View page content above the keyboard in Ionic 2 by scrolling up

Attempting to create a login screen using Ionic where my fields are centered on the page. When I tap on an input field, I want the screen to scroll up to ensure that both the field and the login button remain in the center of the application screen.

I currently have what is described in 1, but I am aiming for 2.

I am unsure how to achieve this.

Below is my HTML code:

<ion-content class="login-page-background">
  <div class="content-login">
    <img src="assets/images/logo-yellow.svg" width="70%"><br><br>
    <div>
      <div class="login-information-bloc">
        <input placeholder="{{this.translate.get('...')}}" (select)="scrollUp()" class="input-login"/>
        <input type="password" placeholder="{{this.translate.get('...')}}" class="input-login"/><br>
        <p class="password-forgot">{{this.translate.get('...')}}</p>
      </div>
      <button (click)="login()" ion-button color="secondary">
        <label>{{this.translate.get('...')}}</label>
      </button>
    </div>

    <div class="flag-bloc">
      <p>{{this.translate.get('...')}}</p>
      <img src="assets/images/fr.svg" (click)="changeCountry('fr')" [ngClass]="{'flag-button' : this.fr_selected}" width="55px" style="margin: 0px 10px 0px 10px">
      <img src="assets/images/ch.svg" (click)="changeCountry('ch')" [ngClass]="{'flag-button' : this.ch_selected}" width="55px" style="margin: 0px 10px 0px 10px">
    </div>
  </div>
</ion-content>

Answer №1

Upon closer examination of the html structure, it becomes apparent that ion-content consists of fixed-content and scroll-content children. Therefore, when the keyboard is activated, scroll-content will automatically adjust its size to accommodate the new screen dimensions.

Given this information, I suggest avoiding setting fixed heights on your container classes. By doing so, your elements will be able to adapt to the resized container without any issues.

Answer №2

Dealing with a similar issue while working on the new Ionic 6 version, I was able to find a solution by utilizing the "keyboardDidShow" event to implement page scrolling.

  import { Keyboard } from "@capacitor/keyboard";
 import { Capacitor } from "@capacitor/core"; 

if (Capacitor.isNativePlatform()) {
  Keyboard.addListener("keyboardDidShow", () => {
    //scrollUp
   const elem = document.getElementById(elemId);
   const pageContent = document.getElementById(pageId);
    if (elem && pageContent) {
       pageContent.style.height = "400px";
       pageContent.style.overflowY = "scroll";
       elem.scrollTop += 5;  
    }
  });
}


let pageContent = document.getElementById(pageId);
if (pageContent) {
  // than resetScroll on the onChange event or focus
  pageContent.style.height = "100%";
  pageContent.style.overflow = "visible";
}

Hoping this workaround proves beneficial to others encountering a similar issue.
