在运行时检查您是否具有正确的日期类型以进行比较

Question

OK so it's runtime. You are trying to compare Date's in JavaScript. Now sometimes in your code Dates are Strings, sometimes they are Dates and sometimes they are JQuery Objects wrapping around dates - what is returned from DatePicker.parseDate see: http://api.jqueryui.com/datepicker/

So before you just do:

date1 < date2 ...

You want to ensure both dates are in the correct format, JQuery date object ie what is returned from DatePicker.parseDate() .

What is your suggestion for doing this?

Answer 1

Solution is to do a truthy on the date variables

eg

myDate.getMonth()
