然后在ASP页面中有如下一段JS代码:
_________________________________________________________________________
function mOvr(f_type) {                                              
  var s = '<table width="60" height="20" border="0" cellpadding="0" cellspacing="0">';                                           
      s += '<td width="60" height="20" align="center" valign="top" background=""> ';                              
      s += '<table width="60" height="20" border="0" cellpadding="0" cellspacing="0" bordercolor="A3E93F" style="border: 1 solid #A3E93" bgcolor="#F3FEED">';                                      
      switch(f_type)
      {
      case "stype":s +=stype_list();
      break;
      case "grade":s +=grade_list();
      break;
      case "edition":s +=edition_list();  
      break;
      }
      s +='</table>';                                 
      s +=' </td>';                              
      s +='</tr>';                              
      s +='<tr>';                              
      s +='<td valign="top"><img src="" width="45" height="2"></td>';                               
      s +=' </tr>';                              
      s +='</table>';                              
                              
                              
   document.all["Layer1"].innerHTML = s;                                
   dStyle.visibility = "visible";                               
   dStyle.bgcolor="#F0FFD4";                              
                              
//   if (snow == 0) {                              
       dStyle.left = posx+offsetx-(width/2);                               
       dStyle.top = posy+offsety;                              
       dStyle.visibility = "visible";                              
       snow = 1;

  setTimeout( "DoHidden()", 6000);

浏览ASP页面的时候,出现"缺少对象",但是直接把最上面lm_menu.js文件中的代码直接放在ASP页面中就没有问题,问题出在什么地方呢?谢谢大家帮助!
