下面是Date setUTCMilliseconds()方法的示例。
- 例:
<script> // Here a date has been assigned according to // universal time while creating Date object var dateobj = new Date('October 13, 1996 05:35:32:77 GMT-3:00'); // New millisecond of 52 is being set in above Date // Object with the help of setUTCMilliseconds() method dateobj.setUTCMilliseconds(52); // New millisecond from above Date Object is // being extracted using getUTCMilliseconds() var B = dateobj.getUTCMilliseconds(); // Printing new millisecond document.write(B); </script>
- 输出:
52
date.setUTCMilliseconds()方法用于根据通用时间将毫秒设置为使用Date()构造函数创建的日期对象。
用法:
DateObj.setUTCMilliseconds(milliseconds_Value);
参数:该方法接受上述和以下描述的单个参数:
- milliseconds_Value:此参数保留用于在Date()构造函数中设置的毫秒值。
返回值:它返回由setUTCMilliseconds()方法设置的新的即更新的毫秒数。
注意:DateObj是使用Date()构造函数创建的有效Date对象,其中我们要根据通用时间设置毫秒。毫秒值是从0到999。
上述方法的更多代码如下:
程序1:如果在Date()构造函数中创建日期对象时不提供毫秒数,则setUTCMilliseconds()方法仍然可以设置新的毫秒数,该毫秒数作为其参数在创建的Date对象中给出。
<script>
// Here millisecond has not been assigned according
// to universal time while creating Date object
var dateobj = new Date('October 13, 1996 GMT-3:00');
// New millisecond of 51 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(51);
// New millisecond from above Date Object is
// being extracted using getUTCMilliseconds()
var B = dateobj.getUTCMilliseconds();
// Printing new millisecond
document.write(B);
</script>
输出:
51
程序2:如果在Date()构造函数中未提供任何参数,则setUTCMilliseconds()方法仍然可以设置毫秒,但是根据通用时间,月,年,日期等仍为当前时间。
根据通用时间,此处42是新毫秒,3是当前月份,即4月,1是当前日期,2018是当前年份。
<script>
// Here nothing has been assigned according
// to universal time while creating Date object
var dateobj = new Date();
// New millisecond of 42 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(42);
// Milliseconds from above Date Object is
// being extracted using getUTCMilliseconds()
var B = dateobj.getUTCMilliseconds();
// Month from above Date Object is
// being extracted using getUTCMonth()
var C = dateobj.getUTCMonth();
// Date from above Date Object is
// being extracted using getDate()
var D = dateobj.getUTCDate();
// Year from above Date Object is
// being extracted using getUTCFullYear()
var E = dateobj.getUTCFullYear();
// Printing new milliseconds
document.write(B + "<br />");
// Printing current month
document.write(C + "<br />");
// Printing current date
document.write(D + "<br />");
// Printing current year
document.write(E);
</script>
输出:
42 3 1 2018
程序3:如果将毫秒值1006设置为setUTCMilliseconds()方法的参数,则会将6设置为毫秒,因为毫秒范围是从0到999,因此,此处减去1000,因为0到999为1000。
<script>
// Here date has been assigned according to
// universal time while creating Date object
var dateobj =
new Date('October 13, 1996 05:35:32:45 GMT-3:00');
// New millisecond of 1006 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(1006);
// Milliseconds from above Date Object is
// being extracted using getUTCMilliseconds()
var B = dateobj.getUTCMilliseconds();
// Second from above Date Object is
// being extracted using getUTCSeconds()
var C = dateobj.getUTCSeconds();
// Printing new Milliseconds
document.write(B + "<br />");
// Printing second
document.write(C);
</script>
输出:
6 33
