  e2c();
  GetDateString();
  GetcDateString();
  strcnCanlender.innerText = DateString + "\n" + cDateString; //显示!
}
</script>
</head>
<body>
要保存一年的信息,其实只要两个信息就可以了:1.农历每个月的大小"#00ff00"/>
<input type="button" value="开始转换" onclick="cnCanlender()"/>
<div id="strcnCanlender" name="strcnCanlender">
</div>
</body>
</html>

运行效果图如下:
