需要在body中添加—个表格，并在加载事件中调用“calendar”方法，代码如下所示：
</head>
<body onload=" Calendar()">
<table border="0" cellpadding="0" cellspacing="1" 
class="Calendar" id="caltable">
<thead>
     <tr align="center" valign="middle"> 
  <td colspan="7" class="Title">
   <a href="javaScript:subMonth();" title="上一月" 
Class="DayButton">3</a> 
   <input name="year" type="text" size="4" maxlength="4" 
onkeydown="if (event.keyCode==13){setDate()}" 
onkeyup="this.value=this.value.replace(/[^0-9]/g,'')"  
onpaste="this.value=this.value.replace(/[^0-9]/g,'')"> 年 
<input name="month" type="text" size="1" maxlength="2" 
onkeydown="if (event.keyCode==13){setDate()}" 
onkeyup="this.value=this.value.replace(/[^0-9]/g,'')"  
onpaste="this.value=this.value.replace(/[^0-9]/g,'')"> 月 
<a href="JavaScript:addMonth();" title="下一月" 
Class="DayButton">4</a>
  </td>
 </tr>
 <tr align="center" valign="middle"> 
  <script language="javascript">  
   document.write("<td class=DaySunTitle id=diary >" + days[0] + "</td>"); 
   for (var intLoop = 1; intLoop < days.length-1;intLoop++) 
    document.write("<td class=DayTitle id=diary>" + days[intLoop] + "</td>"); 
    document.write("<td class=DaySatTitle id=diary>" + days[intLoop] + "</td>"); 
  </script>
 </tr> 
</thead>
<tbody border="1" cellspacing="0" cellpadding="0" 
ID="calendar" ALIGN="CENTER" >
 <script language="javascript">
  for (var intWeeks = 0; intWeeks < 6; intWeeks++)
  {
   document.write("<TR style='cursor:hand'>");
   for (var intDays = 0; intDays < days.length;intDays++) 
document.write("<TD class=CalendarTD onMouseover='buttonOver();' 
onMouseOut='buttonOut();'></TD>");
   document.write("</TR>");
  } 
 </script>

</table>
</body>
