The Infinite Scroll component calls an action to be performed when the user scrolls a specified distance from the bottom or top of the page.

The expression assigned to the ionInfinite event is called when the user reaches that defined distance. When this expression has finished any and all tasks, it should call the complete() method on the infinite scroll instance.

Infinite Scroll Content#

The ion-infinite-scroll component has the infinite scroll logic. It requires a child component in order to display content. Ionic uses its ion-infinite-scroll-content component by default. This component displays the infinite scroll and changes the look depending on the infinite scroll's state. It displays a spinner that looks best based on the platform the user is on. However, the default spinner can be changed and text can be added by setting properties on the ion-infinite-scroll-content component.

Custom Content#

Separating the ion-infinite-scroll and ion-infinite-scroll-content components allows developers to create their own content components, if desired. This content can contain anything, from an SVG element to elements with unique CSS animations.


<ion-content>  <ion-button (click)="toggleInfiniteScroll()" expand="block">    Toggle Infinite Scroll  </ion-button>
  <ion-infinite-scroll threshold="100px" (ionInfinite)="loadData($event)">    <ion-infinite-scroll-content      loadingSpinner="bubbles"      loadingText="Loading more data...">    </ion-infinite-scroll-content>  </ion-infinite-scroll></ion-content>
import { Component, ViewChild } from '@angular/core';import { IonInfiniteScroll } from '@ionic/angular';
@Component({  selector: 'infinite-scroll-example',  templateUrl: 'infinite-scroll-example.html',  styleUrls: ['./infinite-scroll-example.css']})export class InfiniteScrollExample {  @ViewChild(IonInfiniteScroll) infiniteScroll: IonInfiniteScroll;
  constructor() {}
  loadData(event) {    setTimeout(() => {      console.log('Done');;
      // App logic to determine if all data is loaded      // and disable the infinite scroll      if (data.length == 1000) { = true;      }    }, 500);  }
  toggleInfiniteScroll() {    this.infiniteScroll.disabled = !this.infiniteScroll.disabled;  }}



DescriptionIf true, the infinite scroll will be hidden and scroll event listeners
will be removed.

Set this to true to disable the infinite scroll from actively
trying to receive new data while scrolling. This is useful
when it is known that there is no more data that can be added, and
the infinite scroll is no longer needed.


DescriptionThe position of the infinite scroll element.
The value can be either top or bottom.
Type"bottom" ๏ฝœ "top"


DescriptionThe threshold distance from the bottom
of the content to call the infinite output event when scrolled.
The threshold value can be either a percent, or
in pixels. For example, use the value of 10% for the infinite
output event to get called when the user has scrolled 10%
from the bottom of the page. Use the value 100px when the
scroll is within 100 pixels from the bottom of the page.


ionInfiniteEmitted when the scroll reaches

the threshold distance. From within your infinite handler, you must call the infinite scroll's complete() method when your async operation has completed. |



DescriptionCall complete() within the ionInfinite output event handler when
your async operation has completed. For example, the loading
state is while the app is performing an asynchronous operation,
such as receiving more data from an AJAX request to add more items
to a data list. Once the data has been received and UI updated, you
then call this method to signify that the loading has completed.
This method will change the infinite scroll's state from loading
to enabled.
