实现代码:
$(document).ready(function(){
run(enddate);
});
//定时器
function run(enddate){
//如果enddate为后台传入的Date类型,这里直接转化为毫秒数
enddate=new Date(eddate.replace("T"," ").getTime());
//以500毫秒的速度执行(可以避免方法执行速度慢会影响展示效果的情况)0
var time = 500;
setInterval("dateDif('"+enddate+"')",time);
}
//计算时间相差
function dateDif(enddate){
var date = enddate - new Date().getTime();
var days = date / 1000 / 60 / 60 / 24;
var daysRound = Math.floor(days);
var hours = date/ 1000 / 60 / 60 - (24 * daysRound);
var hoursRound = Math.floor(hours);
var minutes = date / 1000 /60 - (24 * 60 * daysRound) - (60 * hoursRound);
var minutesRound = Math.floor(minutes);
var seconds = date/ 1000 - (24 * 60 * 60 * daysRound) - (60 * 60 * hoursRound) - (60 * minutesRound);
var secondsRound = Math.floor(seconds);
var time = "倒计时"+(daysRound+"天"+hoursRound +"时"+minutesRound+"分"+secondsRound+"秒");
$("#ytime").text(time);
}
