Create a custom email validator with regex.
- [Instructor] Just like we created a custom…validator for password matching,…we will create one for email formatting as well.…Let's begin by creating a new email validation…function below our matching fields function.…(typing)…We'll call it email valid.…And we will return a function that takes…a form control object.…Which I'll call control.…(typing)…We will need to create a regular expression…that will define our expected email format.…
In order to get the regular expression,…I just did a search for email rejects online.…And I just grabbed the JavaScript version…from email rejects.com.…Next let's create a rejects variable,…and paste that in.…Then we will use a JavaScript rejects test function…to test against the email itself.…We will use an inline condition…and return null if the email…checks out against the rejects,…or an error object if it does not.…
(typing)…Now that we have our email validator,…let's plug it in to our form group.…Instead of passing in a single validator in our email,…let's pass in a list.…So I'll select the current validator from our email,…

Q: This course was updated on 10/17/2017. What changed?
A: We updated five videos to reflect changes to the setup and data retrieval and display processes in Angular 2. For example, instead of using a Git Angular template, the updated course uses the Angular CLI to generate a starting template, for a smooth runtime experience.
