Dynamically loading inter-component JS/TS in an Angular application

Hey there! I have a current component structure set up like this:

appComponent
--infoComponent
    ---beforeComponent
    ---afterComponent

Both the before and after components have navbars with unique IDs, specifically navbar_before and navbar_after.

Here's my first question: Is it possible for me to use JS/TS code in the infoComponent to dynamically load either the before or after component based on a certain condition, without directly including

<app-before></app-before>
or
<app-after></app-after>
in the infoComponent? I want to assign this as a variable.

As for the second question: If the answer to the first question is yes, how can I access the navbar element with the ID of the before/after component from the infoComponent, similar to this example code:

var navbar = document.getElementById("navbar");

In summary, my goal is to create a sticky navbar with different menus as I scroll. Any helpful resources or guidance on how to achieve this would be greatly appreciated!

Answer №1

To incorporate both the before and after components into the parent component ("info component"), you can nest them within the parent component's HTML structure.

Utilize *ngIf in the child components to determine which component should be displayed. In the parent component's TypeScript file, declare a variable and access its value in the child components using @Input().
