废话不多说了，直接给大家贴代码了，具体代码如下所示：
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title></title>
<style type="text/css">
#result{
width:500px;
border:1px solid #CCCCCC;
background:#FFFFCC;
margin:50px auto;
font-size:24px;
color:#FF0000;
padding:20px;
}
</style>
<script type="text/javascript">
window.onload = function () {
showTime();
var start = document.getElementById("start");
start.onclick=function () {
var path = document.getElementById("path").value;
var time1 = document.getElementById("time1").value;
var time2 = document.getElementById("time2").value;
var time3 = document.getElementById("time3").value;
start.value = "等待打开抢单页面";
setInterval(function () {
var date = new Date();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
if (hour == time1 && minute == time2 && second == time3) {
window.open(path);
}
}, 100);
};
}
function showTime()
{
//创建Date对象
var today = new Date();
//分别取出年、月、日、时、分、秒
var year = today.getFullYear();
var month = today.getMonth()+1;
var day = today.getDate();
var hours = today.getHours();
var minutes = today.getMinutes();
var seconds = today.getSeconds();
//如果是单个数，则前面补0
month = month<10 ? "0"+month : month;
day = day <10 ? "0"+day : day;
hours = hours<10 ? "0"+hours : hours;
minutes = minutes<10 ? "0"+minutes : minutes;
seconds = seconds<10 ? "0"+seconds : seconds;
//构建要输出的字符串
var str = year+"年"+month+"月"+day+"日 "+hours+":"+minutes+":"+seconds;
//获取id=result的对象
var obj = document.getElementById("result");
//将str的内容写入到id=result的<div>中去
obj.innerHTML = str;
//延时器
window.setTimeout("showTime()",1000);
}
</script>
</head>
<body>
<div>
<h2>1,同步电脑时间和北京时间</h2>
<h2>2,设置path地址为需要抢券的地址和抢券时间</h2>
<!--<h3>抢券地址</h3><input type="text" id=path />-->
<h3>抢券地址(注意不要漏掉http://或者https://)</h3> <!--<textarea id="path" style="width:200px;height:80px;"></textarea>-->
<input type="url" id="path" style="width:auto"/>
<h3>抢券时间</h3>
<input type="text" id=time1 />时<input type="text" id=time2 />分
<input type="text" id=time3 />秒
<h2>3,点击等待，然后去点击抢券</h2>
<input type="button" id="start" value="开始"/><div id="result"></div>
</div>
</body>
</html>
