Angular - Pass an input value into a ngComponentOutlet created component?

To pass an input value into a component created with ngComponentOutlet in Angular, you can use a combination of @Input() properties and an intermediary data structure. Here's how to do it step-by-step:

Step-by-Step Guide

  1. Define the Component with Input Property: Create a component that accepts an input property.

Example Child Component

import { Component, Input } from '@angular/core'; @Component({ selector: 'app-child', template: `<p>Received Value: {{ value }}</p>`, }) export class ChildComponent { @Input() value: string; // Input property }
  1. Use ngComponentOutlet in the Parent Component: In your parent component, set up the ngComponentOutlet directive to dynamically load the child component.

Example Parent Component

import { Component } from '@angular/core'; import { ChildComponent } from './child.component'; @Component({ selector: 'app-parent', template: ` <input [(ngModel)]="inputValue" placeholder="Enter a value" /> <button (click)="loadComponent()">Load Component</button> <ng-container *ngComponentOutlet="dynamicComponent; injector: dynamicComponentInjector"></ng-container> `, }) export class ParentComponent { inputValue: string = ''; dynamicComponent = ChildComponent; // Reference to the child component dynamicComponentInjector: any; loadComponent() { this.dynamicComponentInjector = this.createInjector(this.inputValue); } createInjector(value: string) { const injector = Injector.create({ providers: [{ provide: 'inputValue', useValue: value }], parent: this.injector, // Use the parent injector }); return injector; } }
  1. Inject the Value in the Child Component: Use Inject to receive the input value in the child component.

Update the Child Component

import { Component, Inject, Input } from '@angular/core'; @Component({ selector: 'app-child', template: `<p>Received Value: {{ value }}</p>`, }) export class ChildComponent { value: string; constructor(@Inject('inputValue') value: string) { this.value = value; // Assign the injected value } }

Summary

  • Define Input Property: In the child component, use @Input() to define the input property.
  • Use ngComponentOutlet: In the parent component, use ngComponentOutlet to load the child component dynamically.
  • Create Injector: Use Injector.create to pass the input value to the child component.
  • Inject the Value: In the child component, use @Inject() to receive the value.

This setup allows you to pass an input value to a dynamically created component using ngComponentOutlet!
