ruby on rails - How do I run autocomplete directly from the server instead of the default JQuery UI autocomplete? -

i using jquery ui bundle fill in autocomplete search parameters in input html box.

html file:

<script src="js/jquery-1.9.1.js"></script> <script src="js/jquery-ui-1.10.3.custom.js"></script> <script> $(function() {    var userfirstnametags = [ "john",  "katy",  "will",  "shrek", ];    var userlastnametags = [ "snow",  "perry",  "smith",  "rooney", ];    $( "#user_first_name" ).autocomplete({    source: userfirstnametags    });   }); </script> 

---

the issue right username , other sensitive data have appears on html/js file on front end code.

i protect information + not want code load user data every time loads search page.

is there alternate way use autocomplete/ index autocomplete directly server-side? using ruby on rails server side.

jquery auto-completer gives option load data server. checkout link http://jqueryui.com/autocomplete/#remote
