问题 For a while, I was simply storing the contents of my website in a s3 bucket and could access all pages via the full url just fine. I wanted to make my website more secure by adding an SSL so I created a CloudFront Distribution to point to my s3 bucket.

问题 How do I pass an ngFor variable to the ng-content template. Example, the containing-component: <ul> <li *ngFor="let item of itemsArray"> <ng-content></ng-content> </li> </ul> The nested content-component: <div> <span *ngIf="item.type_one"></span> <span *ngIf="item.type_two"></span> </div> Example, both: <containing-component> <content-component> </content-component> </containing-component> 回答1: You can not use ng-content as dynamic template.

问题 I have a small issue that I can't figure out how to do. I am just learning Angular / Typescript and I can't figure out how I could remove some DOM elements.

I just have to use them. What I want to achieve is something like this( jQuery version):

问题 I'm trying to implement a Material table in my angular application. Pagination and Filter are working fine, but i'm not able to sort my table. My reference to MatSort is undefined. I did import it in AppModule: import {MatTableModule} from '@angular/material/table'; import {MatTooltipModule} from '@angular/material/tooltip'; import {MatButtonModule, MatCheckboxModule,MatPaginatorModule,MatInputModule} from '@angular/material'; import {MatSortModule} from '@angular/material/sort'; ...

问题 I am using the MatTable component from Angular Material to make a dynamic data table. I need to get the current position of a row. I can easily get the row on which the user clicked but I am unable to know its current position in the list (which depends on sort/filtering/pagination). Any idea? 回答1: in your mat-cell you can get index like *ngFor as below <mat-cell *matCellDef="let element;let i = index;"> {{ i }} </mat-cell> Update from Angular 5 use also index as i <ng-container matColumnDef=
