我正在使用mongodb作为节点,我正在尝试根据一些设置过滤器聚合一组文档,然后将其限制为10.我将它聚合得很好并且限制很好但是我需要在之前获得聚合文档的总数我把它们限制在10.
这是我的代码.
var qry = [];
if (filter.FocusArea && filter.FocusArea != "(None)") {
qry.push({
$match: { 'ProgramAreaId': filter.FocusArea }
});
}
if (filter.Status && filter.Status != "(None)") {
qry.push({
$match: { 'StatusId': filter.Status }
});
}
if (filter.ProgOfficer && filter.ProgOfficer != "(None)") {
qry.push({
$match: { 'ProgramOfficerId': filter.ProgOfficer }
});
}
if (filter.Fund && filter.Fund != "(None)") {
qry.push({
$match: { 'FundId': filter.Fund }
});
}
var skipNbr = (parseInt(filter.Page) * 10 - 10);
qry.push({ $project: { _id: '$_id', count: …javascript mongodb node.js aggregation-framework mongodb-aggregation
我想重写 Router::navigate 并直接在 Router 类中执行一些代码（例如日志）
export const routes: Routes = [
{
path: '',
redirectTo: '/home',
pathMatch: 'full'
}
];
export function routerFactory(rootComponentType: Type<any> | null, urlSerializer: UrlSerializer,
rootContexts: ChildrenOutletContexts, location: Location,
injector: Injector, loader: NgModuleFactoryLoader,
compiler: Compiler, config: Router): Router {
return new MyRouter(
rootComponentType,
urlSerializer,
rootContexts,
location,
injector,
loader,
compiler,
config
);
}
@NgModule({
declarations: [
AppComponent,
...
],
imports: [
routing,
...
],
providers: [

{
provide: Router,
useFactory: routerFactory,
deps: [Type, UrlSerializer, ChildrenOutletContexts, Location, Injector, …我之前已经构建了一个AngularJS项目并且熟悉语法.这次我ng-controller="UniversalCtrl as universal"不能工作,我已经尝试了一切.如果我采取universal.showHeader == true并改变它是showHeader == true有效的,但我需要它作为变量universal.就像我说的,我有其他项目遵循相同的结构,他们工作正常.
