Ext.tree.TreePanel 在IE下不正常加载

Ext.tree.TreePanel  在IE下不正常加载,两种解决方法 1 不停的加载，直到true 2 使用Ext.Ajax.request

 

代码

|< script language  = " javascript "  type = " text/javascript " >

 

                    //   var appmenu = new AppMenuView();

                     //  appmenu.render('context');

                      var  _url  =   ' http://localhost:14145/Menu/GetMenuFatherTree ' ;
                     //  _url="menu.ashx?model=0";

                      var  tree  =   new  Ext.tree.TreePanel({
                         id:  ' selectTree ' ,
                         plugins:  new  NodeMouseoverPlugin(),
                         height:  200 ,
                         autoScroll:  true ,
                         split:  true ,
                         loader:  new  Ext.tree.TreeLoader({ url: _url
                         , listeners: {
                              " loadexception " :  function (loader, node, response) {
                                 node.loaded  =   false ;
                                 node.reload.defer( 10 , node);  // 不停的加载，直到true
                             }
                         }
                     }),
                         root:
                          new  Ext.tree.AsyncTreeNode({
                           expanded:  true
                          }),
                         rootVisible:  false ,
                         requestMethod:  " GET "
                     });

                     tree.on( ' mouseover ' ,  function (node, e) {
                          if  ( ! node.isLeaf()) {
                             e.stopEvent();

                             tree.collapseAll();
                             node.expand();
                         }

                     });

                     tree.render( ' context ' );
                               
     < / script>
    
     |< script language  = " javascript "  type = " text/javascript " >
    
        Ext.BLANK_IMAGE_URL  =   ' ../js/ext/images/default/s.gif ' ;

       
             var  forumTree  =   new  Ext.tree.TreePanel({
                
                useArrows:  true ,
                enableDD:  true ,
                width:  200 ,
                height:  300 ,
                rootVisible:  false ,
                root:  new  Ext.tree.AsyncTreeNode({})
            });

            forumTree.render( ' Div1 ' );

           

             //  由于使用TreeLoader在IE下无法正常加载数据,所以使用Ajax先获取数据再填充数据到root node下 
            Ext.Ajax.request({
            url:  ' Menu/GetMenuFatherTree ' ,
                success:  function (request) {
                     var  data  =  Ext.util.JSON.decode(request.responseText);
                    forumTree.getRootNode().appendChild(data);
                    forumTree.getRootNode().expandChildNodes( true );

                    
                },
                failure:  function () {
                  

                    Ext.MessageBox.show({
                        title:  ' 版块管理 ' ,
                        msg:  ' 对不起,加载数据出现异常,请重试! ' ,
                        buttons: Ext.MessageBox.OK,
                        icon: Ext.MessageBox.ERROR
                    });
                }
            });
