I am just learning Ruby.  
I created a simple application where an record is added from a “new”  
view. Some input fields are defined as a select option (using a  
helper). Now I want to add a Javascript function with “onclick”  
function. How can I do it?

Helper:

module MypagesHelper  
def my\_pictures  
pictures = [‘pic1’, ‘pic2’, ‘pic3’, ‘pic4’,‘pic5’,‘pic6’]  
pictures\_list = pictures.sort  
pictures\_list.collect{|l| l}  
end  
end

View:  
\<% form\_for(@mypage) do |f| %\>  
\<%= f.error\_messages %\>

```
<%= f.label :backgroud_picture %><br />

```

\<%= f.select :backgroud\_picture, my\_pictures %\>

Thanks,

Zalek
