Hello,

After reading and reading the documentation, I can’t append some  
javascript function into a select.

It’s not possible ?

## documentation:

select(object, method, choices, options = {}, html\_options = {})

## some code:

return select(:id, :year, [[‘2008’, 2008],  
[‘2007’, 2007],  
[‘2006’, 2006]], :selected =\> session[:user\_year], :onChange =\>  
‘enterprise\_function();’ )

## what I want:
2007 2006 2005

thanks, it works …

## so, reading in the docs:

select(object, method, choices, options = {}, html\_options = {})

you put the onChange… between curly braces {} in the options, and what  
can we put in the html\_options {}

thanks !

It’s the other way round. The first hash is options, which takes  
selected and a few other things. The second hash (html\_options) goes  
straight out to the rendered html, so if you put ‘foo’ =\> ‘bar’ then  
your select tag would have foo=“bar” as an attribute.
