Scene: A Select of form forms when you select different options, the form forms are entered differently, controlling the entry of form forms by hiding and displaying them. Submitting form forms before switching a select, validating against, switching Select, submitting form form, calling another validate () method does not work, and the returned value obtained is still the return value of the previous validation.
