METHOD:
Date::setMinutes
object.setMinutes(minutesVal
[, secondsVal, msVal])
This method is used
to set the minutesfield for the supplied date according to local time. If you
do not supply the secondsVal and msVal
arguments, JavaScript will use the values returned using the getUTCSeconds
and getMilliseconds methods. Also, if the supplied argument is
outside the range expected, the setMinutes method will alter the
other parameters accordingly (see example below).
The available parameters are as follows:
minutesVal - an integer (0 thru 59) representing the minutes.
secondsVal - this value is an integer (0 thru 59) that represents
the seconds. If you supply this parameter you also must supply minutesVal.
msVal - this value is a number between 0 and 999
that represents milliseconds. If this value is supplied, you must also
supply minutesVal and secondsVal.
The following code uses the setMinutes method to change the value
of the myDate object and also demonstrates how this method will adjust
the other parameters if a value is supplied that exceeds the expected
range. In this case the secondsVal supplied is
100 which causes the minutesVal value to be incremented
by 1. This is calculated thus:
100 - 60 (maximum expected value for seconds) = 40 (this increments minuteVal
by one).
The result of this calculation (40) is then used for the secondsVal
parameter.
Code:
myDate = new Date()
document.write(myDate +"<br>")
myDate.setMinutes(15, 100)
document.write(myDate)
Output:
Fri Jul 9 13:47:32 UTC+0100 1999
Fri Jul 9 13:16:40 UTC+0100 1999 |
