下面是Date setSeconds()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 month of January is being set in above Date // Object with the help of setUTCMonth() method dateobj.setUTCMonth(0); // New month from above Date Object is // being extracted using getUTCMonth() var B = dateobj.getMonth(); // Printing new month document.write(B); </script>
- 输出:
0
date.setUTCMonth()方法用于根据通用时间将月份设置为使用date()构造函数创建的日期对象。句法:
dateObj.setUTCMonth(month_Value);
参数:该方法接受上述和以下描述的单个参数:
- month_Value此参数保存用于在date()构造函数中设置的month的值。
返回值:它返回由setUTCMonth()方法设置的新的即更新的月份。
注意:dateObj是使用Date()构造函数创建的有效Date对象,我们要在其中构造月份。
上述方法的更多代码如下:
程序1:如果在Date()构造函数中没有给出任何月份,则setUTCMonth()方法仍然设置新的月份作为其参数。
<script>
// Here month has not been assigned according to
// universal time while creating Date object
var dateobj = new Date('1996, 05:35:32 GMT-3:00');
// New month of 2 is being set in above Date
// Object with the help of setUTCMonth() method
dateobj.setUTCMonth(2);
// New month from above Date Object is
// being extracted using getUTCMonth()
var B = dateobj.getUTCMonth();
// Printing new month
document.write(B);
</script>
输出:
2
程序2:如果在Date()构造函数中未提供任何参数作为参数,则仍将setUTCMonth()方法设置为月,但年,日期等根据通用时间变为当前的。
根据通用时间,此处11是12月的新月,1是当前日期,而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 month of 11 is being set in above Date
// Object with the help of setUTCMonth() method
dateobj.setUTCMonth(11);
// Month from above Date Object is
// being extracted using getUTCMonth()
var B = dateobj.getUTCMonth();
// Date from above Date Object is
// being extracted using getUTCDate()
var C = dateobj.getUTCDate();
// Year from above Date Object is
// being extracted using getUTCFullYear()
var D = dateobj.getUTCFullYear();
// Printing new month
document.write(B + '<br />');
// Printing current date
document.write(C + '<br />');
// Printing current year
document.write(D + '<br />');
</script>
输出:
11 1 2018
程序3:如果将setUTCMonth()方法的参数指定为month 15,则将3设置为month,因为month范围是0到11,因此,这里减去12是因为0到11为12。
这里3是4月的新月,因为月份范围是0到11,即总计12,所以年份从1996年变为1997,我们将新月份设置为3,从1996年起将年份增加1到1997,月份变成3到世界时间。
<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 month of 15 is being set in above Date
// Object with the help of setUTCMonth() method
dateobj.setUTCMonth(15);
// Month from above Date Object is
// being extracted using getUTCMonth()
var B = dateobj.getUTCMonth();
// Year from above Date Object is
// being extracted using getUTCFullYear()
var C = dateobj.getUTCFullYear();
// Printing new month
document.write(B + '<br />');
// Printing new year
document.write(C);
</script>
输出:
3 1997
