RE: [Rails-spinoffs] Event.observe

[Gregory Hill]

Title: Event.observe

That calls your function at the time you attach the event, returns the result from the function (null in this case) into the Event.observe function, which is expecting a function reference.  So, it blows up.   You want something more like: Event.observe('mes_appearance_s0', 'change', function () { ShowItem($F('mes_appearance_s0'), 'other', 'mes_appearance_s1'); });   Greg     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith Davis Sent: Tuesday, June 27, 2006 3:22 PM To: rails-spinoffs@lists.rubyonrails.org Subject: RE: [Rails-spinoffs] Event.observe   Ok. Now the event is working, but here's my real problem. Here's the observe script:   Event.observe('mes_appearance_s0', 'change', ShowItem($F('mes_appearance_s0'), 'other', 'mes_appearance_s1'));       and the code for ShowItem:         function ShowItem($value, $match, $item){    if($value == $match) $($item).style.display = "inline";  else $($item).style.display = "none";    }       This results in a Type Mismatch error.
