I need to check if the form has changed, ie if some input data has changed, etc. So that when you do submit , or leave the page, make some button click, or the menu is informed to the user that the data has been changed, and that have not yet been saved. I found this link , but I do not know if it is possible, I wanted it in any click that was not the submit of the page and had made the change the user was notified, to do this I have to call function in several places, or is there a function that makes this general in the form page?

 $('form').on('change paste', 'input, select, textarea', function(){
    $mudou=true;
});


$( "#mybutton" ).click(function() {

if ($mudou==true){

   var msj='Algo mudou no formulário, deseja envia-lo?';
   if (!confirm(msj)) { 
      return false;
   } else {
     $( "#form_name" ).submit();
   }
}  
  
});
