JavaScript Date setMinutes()用法及代碼示例


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

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:
