Angular 2: Iterate over reactive form controls

Question

I would like to markAsDirty all the controls inside of a FormGroup.

Answer 1

I create this function to make it* I have a control with name 'order', and pass index to him.

{"conditionGroups": [
   {
     "order": null,
     "conditions": []
   }
  ]
}


updateFormData() {
    const control = this.form.controls['conditionGroups'];  
    control.value.map((x,index)=>{
    x.order = index; 
 })
