我需要改进一个客户端的网站，并且在他们的行为中发现了一个奇怪的错误。Ajax动作被调用两次
当网络调用一个ajax动作时，它被调用两次。我在js调用和PHP动作代码中有断点，并且js运行一次（这很好），但是PHP运行了两次。
我不知道还有什么测试。
我测试过：
- 没有断开链接（网站图标，或CSS和JS资源等）
- 在调用其中的集体诉讼事件开始时，我刚
event.preventDefault(); - 在这一事件的结局，我说：
return false; - 在表单标签，我有这样的：
onsubmit="event.returnValue = false; return false;"
编辑：我有所有浏览器的这个问题。
编辑II：代码 控制器中的动作：
public function getMapOffers() {
$temporal = $this->getOffers('all');
return $temporal;
}
public function getOffers($offerType = 'all',$opciones=false) {
// loadModels
$this->loadModel('Offer');
$this->autoRender = false; // We don't render a view in this example
//$this->request->onlyAllow('ajax'); // No direct access via browser URL
$this->loadModel('Customer');
$customer = $this->Auth->user();
$customer['googleaddress'] = $this->Customer->getDetaultGoogleAddress($customer);
$latitude_customer = isset($customer['latitude']) ? $customer['latitude'] : 0;
$longitude_customer = isset($customer['longitude']) ? $customer['longitude'] : 0;
$data = array();
$options = array();
