What are some strategies to avoid losing form data while switching between components without refreshing the page?

I am looking for a solution to seamlessly swap between two components, each containing a form, while retaining the data inputted by the user without submitting. This functionality is similar to switching tabs in simple HTML.

My approach involves using a variable called "value" in the parent component to determine which child component to display:

The parent component's HTML structure:


  <ul>
    <li class="nav-item"><a (click)="changeValue(1)">Dine In</a></li>
    <li class="nav-item"><a(click)="changeValue(2)">Delivery</a></li>
  </ul>
  </div>
  <app-dine *ngIf="value == 1"></app-dine>
  <app-delivery *ngIf="value == 2"></app-delivery>

In the parent component TypeScript file, I have implemented a simple function called changeValue:


changeValue(x){
    this.value=x;
}

The child components consist of forms where users can input data. The goal is to switch between components without losing any entered data:


<form>
  <input type="text"> //If the user writes anything here, I want to switch components without losing the data
</form>

If you have any suggestions or solutions, please share them. Thank you!

Answer №1

The solution involved utilizing the

[hidden]="value === x"

within component conditions rather than toggling it.
