JavaScript Date setUTCSeconds()用法及代碼示例

下麵是Date setUTCSeconds()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 second of 52 is being set in above Date 
   // Object with the help of setUTCSeconds() method 
   dateobj.setUTCSeconds(52); 
  
   // New second from above Date Object is 
   // being extracted using getUTCSeconds() 
   var B = dateobj.getUTCSeconds(); 
  
   // Printing new Second 
   document.write(B); 
</script>

輸出：
```
52
```

date.setUTCSeconds()方法用於根據通用時間將秒設置為使用Date()構造函數創建的日期對象。

用法:

DateObj.setUTCSeconds(seconds_Value);

參數：此方法接受上述和以下描述的單個參數：

seconds_Value:此參數保存我們要在使用Date()構造函數創建的日期中設置的秒數。

返回值：它返回由setUTCSeconds()方法設置的新的即更新的秒。

注意：DateObj是使用Date()構造函數創建的有效Date對象，我們要在其中設置秒數.second的值從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不給任何秒數，那麽setUTCSeconds()方法仍然可以設置新的秒數，該秒數將根據創建的Date對象中的通用時間作為其參數給出。

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

輸出：

程序2:如果在Date()構造函數中未提供任何參數，則setUTCSeconds()方法仍然可以設置第二個，但是月份，年份，日期等仍為當前設置。
根據通用時間，這裏42是新的第二秒，3是當前月份，即4月，1是當前日期，2018是當前年份。

<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 setUTCSeconds() method 
   dateobj.setUTCSeconds(42); 
  
   // Seconds from above Date Object is 
   // being extracted using getUTCSeconds() 
   var B = dateobj.getUTCSeconds(); 
  
   // 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 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：

程序3:如果將秒66的值作為setSeconds()方法的參數給出，則它將6設置為秒，因為第二範圍是從0到59的形式，因此，這裏減去60，因為0到59是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 second of 66 is being set in above Date 
   // Object with the help of setUTCSeconds() method 
   dateobj.setUTCSeconds(66); 
  
   // Seconds from above Date Object is 
   // being extracted using getUTCSeconds() 
   var B = dateobj.getUTCSeconds(); 
  
   // Minute from above Date Object is 
   // being extracted using getUTCMinutes() 
   var C = dateobj.getUTCMinutes(); 
  
   // Printing new seconds 
   document.write(B + "<br>"); 
  
   // Printing minutes 
   document.write(C); 
</script>

輸出：
