Angular2: Disable a formbuilder's element

问题

I'm trying to disable an element of my formbuilder after the declaration because I have to validate something once my view is loaded, so this is my formBuilder declaration.

ionViewDidLoad() {
  this.purchaseDataForm = this.formBuilder.group({
    kms: ['', Validators.required],
    lts: ['', Validators.required],
    price: ['', Validators.required],
    total: ['', Validators.required]
  });
}

I have no idea how to do that because I want to disable the total element once finished my local validation. I hope you can help me.

Thanks!

this.purchaseDataForm.get('price').disable() // .enable()
