<input type="text" formControlName="exposure" type="hidden"> <label>{{exposure}}</label> If I use the formControlName in the input the value is correct.
How do I get the value of exposure in template? Its blank in the label

[formControl] assigns a reference to the FormControl instance you created to the FormControlDirective . formControlName assigns a string for the forms module to look up the control by name. If you create variables for the controls, you also don't need the .
The name corresponds to a key in the parent FormGroup or FormArray . Accepts a name as a string or a number. The name in the form of a string is useful for individual forms, while the numerical form allows for form controls to be bound to indices when iterating over controls in a FormArray . @Input('disabled')
You can also create your own custom components (or directives) that can be bound to form controls—if they implement ControlValueAccessor interface. Angular has built-in ControlValueAccessor implementations for <input> , <textarea> , etc, but not for <div> .
The
formControlNamedirective is designed to be used with a parentFormGroupDirective(selector:[formGroup]).It accepts the string name of the
FormControlinstance you want to link, and will look for aFormControlregistered with that name in the closestFormGrouporFormArrayabove it.
Use form.get('exposure').value to get the control value.
Example:
<form [formGroup]="form"> <input type="text" formControlName="exposure" type="hidden"> <label>{{ form.get('exposure').value }}</label> </form> In your component class, define a getter property representing your form control:
export class MyComponent { form = new FormGroup({ exposure: new FormControl('') }); get exposure(): FormControl { return this.form.get('exposure'); } Then, in your component template, you can reference exposure:
<input type="text" formControlName="exposure" type="hidden"> <label>{{exposure.value}}</label> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
