Keep focus on an input box on an HTML form

gistfile1.js

/*
  The following is the only way I could find to solve an annoying problem
  I was having on an HTML Form. I needed to add items from an input box to a 
  multiple select control. I wanted to use the change event instead of a button
  to speed up the process. Everytime the entry was loaded into the select, the 
  select control received focus requiring the user to tab or click back into the 
  input box. I tried to use the focus event in multiple combinations and the
  following finally worked. 

  #new_item is an input that adds new items to a multiple select box

*/
var focusing = false

$('#new_item').blur(function(e){
	if(focusing){
		setTimeout(function(){
			$('#new_item').focus();
		}, 5);
		focusing = false;
	}
});

$('#new_item').on('change',function(e){
	$('#select').append($("<option></option>").attr("value", $('#new_item').val()).text($('#new_item').val()));

	$('#new_item').val('');
	focusingNewRegion = true;
});
