setHours Method


function setHours(numHours : Number [, numMin : Number [, numSec : Number [, numMilli : Number ]]])

numHours: Required. A numeric value equal to the hour's value.

numMin: Optional. A numeric value equal to the minute's value.

numSec: Optional. A numeric value equal to the second's value.

numMilli: Optional. A numeric value equal to the milliseconds value.

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 numMinutes argument is optional, but not specified, JScript uses the value returned from the getMinutes method.

To set the hours value using Coordinated Universal 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.

В	Copy Code
function SetHoursDemo(nhr, nmin, nsec){ var d, s; //Declare variables. d = new Date(); //Create Date object. d.setHours(nhr, nmin, nsec); //Set hours, minutes, & seconds. s = "Current setting is " + d.toLocaleString() return(s); //Return new date setting. }

Copy Code

function SetHoursDemo(nhr, nmin, nsec){
   var d, s;                     //Declare variables.
   d = new Date();               //Create Date object.
   d.setHours(nhr, nmin, nsec);  //Set hours, minutes, & seconds.
   s = "Current setting is " + d.toLocaleString() 
   return(s);                    //Return new date setting.
}
