Contoh

Contoh berikut menunjukkan cara mengonfigurasi dan memulai operasi unggah multi-bagian.

var upload = null;
var promise = null;

function MultipartUpload (uriString, files) {
    try {

        var uri = Windows.Foundation.Uri(uriString);
        var uploader = new Windows.Networking.BackgroundTransfer.BackgroundUploader();
        var contentParts = [];
        files.forEach(function (file, index) {
            var part = new Windows.Networking.BackgroundTransfer.BackgroundTransferContentPart("File" + index, file.name);
            part.setFile(file);
            contentParts.push(part);
        });

        // Create a new upload operation.
        uploader.createUploadAsync(uri, contentParts).then(function (uploadOperation) {
            // Start the upload and persist the promise to be able to cancel the upload.
            upload = uploadOperation;
            promise = uploadOperation.startAsync().then(complete, error, progress);
        });
    } catch (err) {
        displayError(err);
    }
};
