Dynamic add component using gridstack and angular2? Jquery $.parseHTML does not work

I have the following jsfiddle

I want to be able to stick my custom component into a specific grid (e.g. "")

Right now without Angular2, I just use:

var el = $.parseHTML("<div><div class=\"grid-stack-item-content\" data-id=\""+id+"\"/><div/>");
this.grid.add_widget(el, 0, 0, 6, 5, true);

The issue is, I have no idea how I could do something like:

var el = $.parseAndCompileHTMLWithComponent("<div><div class=\"grid-stack-item-content\" data-id=\""+id+"\"/><fancy-button></fancy-button><div/>");
this.grid.add_widget(el, 0, 0, 6, 5, true);

In angular1, I know there is a compile, but in angular2, there is no such thing.

My fancy-button component is straightforward and is as follows:

@Component({
  selector: 'fancy-button',
  template: `<button>clickme</button>`
})
export class FancyButton {}

How can I dynamically add the fancy-button component?

Solution

  • The easist way to add fancy-button component dynamically might be as follows:

    1) Add component to entryComponents array of your module

    @NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent, GridStackComponent, FancyButtonComponent ],
  entryComponents: [ FancyButtonComponent ], // <== here
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

    2) Get root node from compiled component

    constructor(private vcRef: ViewContainerRef, private componentFactoryResolver: ComponentFactoryResolver) { }

getRootNodeFromParsedComponent(component) {
  const componentFactory = this.componentFactoryResolver.resolveComponentFactory(component);
  const ref = this.vcRef.createComponent(componentFactory, this.vcRef.length, this.vcRef.injector);
  const hostView = <EmbeddedViewRef<any>>ref.hostView;
  return hostView.rootNodes[0];
}

    3) Use it anywhere

    const fancyBoxElement = this.getRootNodeFromParsedComponent(FancyBoxComponent);  
$('#someId').append(fancyBoxElement);
