I need a method to be called upon an ‘onblur’ event when a select list  
is no longer the focus - ideally, I would like it to work when the  
‘Enter’ key is hit. But, I am just trying to get the onblur to work,  
here is what I got:

\<%= select( “airlinemembership”, “membership”, Airline.find( :all,  
:order =\>  
‘name’ ).collect { |a| [a.name.downcase.capitalize, a.id]},  
{:update =\> ‘exclude\_1’}, {:onblur =\> ‘set\_exclude\_airline\_1’} ) %\>

Any ideas on how I can get the method ‘set\_exclude\_airline\_1’ to fire?  
Thanks,

-S

Hi,

I have tried to do this, but if you delve into the prototype  
javascript definitions I think the on blur is not actually implemented  
even though rails includes the option. I believe there is a way to  
detect the enter key in js, but I cant recall exactly how. What I  
ended up doing was to add a dummy field following the field I want to  
detect the blur. I then detect the on focus to do the call to remote,  
where I then do my update and use set focus to move to the next field.

Not ideal, but it achieves the desired result.
