[Seaside] Getting the selected text in a textArea

[Avi Shefi]

How about this:

    html hiddenInput id: 'selectedText';
        callback: [ :value | aString := value ].
    html textArea name: 'myTextArea'.
    html break.
    html submitButton
        onClick: [ 'getFocusedTextArea(); submitForm(this)' ];
        with: 'Get the selected text magically'.

Change the getFocusedTextArea Javascript function so it assigns it value to
the hidden field 'selectedText'.
Don't forget to check what happens when there is no selected text (either
disable the form submission, or do validation on the callback).


Regards,
Avi.
