Autocomplete the search in nav list by refresh with JQuery

Question

Currently I am working on a search box which works for a list on the navbar, I want the list could be refreshed while users enter the key words, in another word, there would be only the matched word showed in the list.

here is the code: http://jsfiddle.net/x69chen/sbAR6/

I cannot figure out how to reset the list to empty first, and then replace the list only the matched ones. I tried this

    $( "$nav-list123" ).empty();

But is does not work. Could anyone gives some hits? thanks

Answer 1

To reset the list:

$("#nav-list123").empty();

It works for me in the JS fiddle you show.
