纯JS脚本实现倒计时

1、.倒计时.time width:80px;height:25px;border:0px red solid;overflow:hidden;.time span float:left;line-height:25px;height:25px;overflow:hidden;.time span.danwei padding:0 1px;.clear height:0;clear:both;overflow:hidden; 距离世界杯开赛 var overa; overa = new Date(2014, 5, 12, 00, 00);/第数日时间当时间超过999小时 var localNow

2、= new Date(); function clock1() var local = new Date(); var intDiff = overa.getTime() - local.getTime(); if(intDiff = 0)document.getElementById(time1).innerHTML = 已经开赛啦！;/显示活动结束 return false; var day = Math.floor(intDiff / (1000 * 60 * 60) - (day * 24);var day1 = Math.floor(intDiff / (1000 * 60 * 60

3、 * 24);var hour = Math.floor(intDiff / (1000 * 60 * 60) - (day * 24); var hour2 = Math.floor(intDiff / (1000 * 60 * 60); var minute = Math.floor(intDiff / (1000 * 60) - (day * 24 * 60) - (hour * 60); var second = Math.floor(intDiff / 1000) - (day * 24 * 60 * 60); if (hour2 = 99) hour2 = 0 + hour2; i

4、f (day = 9) day = 0 + day; /*if (hour2 = 9) hour2 = 0 + hour2; if (minute = 9) minute = 0 + minute; if (second = 9) second = 0 + second; */document.getElementById(day_01).style.marginTop = (day1.toString().substr(0,1) * (-25) +px; document.getElementById(day_02).style.marginTop = (day1.toString().substr(1,1) * (-25) +px; document.getElementById(day_03).style.marginTop = (day1.toString(
