实际发生的情况是，在执行 ajax 回调后，form_state 仍然有用户提交的值，而这不应该。如果有人知道我在这里做错了什么，请帮忙。
这有点老，但也许可以帮助别人 :)。
首先 - 你不能在 ajax 回调中修改 $form_state - 所以 $form_state->setRebuid() 不会有效果。
如 AJAX form docs 中所述，您应该只 return 标记、可渲染数组或 AjaxCommand。
这里需要做的是修改ajax回调中元素的值，更像这样：
function getAwardSlots(array &$form, FormStateInterface $form_state){
$date = $form_state->getValue('date')
$form['package']['award_slot']['#options'] = $this->getAwardSlotOptions($date);
return $form['package']['award_slot'];
}

我也为这个表格创建了一个模板

实际发生的情况是，在执行 ajax 回调后，form_state 仍然有用户提交的值，而这不应该。如果有人知道我在这里做错了什么，请帮忙。
这有点老，但也许可以帮助别人 :)。
首先 - 你不能在 ajax 回调中修改 $form_state - 所以 $form_state->setRebuid() 不会有效果。
如 AJAX form docs 中所述，您应该只 return 标记、可渲染数组或 AjaxCommand。
这里需要做的是修改ajax回调中元素的值，更像这样：
function getAwardSlots(array &$form, FormStateInterface $form_state){
$date = $form_state->getValue('date')
$form['package']['award_slot']['#options'] = $this->getAwardSlotOptions($date);
return $form['package']['award_slot'];
}
