I am looking for a solution for following problem:

I have a form like this:

<form (ngSubmit)="submit(f.form)" #f="ngForm">
 <label>Name</label>
 <input type="text" name="name" required />
 ...
 <button type="submit">Submit</button>
</form>

I process it like this:

submit(f: FormGroup): void {
 Object.keys(form.controls).forEach(key => 

 const controlErrors: ValidationErrors = form.get(key).errors;
 if (controlErrors != null) 
 Object.keys(controlErrors).forEach(keyError => 
 console.log('Key control: ' + key + ', keyError: ' + keyError + ', err value: ', controlErrors[keyError]);
 );
 
);

So I output to the console all the validation errors in a generic way. In this processing I need to be able to access value of a label which is next to the input to get its value instead of key. So I can make a message saying 'labelValue is required.'. How can I access value of label. I cannot make it a ViewChild as I am looking for a generic solution and I cannot make a ViewChild for every label element in form.

  Try accessing the native element from the form control. It might help.
