I am working with Angular 11 and came across two way binding for quantity field which is an input field of the type number. Problem arrives when I try to use backspace for the quantity field input. It gives junk values which are then displayed with the correct value.
.html file
<button (click)="addProductToCart(product,1)">
<i ></i></button>
<input type="number" [ngModel]="product.quantity" (ngModelChange)="addProductToCart(product,$event)" id="prod-qty">
<button (click)="addProductToCart(product,-1)">
<i ></i></button>
.ts file
addProductToCart(pr: any, q: any){
pr.quantity=pr.quantity Number(q);
}
Is there any workaround for this issue?? Please do let me know
CodePudding user response:
You need to use two ways binding: [(ngModel)]="binding"
.
Your input should be:
<input type="number" [(ngModel)]="product.quantity" id="prod-qty">
