Call Pure Javascript Function From Angular 2 Component

Are you ready to take your Angular 2 development skills to the next level? In this guide, we'll walk you through the steps on how you can call a pure JavaScript function from an Angular 2 component.

First things first, let's clarify what a pure JavaScript function is. A pure JavaScript function is a function written in vanilla JavaScript, which means it doesn't rely on any external libraries or frameworks like Angular. Integrating these functions with your Angular 2 components can sometimes be a bit tricky, but fear not, we've got you covered.

To call a pure JavaScript function from an Angular 2 component, follow these simple steps:

1. Import the ViewChild decorator: Before you can access an element in your template, you need to import the ViewChild decorator from '@angular/core'.

2. Set up a reference variable in your template: In your component's HTML template, add a reference variable to the element that you want to interact with. You can do this by using the `#` symbol followed by a name of your choice.

3. Access the element in your component: Use the ViewChild decorator to access the element in your component code. This will allow you to interact with the element directly in your Angular component.

4. Call the pure JavaScript function: Once you have a reference to the element, you can call your pure JavaScript function just like you would in a regular JavaScript file. Simply use the reference variable you created in your template to access the element and call the function.

import { Component, ViewChild, ElementRef } from '@angular/core';

@Component({
  selector: 'app-your-component',
  template: `
    <button>Click me</button>
  `
})
export class YourComponent {
  @ViewChild('myButton') myButton: ElementRef;

  callMyFunction() {
    // Call your pure JavaScript function here
  }
}

And that's it! By following these steps, you can seamlessly integrate pure JavaScript functions with your Angular 2 components. Remember, keeping your code clean and organized is key to ensuring smooth integration.

In conclusion, mixing pure JavaScript with Angular 2 doesn't have to be daunting. With a little bit of understanding and practice, you can easily call your JavaScript functions from your Angular components. So go ahead, give it a try, and elevate your Angular development skills to the next level! Happy coding!
