这是我单击文本框后出现的日历代码。这是表中的关闭单元格。单击关闭时，将调用close（）函数，日历将消失。但这并没有发生。为什么？请帮助我...提前谢谢..

这与分号无关。这些大多是可选的，在本例中不需要。函数close()是保留的，不能由onclick调用。只需将close()重命名为类似closeCalendar()的名称，它应该可以正常工作。

close是一个javascript Keyword你应该使用close以外的另一个词作为你的函数名称 有关更多信息，请查看 JavaScript 保留字

这是一个演示，说明它如何更优雅地工作

<input type="text" id="cal" onclick="table(this)"/>
<div id="container">
    <div id="calender"></div>
</div>    

function nameofmonth(month)  {  
  return ["January","February","March","April","May","June","July","August","September","October","November","December"][month];
}  
function closeIt(){
  document.getElementById("container").style.display='none';
}
function table(cal) {
   var now=new Date(),
      hour=now.getHours(),
      minute=now.getMinutes(),
      second=now.getSeconds(),
      date=now.getDate(),
      month=now.getMonth(),
      year=now.getFullYear();
   now.setFullYear(year,month,1);
   var firstday=now.getDay(),
       monthname=nameofmonth(month);
   now.setFullYear(year,now.getMonth()+1,0); // last of this month
   var daysofmonth=now.getDate();
   var k=(firstday>0)?-(firstday-1):1;
   var table="<table border=5 cellspacing=3 cellpadding=8>"
   table +="<tr><th colspan=7>"+monthname + date+"th</th> <td  style='cursor:pointer' onclick='closeIt()'>[close]</td></tr>"
   table +="<tr><th>sun</th><th>mon</th><th>tue</><th>wed</th><th>thu</th><th>fri</><th>sat</th></tr>";
   for(var i=0;i<5;i++) {
     table+="<tr>";
     for (var j=0;j<7;j++) {
       if (k<=daysofmonth && k>0) {
         if (k==date) table+='<td id="clock" bgcolor="aqua">'+k+'</td>';
         else table+='<td style="cursor:pointer" onclick="document.getElementById('''+cal.id+''').value='''+(month+1)+'/'+k+'/'+year+'''">'+k+'</td>';
       }
       else table+="<td></td>";
       k++
     }
     table+="</tr>";
    }     
    document.getElementById("calender").innerHTML=table+"</table>";  
}
