Object function Date() { [native code] } has no method 'compareTo' when use Date.js in Chrome

Question

I have these two date time variables in javascript:

first_date = Date.parse('05/21/2012 0:00:00 ');
second_date = Date.today();

If I'm using ( http://code.google.com/p/datejs/wiki/APIDocumentation#compareTo )

return first_date.compareTo(second_date)

then exception occurs:

Object function Date() { [native code] } has no method 'compareTo' in Google Chrome.

I'm using latest version of Date.js from http://www.datejs.com/

How to solve this issue ?

I will mention that other functions (add(-5).days(), today(), etc.) works fine.

PS: I took a look here ( http://code.google.com/p/datejs/issues/detail?id=129 ) but no workaround.

Answer 1

first_date and second_date are strings according to your code and Date.compare does not even exist unless you are using the svn-trunk version.

datejs defines Date.prototype.compareTo so you can only use date_obj_a.compareTo(...).

Answer 2

first_date = Date.parse('05/21/2012 0:00:00 ');
second_date = Date.today();

console.log(first_date.compareTo(second_date)); // just working fine
