What are the steps to display 10 items sequentially with the angular2-infinite-scroll package?

I'm currently working with the angular 2 infinite scroll module and I need to display 10 elements at a time. When the user scrolls down, the next 10 elements should be shown and the scrollbar should adjust accordingly. I've tried several methods but haven't had any luck so far. Any assistance would be greatly appreciated. Thank you.

Below is my code snippet:

`infinite-scroll
            [infiniteScrollDistance]="2"

            [infiniteScrollThrottle]="500"

            [scrollWindow]="false"
            (scrolled)="onScrollDown()"
            (scrolledUp)="onScrollUp()"

  style="overflow: auto; height:250px; width:350px" >
            <div class="scrollBar">
            <ul *ngFor="let item of list" >
             <li>{{item}}</li>
            </ul>
            </div>`

angular typescript infinite-scroll

Answer №1

Utilize the slice pipe to control the number of items displayed on the screen.

Create a variable to track the total number of items visible on the screen.

An example implementation would be:

<div>
  <h2 (click)="limit=limit+2">more</h2>
  <ul>
    <li *ngFor="let item of list | slice:0:limit">{{item}}</li>
  </ul>
  {{limit}}
</div>

If applicable, you could incorporate (scrolled) to increment the limit dynamically.

<div infinite-scroll
            [infiniteScrollDistance]="2"

            [infiniteScrollThrottle]="500"

            [scrollWindow]="false"
            (scrolled)="limit=limit+10"
            (scrolledUp)="onScrollUp()"

  style="overflow: auto;height:250px;width:350px" >
            <div class="scrollBar">
            <ul *ngFor="let item of list | slice:0:limit" >
             <li>{{item}}</li>
            </ul>
            </div>
