jQuery Ajax请求仅在移动浏览器中失败

Question

There are numerous posts where people ask this.. but it seems like the majority have issues when they use ajax requests for cross domain connection. I simply use this on the same domain and still cannot manage to get the ajax request to work on my mobile browser... it works perfectly on the desktop browser though.

This is the code I'm using:

Ajax Call

$.ajax({
    type: 'POST',
    url: '/test/Stores/storeCheck',
    data: $input,
    dataType: 'json',
    contentType: "application/x-www-form-urlencoded;charset=utf-8",
    success: function (data) {
      alert("success");
    },
    error:function (xhr) {
      alert("failed");
    }
});

PHP controller (cakephp)

function storeCheck () {

    if ($this->request->is('ajax')) {

        //Selecting values from the DB and returning them in $result

        $this->autoRender = false;
        return (json_encode($result));

    }

}

In my mobile browser the ajax request is made, and it just goes on until it reaches the error event showing me the failed alert popup. I've tried using JSONP as some suggested, but with no success. Any thoughts would be highly appreciated.

I managed to resolve this issue. I used echo instead of return in my controller function. I also turned of the Debug for my ajax request in the controller:

function storeCheck () {

if ($this->request->is('ajax')) {

    Configure::write('debug', 0);

    //Selecting values from the DB and returning them in $result

    $this->autoRender = false;
    echo json_encode($result);

}

}
