微调提交表单时提交表格

我想添加一个微调框的提交按钮，当表单正在提交过程中。微调提交表单时提交表格

表单提交正常，但我无法让微调显示。请帮帮我。

(function() { 
 
    $(document).on("click", "#submitbutton", function (event) { 
 
     var elem = $(event.currentTarget); 
 
     elem.addClass('active'); 
 
     var formdata = $("#filterdata").serializeArray(); 
 
     var url1 = "/SelectUnit"; 
 
     $.ajax({url:"/echo/html", data: {delay:1}}).always(function(){ 
 
      elem.removeClass('active'); 
 
     }); 
 
    }); 
 
})();

.spinner { 
 
    opacity: 0; 
 
    display:none; 
 
    width: 20px; 
 
    height:10px; 
 
    -webkit-transition: opacity 0.25s, max-width 0.45s; 
 
    -moz-transition: opacity 0.25s, max-width 0.45s; 
 
    -o-transition: opacity 0.25s, max-width 0.45s; 
 
    transition: opacity 0.25s, max-width 0.45s; 
 
    /* Duration fixed since we animate additional hidden width */ 
 
} 
 
.has-spinner.active { 
 
    cursor:progress; 
 
} 
 
.has-spinner.active .spinner { 
 
    display:inline-block; 
 
    opacity: 1; 
 
    max-width: 50px; 
 
    /* More than it will ever come, notice that this affects on animation duration */ 
 
}

我曾用jQuery试图提交和许多其他片断我喜欢到目前为止没有成功。
