Display value inside input

问题

I have designed my form till here. Now I further want to show the amount of the particular row over there in the row in Amounts column.

<input type="text" class="form-control" formControlName="itemamt" readonly value="{{itemrow.get('itemqty').value * itemrow.get('itemrate').value}}">

回答1:

To pass FormControll Value inside FormArray you can do something like this with angular,

form = new FormGroup({
     name: new FormControl('Name'),
     username: new FormArray([
                  new FormControl("value"),
                  {firstName:"Andrew", lastName:"Donald"},
                  {firstName:"Charles", lastName:"Jackson"}
                ])
   });

Hope this might be helpfull for you.
