Date.prototype.setYear() - JavaScript 编辑

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The setYear() method sets the year for a specified date according to local time. Because setYear() does not set full years ("year 2000 problem"), it is no longer used and has been replaced by the setFullYear() method.

Syntax

dateObj.setYear(yearValue)

Parameters

yearValue

An integer.

Return value

The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.

Description

If yearValue is a number between 0 and 99 (inclusive), then the year for dateObj is set to 1900 + yearValue. Otherwise, the year for dateObj is set to yearValue.

Examples

Using setYear()

The first two lines set the year to 1996. The third sets the year to 2000.

var theBigDay = new Date();

theBigDay.setYear(96);
theBigDay.setYear(1996);
theBigDay.setYear(2000);
