Make a Copy of an Email

Demonstrates the Chilkat Email.MakeCopy method, which copies the entire state of this email into another Email object — message content, recipients, headers, body representations, attachments, and related items. This example copies an email and reads a couple of fields from the copy.

Background: A deep copy gives you an independent duplicate: changes to one object do not affect the other. This is handy for template-and-tweak workflows — build a base message once, copy it per recipient, then vary only the recipient or a few fields — without risk of one send's edits bleeding into the next.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

//  Demonstrates the MakeCopy method, which copies the entire state of this email into
//  another Email object -- message content, recipients, headers, bodies, attachments, and
//  related items.

var email = new CkEmail();
email.Subject = "Original";
email.From = "alice@example.com";
email.AddTo("Bob","bob@example.com");
email.Body = "Original body.";

//  Copy the entire email into a new Email object.
var copy = new CkEmail();

success = email.MakeCopy(copy);
if (success == false) {
    console.log(email.LastErrorText);
    return true;
}

console.log("Copy subject: " + copy.Subject);
console.log("Copy NumTo: " + copy.NumTo);
