如何在 Javascript/Jquery 中比较“EEE Mon dd hh:mm:ss TMZ yyyy”格式的两个日期字符串？

Question

I'm getting two Strings(dates) in EEE MMM dd hh:mm:ss TMZ yyyy format, I want to compare those two dates in Javascript/Jquery.

Example strings : Fri Aug 14 13:12:45 CDT 2020, Tue Aug 25 05:33:19 CDT 2020

You would need to parse the dates into a Javascript date object. With the format you're mentioning a simple new Date(longstringdateformat) would work. Then you can compare the value in milliseconds from the getTime() method.

function compareDates(){
     const date1 = new Date("Fri Aug 14 13:12:45 CDT 2020");
     const date2 = new Date("Tue Aug 25 05:33:19 CDT 2020");
     return date1.getTime()-date2.getTime();
}

here if the return value is negative date2 is greater than date1, if it's positive date2 is lesser than date1 and if it is 0 they are equal.
