Extjs4.x treepanel,treegrid 节点选择,选中某个节点
//官方推荐 this.getModuleGrid().getRootNode().cascadeBy(function () { this.set("checked", false); if (ids.indexOf(this.data["Id"].toString()) > -1) { this.set("checked", true); } }); //通过Children方式 GetChilds: function (idArray, node) { ts = this; childnodes = node.childNodes; Ext.each(childnodes, function () { var nd = this; idArray.push(nd.getId()); if (nd.hasChildNodes()) { ts.GetChilds(idArray, nd); } }); } //根据ID获取Node var node=treepanel.getNodeById(node_id); // treepanel.expandPath(node.getPath()) treepanel.getSelectionModel().select(node)
