Jquery提交后如何禁用提交按钮？

Question

对我来说没有任何作用。我使用了给定的表格

<form method="post" id="mainform" class="form-horizontal" role="form" enctype='multipart/form-data' ><div class="col-lg-8 col-lg-push-1">            
                        <div class="form-actions">
                              <div class="row">
                                <div class="col-md-offset-4 col-md-9">
                                  <div class="button-group"> 
         <button type="submit" class="btn blue ss"  id="mainbutton"> Submit <i class="m-icon-swapright m-icon-white"></i></button>

         </div>
         </div>
         </div>
         </div>
      </div>
      </form> 

我的Jquery是

<script>
$('#mainform').submit(function(){ 

  $("#mainbutton").attr("disabled", true);

}）;

Answer 1

$("#mainbutton").click(function(){
    $(this).attr('disabled','');
}
