本文实例总结了jQuery实现的倒计时效果。分享给大家供大家参考,具体如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>Jquery实现倒计时效果</title><script language="javascript" src="jquery-1.3.2.min.js"></script><script type="text/javascript"> var SysSecond; var InterValObj; $(document).ready(function() { SysSecond = parseInt($("#remainSeconds").html()); //这里我是在服务端算好了剩余的秒数,并保存到客户端,如果过期则返回0 InterValObj = window.setInterval(SetRemainTime, 1000); //间隔函数,1秒执行 }); //代理,接单的时间+1小时减去当前时间的秒数 function SetRemainTime() { if (SysSecond > 0) { //alert(SysSecond); SysSecond = SysSecond - 1; var second = Math.floor(SysSecond % 60); // 计算秒 var minite = Math.floor((SysSecond / 60) % 60); //计算分 var hour = Math.floor((SysSecond / 3600) % 24); //计算小时 var day = Math.floor((SysSecond / 3600) / 24); //计算天 $("#remainTime").html(day + "天" + hour + "小时" + minite + "分" + second + "秒"); } else {//剩余时间小于或等于0的时候,就停止间隔函数 window.clearInterval(InterValObj); } }</script></head><body><div id="remainSeconds" style="display:none">18000</div><div id="remainTime" style="font-size:20px;font-weight:800;color:#FF9900"></div></body></html>
当我们在webservice里读取到数据库中的时间字段后,把时间分割判断。Javascript代码如下:
<script type="text/javascript" src="jquery.js"></script><script type="text/javascript">function Times() {var tempTime=document.getElementById("currTime").innerHTML.split(":");var hour=tempTime[0];var minute=tempTime[1];var second=tempTime[2];if(second>=1){second=(second-1>9)?(second-1):"0"+(second-1);}else{ second="59"; if(minute>=1){ minute=(minute-1>9)?(minute-1):"0"+(minute-1); }else{ minute="59"; if(hour>=1){ hour=(hour-1>9)?(hour-1):"0"+(hour-1); }else{ minute="00"; hour="0"+0; } }}document.getElementById("currTime").innerHTML=hour+":"+minute+":"+second;if(hour==0&&minute==0&&second==0){document .getElementById ("currTime").style .display ="none";}elsesetTimeout (Times,1000);}//当窗体加载是调用。相当于onload()事件 (function gettime() { $.ajax({ contentType:"application/json", type: "POST", url: "WebService.asmx/Gettime", data: "{'id':'1'}", dataType: 'json', success: function(msq){ document .getElementById ("currTime").innerHTML =msq.d ; } }); setTimeout (Times,1000) ; })(); </script>
多个倒计时>>>
