Javascript時間操作小結

Javascript時間操作小結

 

 

js代碼

   1: /*擷取目前時間*/

   2: function getCurrentDate()

   3: {

   4:   var timeStr = '';

   5:   var curDate = new Date();

   6:   var curMonth = curDate.getMonth()+1;  //擷取當前月份(0-11,0代表1月)

   7:   var curDay = curDate.getDate();       //擷取當前日(1-31)

   8:   var curWeekDay = curDate.getDay();    //擷取當前星期X(0-6,0代表星期天)

   9:   var curHour = curDate.getHours();      //擷取當前小時數(0-23)

  10:   var curMinute = curDate.getMinutes();   // 擷取當前分鐘數(0-59)

  11:   var curSec =curDate.getSeconds();      //擷取當前秒數(0-59)

  12:   timeStr = curMonth+'月'+curDay+'日 周';

  13:   switch(curWeekDay)

  14:   {

  15:     case 0:timeStr += '日';break;

  16:     case 1:timeStr += '一';break;

  17:     case 2:timeStr += '二';break;

  18:     case 3:timeStr += '三';break;

  19:     case 4:timeStr += '四';break;

  20:     case 5:timeStr += '五';break;

  21:     case 6:timeStr += '六';break;

  22:   }

  23:   if(curHour < 10)

  24:   {

  25:     if(curMinute < 10)

  26:     {

  27:       if(curSec < 10)

  28:       {

  29:         timeStr += ' 0'+curHour+':0'+curMinute+':0'+curSec;

  30:       }

  31:       else

  32:       {

  33:         timeStr += ' 0'+curHour+':0'+curMinute+':'+curSec;

  34:       }

  35:     }

  36:     else

  37:     {

  38:       if(curSec < 10)

  39:       {

  40:         timeStr += ' 0'+curHour+':'+curMinute+':0'+curSec;

  41:       }

  42:       else

  43:       {

  44:         timeStr += ' 0'+curHour+':'+curMinute+':'+curSec;

  45:       }

  46:     }

  47:   }

  48:   else

  49:   {

  50:     if(curMinute < 10)

  51:     {

  52:       if(curSec < 10)

  53:       {

  54:         timeStr += ' '+curHour+':0'+curMinute+':0'+curSec;

  55:       }

  56:       else

  57:       {

  58:         timeStr += ' '+curHour+':0'+curMinute+':'+curSec;

  59:       }

  60:     }

  61:     else

  62:     {

  63:       if(curSec < 10)

  64:       {

  65:         timeStr += ' '+curHour+':'+curMinute+':0'+curSec;

  66:       }

  67:       else

  68:       {

  69:         timeStr += ' '+curHour+':'+curMinute+':'+curSec;

  70:       }

  71:     }

  72:   }

  73:   $(#time).text(timeStr);

  74: }

然後條用這個函數就行。

最後，對Javascript日期的部分函數做個小結：

var myDate = new Date();

myDate.getYear(); //擷取當前年份(2位)

myDate.getFullYear(); //擷取完整的年份(4位,1970-????)

myDate.getMonth(); //擷取當前月份(0-11,0代表1月)

myDate.getDate(); //擷取當前日(1-31)

myDate.getDay(); //擷取當前星期X(0-6,0代表星期天)

myDate.getTime(); //擷取目前時間(從1970.1.1開始的毫秒數)

myDate.getHours(); //擷取當前小時數(0-23)

myDate.getMinutes(); //擷取當前分鐘數(0-59)

myDate.getSeconds(); //擷取當前秒數(0-59)

myDate.getMilliseconds(); //擷取當前毫秒數(0-999)

myDate.toLocaleDateString(); //擷取當前日期

var mytime=myDate.toLocaleTimeString(); //擷取目前時間

myDate.toLocaleString( ); //擷取日期與時間
