将日期字符串转换为数字以进行比较

Question

I have dates in this format:

Jan. 4, 2011

I need to convert these dates to numbers then compare to make sure sort is correct (ascending or descending).

I've tried using Date.parse(s), but I keep getting NaN back as value. I believe it's the period after the 3 letter abbreviation thats screwing it up.

How do I convert these date string to number?

Answer 1

var myDate = "Jan. 4, 2011";
myDate = myDate.replace('.','');
var dateType = Date.parse(myDate);

dateType should give you a number
