Hi there,
a simple n00b question:
I have that Javascript snippet on my page (see below; taken from jquery,
actually).
I want to pass it the "@cities" array from the controller. But
what''s
the correct syntax, here?
See the 3rd line:
=======================================
<script>
$(document).ready(function(){
var data = @cities; <---- that''s not correct, is it?
$("#city").autocomplete(data);
});
</script>
=======================================
Thanks a lot for helping me!
Tom

So while Freddy''s solution will work, I would suggest putting your JavaScript in a separate file. In this case, there are two ways to get the value of @cities into the JavaScript code: 1. Use a .js.erb file and embed the value in ERb, just as you would in an inline script. This is very simple, but has the disadvantage that the browser cannot cache the script file, since the code is dynamically generated every time. 2 (my usual method). ---stylesheet--- .hidden: {display: none;} ---view--- <div id="cities" class="hidden"><%= @cities %></div> ---JavaScript--- $(document).ready(function(){ var data = $("#cities").innerHTML().doWhateverYouNeedToParseIt() $("#city").autocomplete(data); }); Good luck!
