奇怪了，为什么“语句未结束”

  

   
   <
   SCRIPT LANGUAGE
   =
   "
   vbScript
   "
   >
    
HelpUrl
   =
   "
   http://www.baidu.com
   "
    
HelpTopic
   =
   "
   百度
   "
    
HelpData
   =
   "
    <a href=
   "
   &
   HelpUrl
   &
   "
    target=_blank>
   "
   &
   HelpTopic
   &
   "
    </a>
   "
    

   MsgBox
    HelpData 

   </
   SCRIPT
   >
    
以前一样的代码都不会，现在出错了。 
为什么？

  

 

VBS中&H是16进制的开头字符 
所以& H开头的变量，要在&后面加空格 
<SCRIPT LANGUAGE="vbScript"> 
HelpUrl = "http://www.baidu.com" 
HelpTopic = "百度" 
HelpData = " <a href=" & HelpUrl & " target=_blank>" & HelpTopic & " </a>" 
MsgBox HelpData 
</SCRIPT>
