下面是Date setUTCSeconds()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 GMT-3:00'); // New second of 52 is being set in above Date // Object with the help of setUTCSeconds() method dateobj.setUTCSeconds(52); // New second from above Date Object is // being extracted using getUTCSeconds() var B = dateobj.getUTCSeconds(); // Printing new Second document.write(B); </script>
- 输出:
52
date.setUTCSeconds()方法用于根据通用时间将秒设置为使用Date()构造函数创建的日期对象。
用法:
DateObj.setUTCSeconds(seconds_Value);
参数:此方法接受上述和以下描述的单个参数:
- seconds_Value:此参数保存我们要在使用Date()构造函数创建的日期中设置的秒数。
返回值:它返回由setUTCSeconds()方法设置的新的即更新的秒。
注意:DateObj是使用Date()构造函数创建的有效Date对象,我们要在其中设置秒数.second的值从0到59。
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给任何秒数,那么setUTCSeconds()方法仍然可以设置新的秒数,该秒数将根据创建的Date对象中的通用时间作为其参数给出。
<script>
// Here second has not been assigned according to
// universal time while creating Date object
var dateobj = new Date('October 13, 1996 GMT-3:00');
// New second of 51 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(51);
// New second from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Printing new Second
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setUTCSeconds()方法仍然可以设置第二个,但是月份,年份,日期等仍为当前设置。
根据通用时间,这里42是新的第二秒,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
// while creating Date object
var dateobj = new Date();
// New second of 42 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(42);
// Seconds from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Month from above Date Object is
// being extracted using getUTCMonth()
var C = dateobj.getUTCMonth();
// Date from above Date Object is
// being extracted using getUTCDate()
var D = dateobj.getUTCDate();
// Year from above Date Object is
// being extracted using getUTCFullYear()
var E = dateobj.getUTCFullYear();
// Printing new seconds
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:如果将秒66的值作为setSeconds()方法的参数给出,则它将6设置为秒,因为第二范围是从0到59的形式,因此,这里减去60,因为0到59是60。
<script>
// Here date has been assigned according to
// universal time while creating Date object
var dateobj =
new Date('October 13, 1996 05:35:32 GMT-3:00');
// New second of 66 is being set in above Date
// Object with the help of setUTCSeconds() method
dateobj.setUTCSeconds(66);
// Seconds from above Date Object is
// being extracted using getUTCSeconds()
var B = dateobj.getUTCSeconds();
// Minute from above Date Object is
// being extracted using getUTCMinutes()
var C = dateobj.getUTCMinutes();
// Printing new seconds
document.write(B + "<br>");
// Printing minutes
document.write(C);
</script>
输出:
6 36
