#update_page {|gs| ... } ⇒ Object
Renders javascript in an html file
Example:
<%= update_page do |page|
page.alert('this gets translated to js!')
page.show('my_hidden_div')
end
%>
This returns (assuming Prototype is your Js Framework):
<script type='text/javascript'>
alert('this gets translated to js!');
$('my_hidden_div').show();
</script>
