JavaScript Date setUTCMilliseconds()用法及代碼示例

下麵是Date setUTCMilliseconds()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 05:35:32:77 GMT-3:00'); 
  
   // New millisecond of 52 is being set in above Date 
   // Object with the help of setUTCMilliseconds() method 
   dateobj.setUTCMilliseconds(52); 
  
   // New millisecond from above Date Object is 
   // being extracted using getUTCMilliseconds() 
   var B = dateobj.getUTCMilliseconds(); 
  
   // Printing new millisecond 
   document.write(B); 
</script>

輸出：
```
52
```

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

用法:

DateObj.setUTCMilliseconds(milliseconds_Value);

參數：該方法接受上述和以下描述的單個參數：

milliseconds_Value:此參數保留用於在Date()構造函數中設置的毫秒值。

返回值：它返回由setUTCMilliseconds()方法設置的新的即更新的毫秒數。

注意：DateObj是使用Date()構造函數創建的有效Date對象，其中我們要根據通用時間設置毫秒。毫秒值是從0到999。

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提供毫秒數，則setUTCMilliseconds()方法仍然可以設置新的毫秒數，該毫秒數作為其參數在創建的Date對象中給出。

<script> 
   // Here millisecond has not been assigned according  
   // to universal time while creating Date object 
   var dateobj = new Date('October 13, 1996 GMT-3:00'); 
  
   // New millisecond of 51 is being set in above Date 
   // Object with the help of setUTCMilliseconds() method 
   dateobj.setUTCMilliseconds(51); 
  
   // New millisecond from above Date Object is 
   // being extracted using getUTCMilliseconds() 
   var B = dateobj.getUTCMilliseconds(); 
  
   // Printing new millisecond 
   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setUTCMilliseconds()方法仍然可以設置毫秒，但是根據通用時間，月，年，日期等仍為當前時間。
根據通用時間，此處42是新毫秒，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 according  
   // to universal time while creating Date object 
   var dateobj = new Date(); 
  
   // New millisecond of 42 is being set in above Date 
   // Object with the help of setUTCMilliseconds() method 
   dateobj.setUTCMilliseconds(42); 
  
   // Milliseconds from above Date Object is 
   // being extracted using getUTCMilliseconds() 
   var B = dateobj.getUTCMilliseconds(); 
  
   // Month from above Date Object is 
   // being extracted using getUTCMonth() 
   var C = dateobj.getUTCMonth(); 
  
   // Date from above Date Object is 
   // being extracted using getDate() 
   var D = dateobj.getUTCDate(); 
  
   // Year from above Date Object is 
   // being extracted using getUTCFullYear() 
   var E = dateobj.getUTCFullYear(); 
  
   // Printing new milliseconds 
   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:如果將毫秒值1006設置為setUTCMilliseconds()方法的參數，則會將6設置為毫秒，因為毫秒範圍是從0到999，因此，此處減去1000，因為0到999為1000。

<script> 
   // Here date has been assigned according to 
   // universal time while creating Date object 
   var dateobj =  
   new Date('October 13, 1996 05:35:32:45 GMT-3:00'); 
  
   // New millisecond of 1006 is being set in above Date 
   // Object with the help of setUTCMilliseconds() method 
   dateobj.setUTCMilliseconds(1006); 
  
   // Milliseconds from above Date Object is 
   // being extracted using getUTCMilliseconds() 
   var B = dateobj.getUTCMilliseconds(); 
  
   // Second from above Date Object is 
   // being extracted using getUTCSeconds() 
   var C = dateobj.getUTCSeconds(); 
  
   // Printing new Milliseconds 
   document.write(B + "<br />"); 
  
   // Printing second 
   document.write(C); 
</script>

輸出：
