Of course you can do the same with Scriptaculous:

html textInput
    onFocus: (html request
         callback: [ :value | current := value ]
         value: (SUEvent new element; access: 'id'));
    ...

Or more efficiently assign the same event to all input fields on the page:

html selector
    add: 'input';
    do: [ :each |
        each element
            on: 'blur' do: (html request
                callback: [ :value | current := value ]
                value: (SUEvent new element; access: 'id') ]

Cheers,
Lukas
