Hi, I need to pass in an array to JS function, which initializes its local variables. I have always called JS functions on events like onclick and such. How do i invoke JS function directly without such events?

You need to pass an array (in which language) to Javascript? Do you want to pass a Ruby array in? Or a Javascript array? Where do you want to invoke the Javascript from? Javascript is usually (as you say) event based. Julian. Learn Ruby on Rails!

I need to pass in Ruby array or hash to JS. I am trying to pass this array into JS (Google maps).

Use the .to_json method on the array or hash
ex.
["first", "second", "thrid"].to_json out puts
"[\"first\", \"second\",
\"third\"]"
in your view you do something like this
<script type=''text/javascript''>
var my_array = evalJSON(''<%= ["first",
"second", "third"].to_json
%>'');
//this will just alert the array;
Event.observe(window, ''load'',
alert(my_array.join('',''));
//this will alert first,second,third
</script>
