Disabling Enter Causing Submit with jQuery

Recently I was asked to disable the submit event being triggered when the enter key is hit in a textbox input. This is for an ASP.NET MVC application. That means that including this in the site.master will allow identical behaviour across the entire web application.

When you hit enter, the focus will move to the next textbox.

There is also browser sensing code since Firefox needs a different event bound.


jQuery(document).ready(function($) {
   textboxes = $("input:text");

   if ($.browser.mozilla) {
      $(textboxes).keypress(checkForEnter);
   } else {
      $(textboxes).keydown(checkForEnter);
   }

   function checkForEnter(event) {
      if (event.keyCode == 13) {
         currentTextboxNumber = textboxes.index(this);

         if (textboxes[currentTextboxNumber + 1] != null) {
           nextTextbox = textboxes[currentTextboxNumber + 1];
           nextTextbox.select();
      }

         event.preventDefault();
         return false;
      }
   }
});
