javascript 一般表单事件监听器直接字段，对象属性

Posted 2021-05-03

// form event field
onFieldChange = e => {
    this.setState({ [e.target.name]: e.target.value });
  };

// form event Object property
  onPropertyChange = e => {
    this.setState({
      [e.target.dataset.model]: {
        ...this.state[e.target.dataset.model],
        [e.target.name]: e.target.value
      }
    });
  };
