Create a multipart/mixed MIME Entity

Demonstrates the Chilkat Mime.NewMultipartMixed method, which initializes the object as an empty multipart/mixed entity, clearing any existing content. It takes no arguments; child parts are then appended.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: multipart/mixed is the container for independent parts shown one after another — the classic "message body plus attachments" layout. Each child is its own distinct content, unlike multipart/alternative (competing renderings of the same thing) or multipart/related (a part and its embedded resources). Start here, then AppendPart a body and AppendPartFromFile the attachments.

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.

JavaScript

var success = false;

//  Demonstrates the Mime.NewMultipartMixed method, which initializes the object as an empty

//  arguments.

var mime = new CkMime();

success = mime.NewMultipartMixed();
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

//  Append child parts.  multipart/mixed is the container for a message body plus attachments.
var bodyPart = new CkMime();
success = bodyPart.SetBodyFromPlainText("See the attached report.");
if (success == false) {
    console.log(bodyPart.LastErrorText);
    return;
}

success = mime.AppendPart(bodyPart);
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

success = mime.AppendPartFromFile("qa_data/report.pdf");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log("Number of parts: " + mime.NumParts);
