Applies to: Date Object
The setHours method is use to set the hour value in the Date object using local time. It return in milliseconds. To convert the millisecond to string use obj.toLocaleString( ).
Syntax
objDate.setHours(numHours[, numMin[, numSec[, numMilli]]])
The setHours method syntax has these parts:
Part |
Description |
numHours |
Required. A numeric value equal to the hours value. |
numMin |
Optional. A numeric value equal to the minutes value. Must be supplied if either of the following arguments are used. |
numSec |
Optional. A numeric value equal to the seconds value. Must be supplied if the following argument is used. |
numMilli |
Optional. A numeric value equal to the milliseconds value. |
Example
All set methods taking optional arguments use the value returned from corresponding get methods, if you do not specify an optional argument. For example, if the numMonth argument is optional, but not specified, JavaScript uses the value returned from the getMonth method.
To set the hours value using Universal Coordinated Time (UTC), use the setUTCHours method.
If the value of an argument is greater than its range or is a negative number, other stored values are modified accordingly. For example, if the stored date is "Jan 5, 1996 00:00:00", and setHours(30) is called, the date is changed to "Jan 6, 1996 06:00:00." Negative numbers have a similar behavior.
The following example illustrates the use of the setHours method:
function SetHours(nhr, nmin, nsec)
{
var d, s;
var sep = ":";
d = new Date();
d.setHours(nhr, nmin, nsec);
s = "Current setting is " + d.toLocaleString()
return(s);
}
document.write(SetHours(5, 26, 50));
