Tabindex based on input key, getting form elements not working in jQuery

I have a form, and I can get all the elements of the form through serializeArray(). I want focus()over form elements based on their tabindex value using the enter key. Only if it matters in it or focus on yourself.

A bit new for jQuery, so if any errors ...

$.fn.entertab = function()
  {

 var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
  var maxTabIndex = 20;
        var elements = this.serializeArray();
     $.each(elements, function(i, element)
        {

 this.keypress(function(e){ 
    var nTabIndex=this.tabIndex;
       var myNode=this.nodeName.toLowerCase();
            if(nTabIndex > 0 && key == 13 && nTabIndex <= maxTabIndex && ((!myNode.attr("disabled")) || (myNode.val == "")))
      {
   myNode.focus(); 
   }
   else
   {
   nTabIndex=this.tabIndex+1;
      myNode.focus();
   }
   });

     });
        }
  $("theform").entertab();

You can also try HTML

<input id="122" class='TabOnEnter' tabindex="1" /><br>
<input id="123" class='TabOnEnter' tabindex="2" /><br>
<input id="124" class='TabOnEnter' tabindex="4" />This input is hidden<br>
<input id="124" class='TabOnEnter' tabindex="5" /><br>
<input id="125" class='TabOnEnter' tabindex="3" /><br>
<textarea class='TabOnEnter' tabindex="6">Hi, I am a test area</textarea>

SCRIPT ///////////

$(document).on("keypress", ".TabOnEnter" , function(e)
  {
    //Only do something when the user presses enter
    if( e.keyCode ==  13 )
    {
       var nextElement = $('[tabindex="' + (this.tabIndex+1)  + '"]');
       console.log( this , nextElement ); 
       if(nextElement.length )
         nextElement.focus()
       else
         $('[tabindex="1"]').focus();  
    }   
  });

//Hidden inputs should get their tabindex fixed, not in scope ;)
//$(function(){ $('input[tabindex="4"]').fadeOut();  })

////////////// Worked perfectly in EI, Chrome, Mozilla. not verified in safari and other browser

I think I understand what you want to do. I rewrote your code and ended up with this:

(function($){

    $.fn.entertab = function(options) {

        var defaults = {
            maxTabIndex: 20
        };

        options = $.extend({}, defaults, options);

        return this.filter('form').each(function(){

            var $this = $(this),
                $elms = $this.find("[tabindex]");

            $elms.each(function(){
                var $elm = $(this),
                    idx = parseInt($elm.attr("tabindex"));
                if (idx > options.maxTabIndex) {
                    return;
                }
                $elm.keydown(function(e){
                    if (e.which == 13 && ($elm.val() != '')) {
                        $elms.filter("[tabindex="+(idx+1)+"]").focus();
                        e.preventDefault();
                    }
                });
            });
        });
    };

})(jQuery);

jsFiddle.
