如何在jQuery php中验证后在提交表单上禁用“锚点”

Question

I have a small problem, a form on submit is being validated then I am sending it but I need to disable my submit button onClick if validation is successfull here is my button code

 <button type="submit" class="btn btn-primary " id="submitBtn"><i class="fa fa-envelope"></i> Kişi Kayıt</button>

and here is my jQuery code

..... here is validation codes .....
submitHandler: function(form) {

$.ajax({
    url: 'plugin/clientIssues.php?tU=1',
    type: "POST",
    data: $('#userReg').serialize(),
    success: function(response) {
               alert(response); // show response from the php script.

               window.setTimeout('location.reload()', 300);
             }            
     });
    return false;
    $form.submit();
 }
});

Do you have any idea where I can put

$('#submitBtn').hide();

if the validation is correct and pressed on submit button ?

Answer 1

In your success function:

success: function(response) {
           alert(response); // show response from the php script.
           $('#submitBtn').hide();
           window.setTimeout('location.reload()', 300);
         }

Although I'd (personally) just disable the button:

success: function(response) {
           alert(response); // show response from the php script.
           $('#submitBtn').attr('disabled','true');
           window.setTimeout('location.reload()', 300);
         }
