What is the method for accessing global variables and functions within JavaScript scripts imported from the index.html file and utilizing them in a component?

In my Angular 6 project, I am facing an issue with accessing a private JavaScript library that is imported in the index.html file. The functions in this library are globally scoped, but when I try to access them inside a component, Angular does not recognize them and no error is displayed.

index.html
.....
<script src="https://somefile.js type="text/javascript" charset="utf-8">
.....

// contains a function 
doXYZ()  within the global namespace

somecomponent.ts
......

ngOnInit() {
    doXYZ()  //attempting to call the globally imported function
}
......

ERROR: When using ng serve, 'Cannot find name doXYZ' is displayed.

Answer №1

If you need to reach the global namespace, you can do so using the window object.

To access your specific function, try this method:

window['executeFunctionXYZ']();

The window object is universally available for use.
