Authentic property does not reveal its contents

Currently, I am utilizing Angular2 and my goal is to only display a component if a certain property is true. The issue arises when trying to show the <sci-company-form> element when the sci variable is set to true.

When setting public sci: boolean = true or public sci: boolean = false, everything works as expected. Even though this appears to be a simple scenario, I am struggling to find a solution that aligns with what I expect.

This is how it's implemented in the HTML file:

<input type="checkbox" (change)="isSci($event.target.checked)">
<sci-company-form *ngIf="sci"></sci-company-form>

And here is the TypeScript code snippet from the component:

public sci: boolean;

    isSci($event: boolean) {
        this.sci = $event;
        console.log("this.sci : " + this.sci + "$event :" + $event);
     }

Answer №1

One possible way to accomplish this is through the following code:

<input type="checkbox" [(ngModel)]="x"/>

<hello *ngIf="x"></hello>

Answer №2

Is the expected boolean value displayed when printing $event?

In my opinion, setting an initial value for the boolean property is essential to ensure proper functionality when using ngIf with that condition.

Answer №3

experiment with removing the target

<input type="checkbox" (change)="checkIfSci($event.checked)">
<sci-company-form *ngIf="isSci"></sci-company-form>
