Javascript Error

I am using document.observe("dom:loaded", function() in global.js ,Its
giving error document.observe is not an

function.

Have you included the prototype javascript files in your layout?

You can add this line in element of your layout file (/app/views/layout/.html.erb)

<%= javascript_include_tag :defaults %>

Also global.js should be loaded after <%=
javascript_include_tag :defaults %> .
