javascript - Is it possible to change form data before sending it? -

i'd find generic method change data before sending forms. is, if have <form> contains <input> of type (class) , user press send button, i'd transform input value format arrive server in corrected format.

i know can set submit() handler process data, need generic solution setup mechanism on load on page forms , forgets (perhaps forms sent ajax, other use jquery.validate send, etc)

use jquery's select form elements: $('form') , register handler form submit event. this:

$('form').submit(function(e){     e.preventdefault()     var $this = $(this)     var formdata = $this.serialize()     // thing     var yourdata = transform(formdata)     $.ajax({        post: $this.attr('action'),        data: yourdata,        ...     }) })
