Javascript date.setUTCMinutes()用法及代碼示例

date.setUTCMinutes()是JavaScript中的內置函數，用於根據通用時間將分鍾設置為使用Date()構造函數創建的日期對象。

用法:

DateObj.setUTCMinutes(Minutes_Value);

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。

參數：這裏的參數minutes_Value是我們要在使用Date()構造函數創建的日期中設置的分鍾數。

返回值：它返回由setUTCMinutes()函數設置的新的即更新的分鍾。

下麵的程序演示了setUTCMinutes()函數：

<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 minute of 52 is being set in above Date 
// Object with the help of setUTCMinutes() function 
dateobj.setUTCMinutes(52); 
  
// new minute from above Date Object is 
// being extracted using getUTCMinutes() 
var B = dateobj.getUTCMinutes(); 
  
// Printing new minute 
document.write(B); 
</script>

輸出：

52

錯誤和異常

• 示例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setUTCMinutes()函數仍然可以根據創建的Date對象中的通用時間設置新的分鍾。

  <script> 
  // Here minute has not been assigned according to 
  // universal time while creating Date object 
  var dateobj = new Date('October 13, 1996 GMT-3:00'); 
    
  // new minute of 51 is being set in above Date 
  // Object with the help of setUTCMinutes() function 
  dateobj.setUTCMinutes(51); 
    
  // new minute from above Date Object is 
  // being extracted using getUTCMinutes() 
  var B = dateobj.getUTCMinutes(); 
    
  // Printing new minute 
  document.write(B); 
  </script>

  輸出：

  51

• 示例2:如果在Date()構造函數中未提供任何參數，則setUTCMinutes()函數仍可以設置分鍾，但月份，年份，日期等仍為當前值。

  <script> 
  // Here nothing has been assigned according to 
  // universal time while creating Date object 
  var dateobj = new Date(); 
    
  // new minute of 42 is being set in above Date 
  // Object with the help of setUTCMinutes() function 
  dateobj.setUTCMinutes(42); 
    
  // Minutes from above Date Object is 
  // being extracted using getUTCMinutes() 
  var B = dateobj.getUTCMinutes(); 
    
  // 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 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

  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。

• 示例3:如果將分鍾值66設置為setUTCMinutes()函數的參數，則會將6設置為分鍾，因為分鍾範圍是從0到59，因此，此處減去60，因為0到59為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 minute of 66 is being set in above Date 
  // Object with the help of setUTCMinutes() function 
  dateobj.setUTCMinutes(66); 
    
  // minute from above Date Object is 
  // being extracted using getUTCMinutes() 
  var B = dateobj.getUTCMinutes(); 
    
  // Hour from above Date Object is 
  // being extracted using getUTCHours() 
  var C = dateobj.getUTCHours(); 
    
  // Printing new minute 
  document.write(B + "<br>"); 
    
  // Printing hour 
  document.write(C); 
  </script>

  輸出：

  6
  6
