I’m reading along with “Ajax on Rails” (2007) and the first exercise  
goes like this:

rails example  
cd example  
script/generate controller chap2 myaction  
script/server

Then editing example/app/views/myaction.html.erb to look like this:

## Hello World?

Firebug then says fone() is not defined. In the book the script is  
after the html but this does not matter.

What’s the deal? I have not tried src’ing an external script (as I am  
not sure where I would put that). I can’t really proceed if the js in  
the view is just going to be ignored. I also added the  
language=“javascript”, as this seems to be necessary sometimes in normal  
html pages, but this does not help.

1. the language attribute is not only not “necessary”, it’s deprecated;  
don’t use it.

2. spell text/javascript correctly and it should work as intended.
