Solution to the problem that the year cannot be displayed normally in Firefox_javascript skills

We will see this display on some websites when using Firefox:
The current time is: January 26, 108

The IE browser displays normally:
The current time is: January 26, 2008

The reason is the compatibility issue of javascript

var today = new date();var year = today.getYear();

In Firefox, getYear returns the value of "current year-1900", but Microsoft has made a change:
When the year of today is greater than or equal to 2000, 1900 is added directly and the returned 200X (instead of 10X)
For example: today’s year is 1999, return 99
Today’s year is 2000. Return 2000

A simple solution is to add a judgment:

year = (year<1900&#63;(1900+year):year);

There is also another method:
Call
through getFullYear getUTCFullYear

var year = today.getFullYear();
