Obtaining the TemplateRef from any HTML Element in Angular 2

Question

Obtaining the TemplateRef from any HTML Element in Angular 2

I am in need of dynamically loading a component into an HTML element that could be located anywhere inside the app component.

My approach involves utilizing the TemplateRef as a parameter for the

ViewContainerRef.createEmbeddedView(templateRef)

method to load the desired component dynamically.

For instance, I'm aiming for a code structure similar to this:

var myViewRef = this.viewContainer.createEmbeddedView(
  getTemplateRefFromNode(document.querySelector('.anySelector'))
);
this.resolver.resolveComponent(myComponent)
  .then(factory => {
    var newComponent = myViewRef.createComponent(factory, 0, myViewRef.injector);
  });

Answer №1

The process doesn't quite function in that manner. There is no TemplateRef connected to any DOM element. TemplateRef is a construct generated by the <template> tag and exclusively used with the <template> tag.

It's challenging to offer alternative suggestions without having a clear understanding of what you mean by "I need to dynamically load a component into an HTML Element that might be anywhere inside my app component."

Do you need to insert a component into a specific location within another component's content?

If that's the case, simply add a #loadLocation attribute to an element in your component's content, and use this code snippet within your component to dynamically load your custom component into that designated element.

@ContentChild('loadLocation',{read: ViewContainerRef}) loadLocation: ViewContainerRef;

constructor(private componentFactoryResolver: ComponentFactoryResolver) {}

ngAfterContentInit() {
  if (!this.loadLocation) {
    return;
  }
  let componentFactory = this.componentFactoryResolver.resolve(myComponent);
  let newComponent = this.loadLocation.createComponent(componentFactory);
}
