jsp页面根据当前时间和定义时间差计算动态倒计时http://www.jb51.net/article/74140.htm var maxtime =1000*60; //半个小时,按秒计算,自己调整! second=maxtime/1000; // 写一个方法,将秒数专为天数 var toDays = function(){ var s = second % 60; // 秒 var mi = (second - s) / 60 % 60; // 分钟
//时间差 function GetTime(time) {//di作为一个变量传进来 //如果时间格式是正确的,那下面这一步转化时间格式就可以不用了 var dateBegin = new Date(time.replace(/-/g, "/"));//将-转化为/,使用new Date var dateEnd = new Date();//获取当前时间 var dateDiff = dateEnd.getTime() - dateBegin.getTime();//时间差的毫秒数
public class Utill { public String TimeString(Date currentTime, Date beginTime){ /*默认为毫秒,除以1000是为了转换成秒*/ long interval=(currentTime.getTime()-beginTime.getTime())/1000;//秒 if(interval<0){ interval=-interval; } long temp=0; String result; if(interval<
SQL语句实例: select count(id) as num from public.user where cast((CURRENT_TIMESTAMP-login_timed) day as integer )<=1; 或 select count(id) as num from public.user where cast((CURRENT_TIMESTAMP-login_timed) hour as integer )<=24; 大家能够依据表结构稍作调整后使用
