以上是我的一个老系统的菜单代码，年前都是运行的好好的，这些天重新装了系统，然后当我在IE运行这个系统，并且点击 Accordion 的 HeaderTemplate时候，会出现126行找不到对象的JS脚本错误，很奇怪，但是我在火狐运行的时候，却是运行的好好的，搞了我一天了。请问高手，这究竟是什么问题？

  1.   

    webconfig的  <system.web>节加入:<httpHandlers>
          <remove verb="*" path="*.asmx"/>
          <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
          <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>
          <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler,System.Web.Extensions,Version=1.0.61025.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35" validate="false"/>
        </httpHandlers >

    上面一段有的，本来就是个ajax网站。。
    我刚才脚本调试了一下，发现问题在125行的红字部分，但是其他的机器以及不同的浏览器却是可以运行的，高手来解答啊。。....
    this._headersSize = this._getHeadersSize().height;var original = pane.content._original;switch (this._autoSize) {
    case AjaxControlToolkit.AutoSize.None :
    original.style.height = 'auto';original.style.maxHeight = '';break;case AjaxControlToolkit.AutoSize.Limit :
    var remaining = this._getRemainingHeight(false);original.style.height = 'auto';original.style.maxHeight = remaining + 'px';break;case AjaxControlToolkit.AutoSize.Fill :
    var remaining = this._getRemainingHeight(true);original.style.height = remaining + 'px';original.style.maxHeight = '';break;} 
    },
    _onHeaderClick : function(evt) {
    var header = evt.target;var accordion = this.get_element();while (header && (header.parentNode !== accordion)) {
    header = header.parentNode;}
    evt.stopPropagation();if (this._suppressHeaderPostbacks) {
    evt.preventDefault();}
    var index = header._index;if ((index === this._selectedIndex) && !this._requireOpenedPane) {
    index = -1;}
    .....
      

  3.   

    调试显示 header._index为null...

    确实有难题待解决
     先把这解决了,,你就是高人

  5.   

    会不会你的AjaxControlToolkit版本不一样?
      

  6.   

    现在可以大致确定的一点是，重新装了系统后，可能在ajax的版本之类的事情下出了某些事情，现在某些第三方控件，比如FCKeditor在本机上也是失效，但是在另外的机器上却是可以的。

    通过ghost恢复后，这个问题不再出现，结贴
