Javascript date.setUTCMinutes()用法及代码示例

date.setUTCMinutes()是JavaScript中的内置函数，用于根据通用时间将分钟设置为使用Date()构造函数创建的日期对象。

用法:

DateObj.setUTCMinutes(Minutes_Value);

DateObj是使用Date()构造函数创建的有效Date对象，我们要在其中设置分钟。分钟的值是从0到59。

参数：这里的参数minutes_Value是我们要在使用Date()构造函数创建的日期中设置的分钟数。

返回值：它返回由setUTCMinutes()函数设置的新的即更新的分钟。

下面的程序演示了setUTCMinutes()函数：

<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>

输出：

52

错误和异常

• 示例1:如果在Date()构造函数中创建日期对象时我们没有给出任何分钟，则setUTCMinutes()函数仍然可以根据创建的Date对象中的通用时间设置新的分钟。

  <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>

  输出：

  51

• 示例2:如果在Date()构造函数中未提供任何参数，则setUTCMinutes()函数仍可以设置分钟，但月份，年份，日期等仍为当前值。

  <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>

  输出：

  42
  3
  1
  2018

  这里42是新分钟，3是当前月，即4月，1是当前日期，2018是当前年。

• 示例3:如果将分钟值66设置为setUTCMinutes()函数的参数，则会将6设置为分钟，因为分钟范围是从0到59，因此，此处减去60，因为0到59为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>

  输出：

  6
  6
