Syntax
dateObj.setUTCHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])
参数

-
minutesValue
- 可选参数。表示分钟的整数,取值0到59之间。
-
secondsValue
-
可选参数。表示秒数的整数,取值0到59之间。如果指定了该参数,就要同时指定
minutesValue这个参数。
-
msValue
-
可选参数。表示毫秒的整数,取值0到999之间。如果指定了该参数,就要指定
minutesValue和secondsValue这两个参数。
返回值
返回从1970-01-01 00:00:00 UTC 到更新后的日期所表示时间的毫秒数。
描述
If you do not specify the minutesValue
, secondsValue
, and msValue
parameters, the values returned from the getUTCMilliseconds()
methods are used.
If a parameter you specify is outside of the expected range, setUTCHours()
attempts to update the date information in the Date
object accordingly. For example, if you use 100 for secondsValue
, the minutes will be incremented by 1 (minutesValue + 1
), and 40 will be used for seconds.
例子
使用 setUTCHours()
var theBigDay = new Date(); theBigDay.setUTCHours(8);
