set theDate to datePicker's dateValue()
#set theCal to current application's class "NSCalendar"'s currentCalendar()
-- unpack the components of theDate to a variable
set theComponents to theCal's components:254 fromDate:theDate
set theDate to current date
set day of theDate to 1 -- important
set seconds of theDate to theComponents's |second|()
set year of theDate to theComponents's |year|()
set month of theDate to theComponents's |month|()
set day of theDate to theComponents's |day|()
set hours of theDate to theComponents's hour()
set minutes of theDate to theComponents's minute()
return (theDate as text)
#return (theDate)
end datePicker
日期选择器不显示（至少在 Mojave 上）。但是，如果我在runModal 之前放置一个display alert，它确实会显示（但不是这样）。
我知道这可能与在以后的 Mac OSX 版本中需要 performSelectorOnMainThread 有关，但如果是这种情况，我无法添加它以使代码正常工作。有什么想法吗？
