Email ID should accept special character also-CodePudding

Please help me to validate the entered email so that the input box should accept all special characters. This is email ID: sokoł[email protected] We need to validate this email ID.

ts file:

 this.fromEmail = this.fb.control('', [
      Validators.required,
      Validators.email,
    ]);

I need regex to validation.

CodePudding user response：

Angular comes with built in validators when creating a FormControl.

public email_id = new FormControl('', Validators.email);

This should accept your above example as a valid email. I would recommend reading up on FormControl and validation events.

Here I have provided a sample code for email validation in angular for your reference
