Please refer : Jquery : Ajax : How can I show loading dialog before start and close after close?

I hope this could help you

$("div.add_post a").click(function(){

  var dlg = loadingDialog({modal : true, minHeight : 80, show : true});
            dlg.dialog("show");
  $.ajax({
        url : "/add.php",
        complete : function (){
            dlg.dialog("hide");
        }
     });
 return false;
});


//--Loading dialog

function loadingDialog(dOpts, text = "пожалуйста подождите, идет загрузка...")
{
    var dlg = $("
 "+text+"
").dialog(dOpts);
    $(".ui-dialog-titlebar").hide();

    return dialog;
}
