                            <button class="btn btn-outline" (click)="addtocart(this.productid)">Addtocart</button>
                        </p>
                    </div>
                </a>
            </div>

            <div class="col-lg-4 col-md-4 col-sm-12 col-xs-12">
                    <a href="#" class="card clickable">
                        <div class="card-img">
                            <img src="">
                        </div>
                        <div class="card-block">
<input type="hidden" name=""  value="vppp112ddddd" id="" #productid>
 <input type="hidden" name=""  value="product2" id="" #productname>
                            <p class="card-text">
                                <button class="btn btn-outline" (click)="addtocart()">Addtocart</button>
                            </p>
                        </div>
                    </a>
                </div>
    </div>

And this is my component.ts

export class Products  {

    addtocart(item1,item2,item3){
        alert(item.value);
        //alert("item added");
         this.cartservice.additems(item1,item2,item3);
        return false;
    }
    constructor(public cartservice:CartService){

    }}

I want to pass my hidden fields value to component.ts ,the products will be displayed dynamically ,from database any help will be really appreciated

Answer 1

Although you can use ngModel, IMO it is better to use form controls. You'll get all power of the rxjs (via valueChanges), at least. To perform that, you should:

1. Import ReactiveFormsModule to your host module
2. Add a formCotrol directive to input - eg
3. Define form control in the component - public myControl = new FormControl()

Then work with it as described in docs
