Is there a way to reset a reactive form group into its initial values instead of get it empty using .reset() method ?

I have the following stackblitz, where the default selected value is Parent, and if the user change it to sister, and wants to get the form to initial value, click on reset button to do so.

Currently, I tried:

this.formGroup.reset();
//Or
this.formGroup.markAsPristine;
//Or
this.formGroup.markAsTouched

The .reset() reset the form completly.

P.S. Some people may say that the user can re-select the default value instead of clicking on reset button. But in my case, I have a huge user form where he needs to update his information, and he may needs to reset to initial values if he was mistaken in some values.


Please find the stackbliz here

Create a method setForm() which will be called in the constructor and reset()

setForm() {
  this.formGroup = this.fb.group({
    'family_relation': new FormControl(this.familyRelationArray[0]['family_relation_id'])
  });
}

(Remove the code from the constructor which set the initial values)

resetForm() now looks like:

reset() {

    //Or
    this.formGroup.markAsPristine;

        family_relation_type: 'Parent'

How to clear the form filled data after submitting the form in HTML , How do I reset the reactive form in angular 6? The validation checks if the form is empty.

You can save the form initial values:

this.initialValues = this.formGroup.value;

And then pass those values to the reset function:

this.formGroup.reset(this.initialValues);

Submitting & Resetting • Angular, When you need to reset it you just rebuild it. This way can be sure it's up to date. You can also keep values stored somewhere and reset form to those values. Say you're editing an item, when you reset you can revert to the original values, not just an empty form Angular Forms, check full syntax with explaination If template, then you need to set the model object to a default one (not necessarily empty). If reactive, then call a method which explictly empties each of form's value. After that, do the form.Reset to move it back to "pristine | unchanged" state, thus removing validators as well


There might be other ways of doing it, but I would do it using one of following methods:

Method 1: Passing values to the reset method.

reset() {
  this.formGroup.reset({family_relation: 1});
  //Or
  this.formGroup.markAsPristine;
  //Or
  this.formGroup.markAsTouched;
}

Method 2: Setting values

reset() {
  this.formGroup.reset();
  //Or
  this.formGroup.markAsPristine;
  //Or
  this.formGroup.markAsTouched;
  // this.formGroup.get('family_relation').setValue(1)
}
