Angular 4 - get input value

Question

I would like to know how to get the value from an input on angular 4. I looked over the documentation on angular and the example with the key event doesn\'t work very well for m

Answer 1

I think you were planning to use Angular template reference variable based on your html template.

 // in html
 <input #nameInput type="text" class="form-control" placeholder=''/>

 // in add-player.ts file
 import { OnInit, ViewChild, ElementRef } from '@angular/core';

 export class AddPlayerComponent implements OnInit {
   @ViewChild('nameInput') nameInput: ElementRef;

   constructor() { }

   ngOnInit() { }

   addPlayer() {
     // you can access the input value via the following syntax.
     console.log('player name: ', this.nameInput.nativeElement.value);
   }
 }

If you dont want to use two way data binding. You can do this.

In HTML

<form (ngSubmit)="onSubmit($event)">
   <input name="player" value="Name">
</form>

In component

onSubmit(event: any) {
   return event.target.player.value;
}

html

<input type="hidden" #fondovalor value="valores">
     <button (click)="getFotoFondo()">Obtener</button>

ts

@ViewChild('fondovalor') fondovalor:ElementRef;

getFotoFondo(){ 
        const valueInput = this.fondovalor.nativeElement.value
}
