如何在angular 4中链接JavaScript文件？

<script src="assets/script.js"></script>

"scripts": [
  "src/assets/script.js"
]

// script.js
export class ScriptService {
  // JavaScript code here
}

// app.module.ts
import { ScriptService } from './script.js';

@NgModule({
  providers: [ScriptService]
})
export class AppModule { }

// app.component.ts
import { Component } from '@angular/core';
import { ScriptService } from './script.js';

@Component({
  selector: 'app-root',
  template: '<button (click)="runScript()">Run Script</button>'
})
export class AppComponent {
  constructor(private scriptService: ScriptService) { }

  runScript() {
    // Access JavaScript code from the service
  }
}
