Javascript获取当前时间函数和时间操作小结_javascript技巧

在项目需要一个计时器，效果如下：js代码：复制代码 代码如下: /*获取当前时间*/ function getCurrentDate() { var timeStr = ''; var curDate = new Date(); var curMonth = curDate.getMonth()+1; //获取当前月份(0-11,0代表1月) var curDay = curDate.getDate(); //获取当前日(1-31) var curWeekDay = curDate.getDay(); //获取当前星期X(0-6,0代表星期天) var curHour = curDate.getHours(); //获取当前小时数(0-23) var curMinute = curDate.getMinutes(); // 获取当前分钟数(0-59) var curSec =curDate.getSeconds(); //获取当前秒数(0-59) timeStr = curMonth+'月'+curDay+'日 周'; switch(curWeekDay) { case 0:timeStr += '日';break; case 1:timeStr += '一';break; case 2:timeStr += '二';break; case 3:timeStr += '三';break; case 4:timeStr += '四';break; case 5:timeStr += '五';break; case 6:timeStr += '六';break; } if(curHour { if(curMinute { if(curSec { timeStr += ' 0'+curHour+':0'+curMinute+':0'+curSec; } else { timeStr += ' 0'+curHour+':0'+curMinute+':'+curSec; } } else { if(curSec { timeStr += ' 0'+curHour+':'+curMinute+':0'+curSec; } else { timeStr += ' 0'+curHour+':'+curMinute+':'+curSec; } } } else { if(curMinute { if(curSec { timeStr += ' '+curHour+':0'+curMinute+':0'+curSec; } else { timeStr += ' '+curHour+':0'+curMinute+':'+curSec; } } else { if(curSec { timeStr += ' '+curHour+':'+curMinute+':0'+curSec; } else { timeStr += ' '+curHour+':'+curMinute+':'+curSec; } } } $("#time").text(timeStr); }然后条用这个函数就行。最后，对Javascript日期的部分函数做个小结：var myDate = new Date();myDate.getYear(); //获取当前年份(2位)myDate.getFullYear(); //获取完整的年份(4位,1970-????)myDate.getMonth(); //获取当前月份(0-11,0代表1月)myDate.getDate(); //获取当前日(1-31)myDate.getDay(); //获取当前星期X(0-6,0代表星期天)myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)myDate.getHours(); //获取当前小时数(0-23)myDate.getMinutes(); //获取当前分钟数(0-59)myDate.getSeconds(); //获取当前秒数(0-59)myDate.getMilliseconds(); //获取当前毫秒数(0-999)myDate.toLocaleDateString(); //获取当前日期var mytime=myDate.toLocaleTimeString(); //获取当前时间myDate.toLocaleString( ); //获取日期与时间
