Within a directive, I am utilizing an input with a dynamic name structure:
<input class="input-field" name="{{name}}" type="number" ... />
My goal is to retrieve the $error variable of the form from inside the directive. Can this be achieved by using something like form.{{name}}.$error.number?
Is there a method to accomplish this task?
To gain access to the form located in the parent scope, you must pass the form to your directive. Make sure to indicate that you want two-way binding (using =) when defining your directive.
Check out https://docs.angularjs.org/guide/directive, specifically the section on isolating the scope for valuable information.
