如何在ui-grid中获取所选节点的树级别

Question

在选择节点时，我想获得它的树级别和父级名称

gridApi.selection.on.rowSelectionChanged($scope,function(row){
        var msg = 'row selected ' + row.isSelected;
        $log.log(msg+"hello"+" "+row.entity.node);
        console.log( row.entity.$$hashKey);
        selectedRow =row.entity.node;
        $scope.favName = row.entity.nodeRelPath ;
    });
