How to use Angular 2 to communicate with JavaScript API whenever the router switches to

I am currently working on an Angular2 component that has a template which relies on JavaScript calls to load various components such as Facebook, Google Maps, and custom scripts.

The necessary scripts are already loaded in the index.html file, so all I need to do is call them to update their contents.

My question is: How can I call my JavaScript methods in Angular2 each time the view is changed?

For example, consider the following code snippet from myJavaScript.js:


loadData(){
...
}
$(document).load(loadData());

My goal is to trigger the loadData() function every time the router revisits my component. How can this be achieved in Angular2?

Answer №1

At the beginning of your code

declare function foo();///js function
This assumes that your JavaScript function is accessible as a global object. Next, you should call this function foo within the ngOnInit() lifecycle method of your component.
