When I select an option from the first SELECT field, the second SELECT field just grays out. Any ideas? Thanks. This isn’t working for me…

Do-over: I’ve heard that IE doesn’t like to replace the <option> contents of a <select>, so the thing to do here is to wrap the <select> in a span/div/whatever and replace the whole <select> each time.

I'm pretty sure Ruby methods automagically return the last thing that gets evaluated within. Oh, and I don’t think you even need the return statement.

If you’re in Rails, you can take advantage of the Inflector class and do something like this:

>> phrase = ‘my Dog hAs FlEas’
=> “my Dog hAs FlEas”
>> phrase.downcase.gsub(/\s/, ‘_’).camelize
=> “MyDogHasFleas”

And to add to it: one way to make this concept even shorter (albeit a bit more terse) is to use the options_from_collection_for_select in the "get_cities.rhtml" file. For the example above just replace the 3 lines with this one line: thanks again! Thanks for the walk through, saved me loads of time.
