推荐答案

Y2K,只计算自 1900 年以来的年份.

It's a Y2K thing, only the years since 1900 are counted.

现在存在潜在的兼容性问题,getYear() 已被弃用,取而代之的是 getFullYear() - 来自 quirksmode:

There are potential compatibility issues now that getYear() has been deprecated in favour of getFullYear() - from quirksmode:

为了让事情变得更加复杂,date.getYear() 现在已被弃用,您应该使用 date.getFullYear(),而旧浏览器不支持它.但是,如果它有效,它应该总是给出全年,即.2000 而不是 100.

To make the matter even more complex, date.getYear() is deprecated nowadays and you should use date.getFullYear(), which, in turn, is not supported by the older browsers. If it works, however, it should always give the full year, ie. 2000 instead of 100.

您的浏览器使用这两种方法给出以下年份:

Your browser gives the following years with these two methods:

* The year according to getYear(): 108
* The year according to getFullYear(): 2008

Internet Explorer 和 Firefox 之间也存在实现差异,因为 IE 对 getYear() 的实现已更改为类似于 getFullYear() - 来自 IBM:

There are also implementation differences between Internet Explorer and Firefox, as IE's implementation of getYear() was changed to behave like getFullYear() - from IBM:

根据 ECMAScript 规范,getYear 返回年份减去 1900,原本打算返回98";1998 年.getYear 在 ECMAScript 版本 3 中被弃用,并替换为 getFullYear().

Per the ECMAScript specification, getYear returns the year minus 1900, originally meant to return "98" for 1998. getYear was deprecated in ECMAScript Version 3 and replaced with getFullYear().

Internet Explorer 将 getYear() 更改为与 getFullYear() 类似的工作方式并使其符合 Y2k 标准,而 Mozilla 保持标准行为.

Internet Explorer changed getYear() to work like getFullYear() and make it Y2k-compliant, while Mozilla kept the standard behavior.
