ant-design 設置 DatePicker 默認值

1.代碼

render() {
  const { value } = this.props;

  return (
    <React.Fragment>
      {
        value ?
        <DatePicker
          value={moment(value, dateFormat)}
          onChange={this.onChange}
        /> :
        <DatePicker
          onChange={this.onChange}
        />
      }
    </React.Fragment>
  );
}

或者

render() {
  const { value } = this.props;

  return (
    <DatePicker
      value={value ? moment(value, dateFormat) : undefined}
      onChange={this.onChange}
      allowClear
    />
  );
}
