在Drupal自定义模块中点击3次后，Drupal禁用按钮

我是Drupal 的新手

我构建了类似于webform的自定义模块我的模块页面包含两个提交按钮和两个文本框，如下所示：

function contact_request($form, &$form_state) {
 $form ['info'] =array(   
    '#markup' => "<div id='pageRequestDiv'>",    
  );  
    $form['number'] = array(
    '#prefix' => '<div class="webform-container-inline2">',
    '#suffix' => '</div>',
    '#type' => 'textfield',
    '#title' => t('Number'),
    '#size' => 20,
    '#maxlength' => 255,
    '#attributes'=>array('class'=>array('txtli')),  
    '#required'=>true,
  );
  $form['send_vcode'] = array(
    '#prefix' => '<div style="margin-top:30px;">',
    '#suffix' => '</div><br/><br/>',
    '#type' => 'submit',
    '#value' => t('Send Verification Code'),
    '#ajax' => array(
       'callback' => 'send_Verification_code_callback',
       'wrapper' => 'ContactUsMsgDiv',          
       'method'=>'replace',
       'effect'=>'fade',
    ),        
  );
    $form['verification_code'] = array(
    '#prefix' => '<div class="webform-container-inline2">',
    '#suffix' => '</div>',
    '#type' => 'textfield',
    '#title' => t('Verification Code'),
    '#size' => 20,
    '#maxlength' => 255,
    '#attributes'=>array('class'=>array('txtli')),  
    '#required'=>true,
  );
 $form['sendmail'] = array(
    '#prefix' => '<div style="margin-top:30px;">',
    '#suffix' => '</div></div>',
    '#type' => 'submit',
    '#value' => t('Send Request'),
    '#ajax' => array(
       'callback' => 'get_contact_us_callback',
       'wrapper' => 'ContactUsMsgDiv',          
       'method'=>'replace',
       'effect'=>'fade',
    ),        
  );
  return $form;
}

用户输入号码，然后第一个按钮发送短信到手机，然后他在第二个文本框中键入短信，然后点击发送。

我想禁用用户点击3次后的第一个按钮。

我试过下面的JS，但它在一次点击后就禁用了两个按钮。我只想在点击3次后禁用第一个按钮

     Drupal.behaviors.hideSubmitButton = {
          attach: function(context) {
            $('form.node-form', context).once('hideSubmitButton', function () {
              var $form = $(this);
              $form.find('input.form-submit').click(function (e) {
                var el = $(this);
                el.after('<input type="hidden" name="' + el.attr('name') + '" value="' + el.attr('value') + '" />');
                return true;
              });
              $form.submit(function (e) {
                if (!e.isPropagationStopped()) {
                  $('input.form-submit', $(this)).attr('disabled', 'disabled');
                  return true;
                }  
              });
            });
          }
        };

更新代码：
函数send_Verification_code_callback（$form，&$form_state）{发送短信的一些代码return$form；}

function contact_us_request($form, &$form_state) {  
  $form['#prefix'] = '<div id="my-form-wrapper">';
  $form['#suffix'] = '</div>';
  $form ['info'] =array(   
    '#markup' => "<div id='pageAbiliRequestDiv'>",    
  );  
 $form['contact_number'] = array(
    '#prefix' => '<div class="webform-container-inline2">',
    '#suffix' => '</div>',
    '#type' => 'textfield',
    '#title' => t('Contact Number'),
    '#size' => 20,
    '#maxlength' => 255,
    '#attributes'=>array('class'=>array('txtabili')),   
    '#required'=>true,
  );
$form['verification_code'] = array(
    '#prefix' => '<div class="webform-container-inline2">',
    '#suffix' => '</div>',
    '#type' => 'textfield',
    '#title' => t('Verification Code'),
    '#size' => 20,
    '#maxlength' => 255,
    '#attributes'=>array('class'=>array('txtabili')),   
    '#required'=>true,
  );
  $form['send_vcode'] = array(
    '#prefix' => '<div style="margin-top:30px;">',
    '#suffix' => '</div><br/><br/>',
    '#type' => 'submit',
    '#value' => t('Send Verification Code'),
    '#ajax' => array(
       'callback' => 'send_Verification_code_callback',
       'wrapper' => 'my-form-wrapper',          
       'method'=>'replace',
       'effect'=>'fade',
    ),        
  );
  $form['sendmail'] = array(
    '#prefix' => '<div style="margin-top:30px;">',
    '#suffix' => '</div></div>',
    '#type' => 'submit',
    '#value' => t('Send Request'),
    '#ajax' => array(
       'callback' => 'get_contact_us_callback',
       'wrapper' => 'ContactUsMsgDiv',          
       'method'=>'replace',
       'effect'=>'fade',
    ),        
  );
  $form['clicks'] = array(
  '#type' => 'value',
);
if (isset($form_state['values']['clicks'])) {
  if ($form_state['values']['clicks'] == 3) {
    $form['send_vcode']['#disabled'] = TRUE;
  } else {
    $form['clicks']['#value'] = $form_state['values']['clicks'] + 1;
  }
} else {
    $form['clicks']['#value'] = 0;
}
