How to remove contact form spinning icon?

Hello,

On submit the spinning icon appears and my my controller program take over , and save the data.

But the problem is , the spinning icon still shows , how to hide it?

I don't want to use sendmail.php but hope to handle it myself, because I want to save the data into database but not just mail.

Hello,

Anybody there??
I want to use Laravel(PHP Framework) to handle form post but not sendmail.php .

Below is the controller code:

public function store(Request $request)
    {
        $contact = Contact::create($request->all());
        if (isset($contact)) {
            return redirect('class/signUp');
            // return echo { "alert": "success", "message": "Success" };
        }else{
            // return echo "fail";
        }
        return redirect('class/signUp');
    }

Please give me some clue , thanks~

I found that the contact info seems not store into the database, and that means my controller method isn't called..

Hello,

In the end , I found the problem and fix it , thanks for your help.
In my case , I have to use return rather than echo , I don't know why actually.

return array('alert' => "success" , 'message' => '聯絡訊息已送出，感謝您' );

Anyway, thanks for your help.
