How to get ngModel value in TypeScript file?

To get the value of ngModel in a TypeScript file, you can use angular’s ViewChild decorator along with ElementRef to access the value of the input field. Here’s how you can do it:

“`typescript
import { Component, ViewChild, ElementRef } from ‘@angular/core’;

@Component({
selector: ‘app-example’,
templateUrl: ‘./example.component.html’,
styleUrls: [‘./example.component.css’]
})
export class ExampleComponent {
@ViewChild(‘inputField’) inputField: ElementRef;

getValue() {
const value = this.inputField.nativeElement.value;
console.log(value);
}
}
“`

In the above code snippet, we are using ViewChild decorator to get a reference to the input field with the template variable `#inputField`. We then use `ElementRef` to access the nativeElement of the input field and retrieve its value.

**const value = this.inputField.nativeElement.value;**

This line of code is where we are actually getting the ngModel value in TypeScript file.
