函数:

  formatEndpoint() {
    let endpoint = this.state.inputEndpoint;

    endpoint = endpoint.replace(/\s/g, '').replace(/\/+$/, '');

    if (endpoint.slice(-1) === '/') {
      endpoint = endpoint.substring(0, endpoint.length - 1);
    }

    console.log('anything');
  }

为什么 console.log() 对 Blur 不起作用?谢谢

多亏了评论,我才弄明白了。我必须像这样向 Input 添加一个 onBlur 道具:

export default class Input extends React.Component {
  constructor() {
    super();
    this.handleBlur = this.handleBlur.bind(this);
  }

  handleBlur() {
    const { onBlur } = this.props;
    onBlur();
  }

  render() {
    return <input onBlur={this.handleBlur} />
  }
}

Input.propTypes = {
  onBlur: PropTypes.func,
};

Input.defaultProps = {
  onBlur: () => {},
};

经过大量搜索,我用下面的代码做到了, 就我而言,我使用的是 React CS6。

class test extends React.Component {
  onBlur() {
    console.log('anything');
  }


   render () {
      let { onBlur, onChange, value, ...props } = this.props;

      return (
        <input onBlur={ this.onBlur }  />
      );
  }

}
