I need to attribute action url to be composed of "url" + variable.
Like this:
<script>
var domain = "@example.com";</script><body><form action=("https://login.example.com/&" + domain) id="login_form" method="get"><input type="text" name="username"><button type="submit" id="submit">Log in</button></form>I need to make label with lastname and send the label as lastname@example.com by this form.
