Angular form validation priority

[ivang...@gmail.com]

Hello,

I'm trying to add a custom validator to an email input.

I want my validator to be executed after the angular email validation.

Is there a way to do this?

Thanks!

$parsers.push(yourValidationFunction);

Yes,

You've got a full control over order of validators as AngularJS keeps
all of them in a parserrs / formatters array. So you can decide where
in the array (at which stage of the validation pipeline) your
validator should end up.

For example, let's say that you write a validator to check if an
e-mail is unique and to do so you need to contact a server. But this
should be the last stage of the validation pipeline as there is no
point calling a server if an e-mail is not valid, right?

We are using this technique in the sample AngularJS app to make sure
that the server is called as late as possible:
https://github.com/angular-app/angular-app/blob/master/client/src/app/admin/users/admin-users-edit.js#L32

Hope this helps,
Pawel

Thank you both.

Actually, the use case you just described is what I was trying to do :)
