js 将时间转换成秒 计算倒计时

<script>//将时间统计成秒形式var EndTime = new Array(); EndTime = "2010-04-14 23:59:59".split(/[-/s:]/); var EndTime =(new Date(EndTime[0],EndTime[1]-1,EndTime[2],0,0,0)).valueOf();alert("EndTime==="+EndTime);function GetRTime() { var NowTime = new Date(); if(NowTime.getTime()<EndTime){ var nMS = EndTime - NowTime.getTime();var nD = Math.floor(nMS / (1000 * 60 * 60 * 24));var nH = Math.floor(nMS / (1000 * 60 * 60)) % 24;var nM = Math.floor(nMS / (1000 * 60)) % 60;var nS = Math.floor(nMS / 1000) % 60;document.getElementById("RemainD").innerHTML = nD;document.getElementById("RemainH").innerHTML = nH;document.getElementById("RemainM").innerHTML = nM;document.getElementById("RemainS").innerHTML = nS; setTimeout("GetRTime()", 1000); }else{$("#dateend").show();$("#datebegin").hide();$("#dealover").show();$("#dealbuy").hide();} } </script><div id=dateend></div><div id=datebegin></div><div id=dealover></div><div id=dealbuy></div>
