I need to validate the date field using jQuery UI Date Picker

I plan on using a text field in conjunction with the Date Picker, but neeed to add some validation for when the user types in an invalid date. When they use the calendar control, it's pre-validated. But when they type it they may enter 6/31/2011, for example.

I was told this code finds an invalid date and reports that to the user. But it doees not work.

I assume when the date in the text field does not match what's in the date picker, it's an invalid date. True?


onClose: function (dateText, inst) {
  if (dateText != $.datepicker.formatDate($.datepicker.regional[''].dateFormat, Date.parse  (dateText)))
  {
      alert("The date you specified is not a valid date.");
      this.value = '';
  }
}

This does not report an invalid date and it also prevents the calendar rom opening on mouse click, when the field is not empty.

Can someoen please telll me what I am doing wrong?

Thanks.
