The previous code creates two text fields and adds them to the display list. The first text field,
inputTxt, is an input text field that allows the user to enter Japanese text. The second text
field,
outputTxt, is a dynamic text field that displays error messages to the user, or echos the
Japanese string that the user types into the
inputTxt text field.
