How to reset only specific fields of form in angular 5

Question

I have created a function in one of my component file that resets the form(myform):

`onSubmit() {
  if (this.myform.valid) {
    console.log(\"Form Submitted!\")         


        

Answer 1

try this:

this.myform.controls['comments'].reset()

Answer 2

In your html

<select formControlName="idSala" (change)="clearField(1)">
 <option value="">Selecione uma sala</option>
</select>

<input type="text" formControlName="titulo">

<input formControlName="dataHoraInicial" type="datetime-local">

TS

clearField(value) {
if (value == 1) {
  this.formularioDeAgendamentoSala.controls['titulo'].reset();
  this.formularioDeAgendamentoSala.controls['dataHoraInicial'].reset();
}

}

Answer 3

try this one:

  clearForm() {
    this.myForm.get('comments').reset();
    this.myForm.get('name').reset();
  }

and call this function where you submit form.

UPDATE:

I just had this issue and although the accepted answer works, it has some tslint warnings. I ended up doing:

this.myForm.get('formControlName').setValue(null);

I'm working with Angular 8.

And if you want to do it for several fields this works too:

private controlNames = ['nameOne', 'nameTwo'];

this.controlNames.map((value: string) => this.myForm.get(value).setValue(null));

Answer 5

Yes you can access the controls using this.myform.controls get the control and call reset() on it
