Angular 8/ Reactive Form - Converting result of checkbox event to a string value

Question

I have my Reactive form with field - Status (which can have values \'A\' or \'I\'):

this.form = this.formBuilder.group({
          result_info: this.formBuilder.         


        

Answer 1

a FormControl exist you has a input or not. I wrote yet in another answer (but I can not find it). Use a input with [ngModel] and (ngModelChange) to control the value of FormControl

If you use mat-checkbox use checked and change

In a FormArray it's the same imagine you has a form with a formArray, you defined in your .ts a function taht return the formArray

  get myformArray()
  {
    return this.form.get('formArray') as FormArray
  }

And your form like

    

        

            status
            
             
        

See that you use an input "ngModel" to control the "check" and a input with formControlName to control the name

You can be an example of all this in stackblitz
