I'm a relative newbie when it comes to Angular and I'm building an Angular app and am looking to format an input field where a user inputs their income and it needs to be formatted so that it both has a GBP symbol before it and with commas separating out the value into thousands.
So, for example, a user adds their income as 34000 and it will be displayed as £34,000
I'm trying to use pipes to help me achieve this and I've tried using the CurrencyPipe and regular Pipes and I get the same issues with both. So, for example, with the number pipe I'll have:
<input type="number" (change)="getApp1income()" (keyup)="getApp1income()" [(ngModel)]="app1income | number" [ngModelOptions]="{standalone: true}" min="0" step="500" data-number-to-fixed="2" data-number-stepfactor="500" />
However, this gives me the following error:
Uncaught Error: Template parse errors:
Parser Error: Cannot have a pipe in an action expression at column 14 in [app1income | number=$event]
I'll get the same error when using CurrencyPipe as well. I think this has to do with the fact with the fact that ngModel is using 2-way data-binding as I'm using the value entered elsewhere. But I can't seem to find a solution at all and I've looked at various similar issues both on here and elsewhere.
Any help would be appreciated.
