Angular: Get Validators in FormGroup/FormControl | Quick Guide

If you're working with Angular forms, you may need to access the validators for a FormGroup or FormControl. This can be useful for displaying error messages or checking the validity of the form. Here's a quick guide on how to do it.

To get the validators for a FormGroup, you can use the `get` method to access the FormControl and then use the `validator` property to get the validators. Here's an example:


const formGroup = new FormGroup({
  email: new FormControl('', [Validators.required, Validators.email]),
  password: new FormControl('', Validators.required)
});

const emailValidators = formGroup.get('email').validator;
const passwordValidators = formGroup.get('password').validator;

In this example, we create a FormGroup with two FormControls, one for email and one for password. We pass an array of validators to each FormControl. Then, we use the `get` method of the FormGroup to access each FormControl and get the validators using the `validator` property.

To get the validators for a single FormControl, you can simply use the `validator` property of the FormControl. Here's an example:


const emailFormControl = new FormControl('', [Validators.required, Validators.email]);
const emailValidators = emailFormControl.validator;

In this example, we create a single FormControl for email with an array of validators. Then, we get the validators using the `validator` property of the FormControl.

That's it! With these quick tips, you can easily access the validators for your Angular forms and use them to display error messages or check the validity of the form.
