Coolite TreePanel 操作之一:TreePanel 刷新

脚本： 

function refreshTree(tree) {
            tree.el.mask('Loading...', 'x-loading-mask');

                    tree.root.ui.remove();
                    tree.initChildren(nodes);
                    tree.root.render();
                    tree.el.unmask();
                },
                failure: function(msg) {

                    tree.el.unmask();

                    Ext.Msg.alert('Failure', '未能加载数据');

                }

            });

脚本注册：

  string JsFunction = "refreshTree(#{TreePanelOrganization})";
                //string JsFunction = "alert('dd');";
                //string JsFunction = "refreshTree()";
                Coolite.Ext.Web.ScriptManager sm = Coolite.Ext.Web.ScriptManager.GetInstance(HttpContext.Current);
                sm.AddScript(string.Format("{0};", JsFunction));
