<script>
function Inner(value)

      case "spe_ishot":
         document.all.GY.innerhtml = "<select name='key' style='width:100;border:1px solid;'>
                   <option value='1'>已推荐</option><option value='0'>推荐</option></script>"

                   <option value='1'>已排名</option><option value='0'>排名</option></script> "
             break;    
                        
      default      
         document.all.GY.innerhtml = " <input type='text' name='key' />"

</script>
运行时怎么页面上会有如下的显示：
" break; case "spe_istop": document.all.GY.innerhtml = " 已置顶置顶" break; case "spe_isorder": document.all.GY.innerhtml = " 已排名排名 " break; default document.all.GY.innerhtml = " " break; } }
这种函数怎么会有显示呢？ 请指点一下

不写调用时，只有这一段就有这种显示
 <select name="condition" style="width:150;border:1px solid;" onChange="Inner(options[selectedIndex].value)">    
     <option value="spe_comid" <%If(InStr(getcondition,"spe_comid") > 0)Then%>selected<%End If%>>企业名称</option>
     <option value="spe_ishot" <%If(InStr(getcondition,"spe_ishot") > 0)Then%>selected<%End If%>>推荐情况</option>
     <option value="spe_istop" <%If(InStr(getcondition,"spe_istop") > 0)Then%>selected<%End If%>>置顶情况</option>
     <option value="spe_isorder" <%If(InStr(getcondition,"spe_isorder") > 0)Then%>selected<%End If%>>排名情况</option>
     </select>
