                                component={DateInput}
                                formitemlayout={formItemLayout}
                                value={this.state.setFieldValue}

          htmlType="submit">Submit</Button>

回答1:

Your Datepicker is not a controlled component. I converted it to a controlled component and date field was reset post form submission.

<DatePicker
  onChange={(date, dateString) =>
    setFieldValue("dateofbirth", dateString)
  }
  value={dateofbirth !== "" ? moment(dateofbirth) : ""}
/>

Instead of adding empty strings as it raises a propType error its best to use null

<DatePicker
  onChange={(date, dateString) =>
    setFieldValue("dateofbirth", dateString)
  }
  value={dateofbirth !== "" ? moment(dateofbirth) : null}
/>
