Question

就是遇到一些功能(问题)无从下手，不知道怎么去做。担心自己做不好，有种沮丧感。怎么去解决我的问题呢!   //grid控制器        $scope.gridOption.onRegisterApi=function(gridApi){            $scope.gridApi=gridApi;            gridApi.pagination.on.paginationChanged($scope,function(newPage,pageSize){                console.log("分页:"+newPage+","+pageSize);            });            gridApi.selection.on.rowSelectionChanged($scope,function(row){                $scope.entity=row.entity;                console.log($scope.entity);            });        }
