req,reqType,reqMessage: tömbök, azonos hosszúságúak
---
req: vizsgálandó elemek ID-je
reqType: 'text','email','numeric','date','radio','checkbox' vagy Regexp. Ha nincs megadva akkor 'text' szerint ellenőrzi
reqMessage: 'Mi jelenjen meg'. Ha hash(#) karakter közé rakod, csak az jelenik meg.
pl:
function checkCallbackForm() {
  var req = new Array('name','phone','email','prefer','message');
  var reqType = new Array('text','text','email','text','text');
  var reqMessage = new Array('Name','Phone Number','E-mail','Prefered time to get contacted','Message');
  return checkInputs(req,reqType,reqMessage);
}
