Example: validating mail addresses

For example, we validate a text field to input mail addresses. We need to write code for checking whether the mail addresses exist or not, but we can check format of them with validating input.

In this case, we check the addresses include at mark (@). If the addresses don’t include at mark, pass_mailvariable is true.

Mail : CKTextField {
  value    = mail
  validate = "mail =~ /[^@]+@(.+)/"
  pass     = pass_mail
}
