*       The problem is that there are two Choice drop-down boxes in the UI, 
the content of the second box is initially empty, and when the user selects 
an option in the first box, the corresponding option appears in the second 
box。*
*        For example, if the first box is month, the second box is day, and 
the user selects January, then the second box has 1... . 31, the user 
chooses February, the second frame is 1... 28。        *
*        My code is as follows.*
