PHPCMS里的日历插件及在IE下报Calendar未定义

日历代码：

<link rel="stylesheet" type="text/css" href="calendar/jscal2.css"/>
<link rel="stylesheet" type="text/css" href="calendar/border-radius.css"/>
<link rel="stylesheet" type="text/css" href="calendar/win2k.css"/>
<script type="text/javascript" src="calendar/calendar.js"></script>
<script type="text/javascript" src="calendar/lang/en.js"></script>
    <tr>
        <th>上线时间 :</th>
        <td><input type="text" name="subject[fromdate]" id="fromdate" value="" size="10" class="date" readonly>&nbsp;<script type="text/javascript">
            Calendar.setup({
            weekNumbers: true,
            inputField : "fromdate",
            trigger    : "fromdate",
            dateFormat: "%Y-%m-%d",
            showTime: false,
            minuteStep: 1,
            onSelect   : function() {this.hide();}
            });
        </script></td>
    </tr>
    <tr>
        <th>下线时间 :</th>
        <td><input type="text" name="subject[todate]" id="todate" value="" size="10" class="date" readonly>&nbsp;<script type="text/javascript">
            Calendar.setup({
            weekNumbers: true,
            inputField : "todate",
            trigger    : "todate",
            dateFormat: "%Y-%m-%d",
            showTime: false,
            minuteStep: 1,
            onSelect   : function() {this.hide();}
            });
        </script></td>
    </tr>
    

在IE下报Calendar未定义：

调用时在IE下报  “Calendar”未定义  的错误，致使日期控件无法使用
 
     原因是由在IE下，calendar.js文件加载没有阻塞Calendar.setup（）方法的运行，Calendar.setup()在calendar.js未加载的情况，就开始执行了，所以就报出“Calendar”未定义  的错误
 
解决办法：
找到phpcmsbs/class/form.class.php文件
在174到182行

Calendar.setup({
weekNumbers: ‘.$showweek.‘,
   inputField : "‘.$id.‘",
   trigger    : "‘.$id.‘",
   dateFormat: "‘.$format.‘",
   showTime: ‘.$showsTime.‘,
   minuteStep: 1,
   onSelect   : function() {this.hide();}
});

改成：
$(function(){
Calendar.setup({
weekNumbers: ‘.$showweek.‘,
   inputField : "‘.$id.‘",
   trigger    : "‘.$id.‘",
   dateFormat: "‘.$format.‘",
   showTime: ‘.$showsTime.‘,
   minuteStep: 1,
   onSelect   : function() {this.hide();}
});
});
