What is the best way to refresh the script located within the head tag of an index.html file in an Angular

I've been looking for solutions, but I can't seem to find one.

In my index.html file, I've placed some script within the head tag (even above the </body> tag) and included a $(document).ready function.

The issue I'm facing is that the script only works when the server starts. If I navigate away from the component where the script is used and return, the script ceases to work until I refresh the page.

My question is, how can I refresh just the index.html without refreshing the entire application? Is there a way to reuse my script code repeatedly without encountering this issue?

I attempted to import an external js file in the index.html, but the function was not invoked. Likewise, trying to write JS code within the AfterViewInit lifecycle hook also proved unsuccessful.

Understanding how $(document).ready functions is crucial. This function is called once your document has finished loading, whether you are loading, refreshing, or reloading the page.

It's important to consider what the script is actually accomplishing. If it involves setting global scopes, consider abstracting the logic into a service and calling it in each component where needed. Ensure that you initialize/call your script/logic before your components load.

export class DataService {

  constructor() { }

  myData() {
    return 'This is my data!';
  }

}

export class AppComponent {

  constructor(private dataService:DataService) {

  }

  ngOnInit() {
    this.dataService.myData();
  }

}

If the script operates like a background thread that needs to constantly run, consider using the setInterval API in your AppComponent/ContainerComponent. This will ensure that your script remains active in the context.

ngOnInit() {
  this.id = setInterval(() => {
    this.Init(); 
  }, 1000);
}
