如果联接条件与某些其他集合匹配,则要从集合中删除文档?例如
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule} from '@angular/router';
import {MatTabsModule} from '@angular/material/tabs';
import {TabsComponent} from "./tabs/tabs.component";
@NgModule({
imports: [
CommonModule,RouterModule,MatTabsModule]
declarations: [TabsComponent]
})
export class ComponentsModule { }
