ENTER to TAB redirect problem: submit form at the end of cycle

I'm using this jQuery function to jumping on "input" styled components of the form:

$('*').live("keydown", function(e) 
{    
  var inputs = $(this).parents("form").eq(0).find(".input:visible:enabled"); 
  var idx = inputs.index(this); 

  // ENTER IS PRESSED
  if (e.keyCode == 13) 
  { 
    if (idx == inputs.length - 1) 
    {
      inputs[idx + 1].select();
    } 
    else 
    {                           
      inputs[idx + 1].focus(); 
      inputs[idx + 1].select();
    }
    return false;
  }
  // TAB IS PRESSED
  if (e.keyCode == 9) 
  { 
    inputs[idx + 1].select();
    return false;
  }
});

and this components on the form (reduced code):

<h:inputText id="persId" tabindex="1" styleClass="input">
<h:selectOneMenu id="type" tabindex="1" styleClass="input">
<h:selectOneMenu id="no" tabindex="1" styleClass="input">
<h:commandButton type="submit" tabindex="2" id="btnSubmit" styleClass="btninput"/>

what I need is to jumping on 3 inputs and after that submit a form (using Enter). When I replace selectOneMenu by inputText, it works fine, but with selectOneMenu, it doesn´t.

TAB rotate all three components normally.

What am I doing wrong?

UPDATE: perhaps it would be enough to fire enter normally if (idx == inputs.length - 1), but I don´t know how..?

SOLVED: aha, it's simple, just add document.getElementById('food:btnSubm开发者_JAVA技巧it').click(); :)

I hope this isn't a page for the internet. It's not smart to interfere with browser default behaviour.

Have you tried just returning true instead of false if they were on the last input?

Solved: just fire submit button if appropriate conditions are performed

 .....
 if (e.keyCode == 13) 
 { 
   if (idx == inputs.length - 1) 
   {
     document.getElementById('formId:buttonId').click();
   }
 }
 .....
