Scroll to top in Angular 2 after the page finishes loading

While fetching data, I have added a loading feature. My view list includes pagination and page size. The issue arises when I change the page size and move to other pages immediately after loading, as it does not scroll back to the top. I have tried adding

this.document.body.scrollTop = 0;
after loading, but it does not solve the problem.

Below is the code snippet for fetching data:

`getProducts() {
    this.productService
       .getProducts(this.args)
       .subscribe(
          data => {
              this.data = data;
              this.loadingService.hide();
              this.document.body.scrollTop = 0;
          },
          (error) =>
                console.log(error);
          }       
      );
    }`

Answer №1

To ensure that the page scrolls to the top when it is initialized in Angular, you can use the following code inside the ngOnInit lifecycle hook:

ngOnInit() {
    window.scrollTo(0,0);
}

Answer №2

Give this a go:

component.html

<button class="btn btn-primary" (click)="scrollToTop()">Scroll to Top</button>

component.ts

import { Component, Inject } from '@angular/core';
import { DOCUMENT } from '@angular/platform-browser';

export class Component {
    constructor(
        @Inject(DOCUMENT) private document: Document
    ) {}
    scrollToTop() {
        this.document.body.scrollTop = this.document.documentElement.scrollTop = 0;
    }
}

Answer №3

 import { Component, ViewChild } from '@angular/core';
    import { Content } from 'ionic-angular';

    @Component({...})
    export class MyPage{
      @ViewChild(Content) content: Content;

insert the following code snippet inside the subscribe function

this.content.scrollToTop();
