使用redux-form和materialUI为TimePicker设置defaultValue？

Question

我不能让设置defaultValue的任何版本（或defaultTime甚至只是value）从状态Redux的形式初始化TimePicker工作。所有其他字段填充正确，但日期/时间选择器不响应任何内容。帮助是muuuuch赞赏！

现在可以通过格式= {空}以时间和日期选择器。看到这里线程/关闭的问题：https://github.com/erikras/redux-form-material-ui/issues/37 ，可以查看这里开始鸣叫：https://twitter.com/megkadams/status/804363887428665345并继续在这里：https://twitter.com/megkadams/status/804369699693793280

<Field 
     name={`${service}.from_time`} 
     component={TimePicker} 
     format={(value, name) => { 
     if (fromTime) { 
      return value === '' ? null : new Date(fromTime) 
     } else { 
      return null; 
     } 
     }} 
     defaultValue={null} 
     pedantic 
     floatingLabelText="From" 
     className="textfield" 
    /> 

Answer 2

要设置默认时间TimePicker的：

<TimePicker hintText="Pick your time" defaultTime={new Date(2007, 11, 5, 8, 23, 17)} /> 

这里是一个工作的jsfiddle：https://jsfiddle.net/mu5r94m6/2/

Answer 3

您使用this.props.pantry...您renderGroups()内。

你需要bind，其功能是能够使用this

添加constructor到类和该函数使用bind

constructor(props) { 
    super(props); 
    this.renderGroups = this.renderGroups.bind(this); 
}
