date.setMinutes()方法用於將分鍾設置為使用Date()構造函數創建的Date對象。
- 例:
<script> // Here a date has been assigned // while creating Date object var dateobj = new Date('October 13, 1996 05:35:32'); // New minute of 52 is being set in above Date // Object with the help of setMinutes() function dateobj.setMinutes(52); // New minute from above Date Object is // being extracted using getMinutes() var B = dateobj.getMinutes(); // Printing new minute document.write(B); </script>
- 輸出:
52
用法:
DateObj.setMinutes(Minutes_Value)
參數:此方法接受上述和以下描述的單個參數:
- minutes_Value:此參數保留用於在Date()構造函數中設置的分鍾值。
返回值:它返回具有更新分鍾的新日期,該日期由setMinutes()方法設置。
注意:DateObj是使用Date()構造函數創建的有效Date對象,我們要在其中設置分鍾。分鍾的值是從0到59。
上述方法的更多代碼如下:
程序1:如果在Date()構造函數中創建日期對象時我們沒有給出任何分鍾,則setMinutes()方法仍然設置新分鍾作為其參數。
<script>
// Here minute has not been assigned
// while creating Date object
var dateobj = new Date('October 13, 1996');
// new minute of 51 is being set in above Date
// Object with the help of setMinutes() method
dateobj.setMinutes(51);
// new minute from above Date Object is
// being extracted using getMinutes()
var B = dateobj.getMinutes();
// Printing new minute
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setMinutes()方法設置為分鍾,但月,年,日等變為當前方法。這裏42是新分鍾,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 minute of 42 is being set in above Date
// Object with the help of setMinutes() method
dateobj.setMinutes(42);
// Minutes from above Date Object is
// being extracted using getMinutes()
var B = dateobj.getMinutes();
// 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 minutes
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setMinutes()函數的參數中給定的分鍾值是66,則由於分鍾範圍是0到59和(66%60 = 6),所以它將6設置為分鍾。
這裏6是新的分鍾,而小時從05變為06,因為分鍾範圍是從0到59,即總計60,我們將新分鍾設置為66,這將小時從05增加1到06的分鍾變成6。
<script>
// Here date has been assigned
// while creating Date object
var dateobj =
new Date('October 13, 1996 05:35:32');
// new minute of 66 is being set in above Date
// Object with the help of setMinutes() function
dateobj.setMinutes(66);
// minute from above Date Object is
// being extracted using getMinutes()
var B = dateobj.getMinutes();
// Hour from above Date Object is
// being extracted using getHours()
var C = dateobj.getHours();
// Printing new minute
document.write(B + "<br />");
// Printing hour
document.write(C);
</script>
輸出:
6 6
