jquery - resume submit after event.preventDefault -

i'm trying achieve simple data-flow there must i'm not getting.

• i have table n rows.
• each row has own form submit button , hidden input.
• i want user click on button , prompt displayed.
• in prompt can insert date.
• after inserted date, hidden input value selected date , form submitted.

this code i'm using without success:

<td>     <form id="form_{{ document.id }}" class="form-fattura-saldata" action="my-file.php" method="post">         <input type="hidden" class="data-pagamento" name="data-pagamento" value="">         <button class="btn btn-default fattura_saldata" type="submit">saldata</button>     </form> </td> 

and jquery code:

var saldatafatturachange = function(event) {     event.preventdefault();     var prompt = bootbox.prompt("confermare la data di pagamento", function(result) {         if (result === null) {         } else {             $('.data-pagamento').val(result);         }     });     $('.bootbox-input').daterangepicker({         startdate: new date(),         format: 'dd/mm/yyyy',         singledatepicker: true     }); };  $('.form-fattura-saldata').each(function() {     $(this).on('submit', saldatafatturachange); }); 

the main problem can prevent submit action don't know how re-sumbit form. , don't know how assign value of hidden input of form after user has choose date.

any appreciated.

p.s. i'm using bootstrap, not relevant @ all.

that's how resolved question:

var saldatafatturachange = function(event) {     event.preventdefault();     var currenttarget = event.target;     var prompt = bootbox.prompt("confermare la data di pagamento", function(result) {         if (result === null) {         } else {             $(currenttarget).find('.data-pagamento').val(result);             currenttarget.submit();         }     });     $('.bootbox-input').daterangepicker({         startdate: new date(),         format: 'dd/mm/yyyy',         singledatepicker: true     }); };  $('.form-fattura-saldata').each(function() {     $(this).on('submit', saldatafatturachange); }); 

simply, event has event.target target of event fired. simple achieve.
