Add a ChangeDetectorRef to force your app to check any changes in your component
by doing this
constructor(
private changeRef: ChangeDetectorRef
){
let node = document.createElement('script');
node.src = 'https://apis.google.com/js/client.js?onload=__onGoogleLoaded';
node.type = 'text/javascript';
document.getElementsByTagName('head')[0].appendChild(node);
window['__onGoogleLoaded'] = (ev) =>{
console.log('here!!!!');// <----------------------------WORKING
this.loaded = true;// <---------------------------------NOT WORKING
this.changeRef.detectChanges(); <<---------------------------------- add this one
}
//this.loaded = true; <<----------------------------------WORKING
}

I'm trying to load Google API inside an angular6 app. After the load event has been fired, I can't really change anything in my component.
Have a look at the comments at the last 3 lines of the script
@Component({ selector: 'my-app', template: '{{loaded}}', }) export class AppComponent { loaded = false; constructor(){ let node = document.createElement('script'); node.src = 'https://apis.google.com/js/client.js?onload=__onGoogleLoaded'; node.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(node); window['__onGoogleLoaded'] = (ev) =>{ console.log('here!!!!');// <----------------------------WORKING this.loaded = true;// <---------------------------------NOT WORKING } //this.loaded = true; <<----------------------------------WORKING } }
