Javascript日期方法不一致 - getDate vs getMonth [英] Javascript Date method inconsistency - getDate vs getMonth

问题描述

这导致我昨晚头痛，我想明白为什么Date对象中的getDate方法为1（返回值为1-31），而getMonth方法为0（返回0-11） 。我想知道为什么同一个对象的方法不一致。

我明白为什么很难改变现在的行为，但是有这样的理由是这样设计的这在第一位？

解决方案

我想几个月是0因为 Java做了同样的事情方式 JavaScript语言设计时。

编辑 Oracle取代了较旧的Java文档，有一个该页面的归档版本。

This caused me a bit of a headache last night and I wanted to understand why the getDate method in the Date object is 1 based (returns values from 1-31) while the getMonth method is 0 based (returns 0-11). I'm wondering why there is this inconsistency in methods for the same object.

I understand why it's difficult to change the behavior now but are there any reasons this was designed like this in the first place?

Documentation can be found here: http://www.w3schools.com/jsref/jsref_obj_date.asp

解决方案

I suppose months are 0-based because Java did it the same way when the JavaScript language was designed.

EDIT Oracle took down older Java documentation, there is an archived version of that page.
