Ill created a non-jQuery version. So only pure Javascript; https://jsfiddle.net/mm0uctuv/2/

Javascript:

var inputs = document.querySelectorAll("input,select");
for (var i = 0 ; i < inputs.length; i++) {
   inputs[i].addEventListener("keypress", function(e){
      if (e.which == 13) {
         e.preventDefault();
         var nextInput = document.querySelectorAll('[tabIndex="' + (this.tabIndex + 1) + '"]');
         if (nextInput.length === 0) {
            nextInput = document.querySelectorAll('[tabIndex="1"]');
         }
         nextInput[0].focus();
      }
   })
}

HTML:

<form>
   Field 1: <input type="text" tabindex="1"><br>
   Field 3: <input type="text" tabindex="3"><br>
   Field 2: <input type="text" tabindex="2">
</form>
