Angular 2 表单控件更新

Question

How do I apply [ngModel] to the FormControl. Lets say I have a form with some required fields, based on the changes in the selectbox I want to update the form Control?

Answer 1

It's best not to mix the two types of form reactive vs template meaning: FormControl with ngModel

if you're using reactive, you can use this to update a form controls value this.myForm.get('SomeFormControl').patchValue('new value);
