Tips for efficiently handling input and output parameters in a dynamically generated component in Angular2 RC4

I need to pass several parameters to a component:

<sentence [sentence]="text.title" [selectedWord]="selectedWord" (selectionChanged)="selectionChanged($event)"></sentence>

To dynamically create a component, I am using the following code:

 addComponent() {
        this.compiler.resolveComponent(TaskHeaderComponent).then((factory) =>

        this.cmpRef = this.viewContainer.createComponent(factory, 0, this.viewContainer.injector));
    }

How can I pass these parameters to the created component:

  1. Input: [sentence]="text.title" [selectedWord]="selectedWord"
  2. Output Function: (selectionChanged)="selectionChanged($event)"

Thanks in advance!

Answer №1

While there isn't built-in support for dynamically added elements, you can achieve it through imperative means

You can set the sentence in this way: this.cmpRef.instance.sentence = ...
And also subscribe to selection changes like this: this.cmpRef.instance.selectionChange.subscribe(...)
