Good morning,

i am trying to write a js.erb.

<% if current_user.login == "admin" %>       var hide = false;     <% else %>       var hide = true;     <% end %>

or

<% escape_javascript(if current_user.login == "admin") %>       var hide = false;     <% escape_javascript(else) %>       var hide = true;     <% escape_javascript(end) %>

but every time I got an error in firebug: "invalid XML character".

Can't we just embended ruby in a javascript file?

Thank you
