mailto -link not launching on iOS Web App

Question

I'm trying to launch a link with href="mailto:foo@bar.com" (also tried "mailto://foo@bar.com"). When I alert this.href, it returns the correct value, but nothing happens afterwards.

Is there a custom URL Scheme for Web Applications to launch Mail-program? This is working eg. with Maps, so I have no idea why same approach wouldn't work with E-mail.

Any suggestions?

Answer 1

I'm finding that this seems to work well with iOS in web-app mode. Works for MAILTO: and SMS: links that otherwise gave an error. Also does not open a new blank page like some "solutions".

<a href='#' onclick='window.open(`mailto:mail@example.com`, `_self`);'>Link text</a>
