下麵是Date setSeconds()方法的示例。
- 例:
<script> // Here a date has been assigned // while creating Date object var dateobj = new Date('October 13, 1996 05:35:32'); // New second of 52 is being set in above Date // Object with the help of setSeconds() method dateobj.setSeconds(52); // New second from above Date Object is // being extracted using getSeconds() var B = dateobj.getSeconds(); // Printing new Second document.write(B); </script>
- 輸出:
52
date.setSeconds()方法用於將秒設置為使用Date()構造函數創建的Date對象。
用法:
DateObj.setSeconds(seconds_Value)
參數:此方法接受上述和以下描述的單個參數:
- seconds_Value:此參數保留用於在Date()構造函數中設置的秒值。
返回值:它返回具有更新的秒的新日期,該日期由setSeconds()方法設置。
注意:DateObj是使用Date()構造函數創建的有效Date對象,我們要在其中構造第二個對象。秒的值是從0到59。
上述方法的更多代碼如下:
程序1:如果在Date()構造函數中沒有給出任何第二個,則setSeconds()方法仍然設置了新的第二個作為其參數。
<script>
// Here second has not been assigned
// while creating Date object
var dateobj = new Date('October 13, 1996');
// New second of 51 is being set in above Date
// Object with the help of setSeconds() method
dateobj.setSeconds(51);
// New second from above Date Object is
// being extracted using getSeconds()
var B = dateobj.getSeconds();
// Printing new Second
document.write(B);
</script>
輸出:
51
範例2:如果在Date()構造函數中未提供任何參數作為參數,則仍將setSeconds()方法設置為第二,但是將月,年,日期等設置為當前方法。這裏42是新的秒,3是當前月,即4月,1是當前日期,2018是當前年。
<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 setSeconds() method
dateobj.setSeconds(42);
// Seconds from above Date Object is
// being extracted using getSeconds()
var B = dateobj.getSeconds();
// Month from above Date Object is
// being extracted using getMonth()
var C = dateobj.getMonth();
// Date from above Date Object is
// being extracted using getDate()
var D = dateobj.getDate();
// Year from above Date Object is
// being extracted using getFullYear()
var E = dateobj.getFullYear();
// 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>
輸出:
42 3 1 2018
範例3:如果將秒66的值作為setSeconds()函數的參數給出,則它將6設置為秒,因為秒的範圍是0到59和(66%60 = 6)。
此處6是新的秒,分鍾數從35變為36,因為第二範圍是0到59。因此當將66作為參數傳遞給setSeconds()函數時,它將在相應的Date對象中將秒設置為(66%60 = 6),並將相應的Date對象中的分鍾數增加(66/60 = 1)。
<script>
// Here date has been assigned
// while creating Date object
var dateobj =
new Date('October 13, 1996 05:35:32');
// New second of 66 is being set in above Date
// Object with the help of setSeconds() function
dateobj.setSeconds(66);
// Seconds from above Date Object is
// being extracted using getSeconds()
var B = dateobj.getSeconds();
// Minute from above Date Object is
// being extracted using getMinutes()
var C = dateobj.getMinutes();
// Printing new seconds
document.write(B + "<br />");
// Printing minutes
document.write(C);
</script>
輸出:
6 36
