我在 Drupal 8 中编写了一个自定义模块,该模块具有与 Paymetric 的 javascript 集成。我正在使用 javascript 处理此表单的提交,但问题是,它会触发表单验证,但从不提交表单。另一方面,当我使用表单的自定义 drupal 提交按钮提交它时,它可以正常运行。我在我的几个其他模块中使用 javascript 处理表单提交,没有任何问题。有人可以帮我找出为什么会发生这种情况吗?
检查是否有任何隐藏字段是必需的并限制我们提交表单,还检查了控制台中的任何 javascript 错误,如果这可能以任何方式影响,我将在表单构建和构造时终止缓存。还确保提取并提交具有正确 ID 的表格。
这是我的代码:
Custom Module File:
/*
-- namespace defined and Drupal/Symphony classes used --
*/
class PurchaseCartContact extends FormBase {
protected $account;
protected $tempStore;
protected $messenger;
public function __construct(
AccountInterface $account,
PrivateTempStoreFactory $tempStore,
MessengerInterface $messenger
) {
\Drupal::service('page_cache_kill_switch')->trigger();
$this->account = $account;
$this->tempStore = $tempStore->get('org_purchases');
$this->messenger = $messenger;
}
public static function create(ContainerInterface $container) {
return new static(
$container->get('current_user'),
$container->get('tempstore.private'),
$container->get('messenger')
);
}
public function getFormId() {
return 'purchase_cart_contact';
}
public function buildForm(array $form, FormStateInterface $form_state) {
//$form = array();
$form['#cache']['max-age'] = 0;
$tempstore = \Drupal::service('tempstore.private')->get('org_purchases');
// custom logic and form fields defined
$form['submit'] = array(
'#type' => 'submit',
'#value' => $this->t('Submit'),
'#attributes' => [
'class' => ['btn btn-primary payment-submit'],
],
'#prefix' => '<div class="form-item">',
'#suffix' => '</div>',
);
return $form;
} // buildForm ends here
public function validateForm(array &$form, FormStateInterface $form_state) {
ksm("inside validate");
}
public function submitForm(array &$form, FormStateInterface $form_state) {
ksm("inside submit");
}
}
树枝文件:
<div id="action-nav" class="button-group form-item element">
{# <div class="pull-left"> {{ form.submit }} </div> #} {# works as expected #}
<div class="btn btn-primary" style="width: 150px;" id="edit-submitpurchasepayment">SUBMIT</div>
</div>
{{ form.form_token}}
{{ form.form_build_id }}
{{ form.form_id }}
Javascript 文件:
(function ($, Drupal) {
Drupal.behaviors.org_purchase = {
attach: function (context, settings) {
form = document.getElementById('purchase-cart-contact');
form.submit();
}
};
})(jQuery, Drupal);
