Examples

The following JavaScript example shows how to invoke the CreateObject method and create a Downloader:

JavaScript
// Event handler for initializing and executing a download request. function onMouseLeftButtonUp(sender, eventArgs) { // Retrieve a reference to the plug-in. var slPlugin = sender.getHost(); // Create a Downloader object. var downloader = slPlugin.createObject("downloader"); // Add DownloadProgressChanged and Completed events. downloader.addEventListener("downloadProgressChanged", onDownloadProgressChanged); downloader.addEventListener("completed", onCompleted); // Initialize the Downloader request. // NOTE: downloader APIs disallow file:\\ scheme // you must run this sample over localhost: or off a server or the following call will fail downloader.open("GET", "promo.png"); // Execute the Downloader request. downloader.send(); }

JavaScript

// Event handler for initializing and executing a download request.
function onMouseLeftButtonUp(sender, eventArgs)
{
    // Retrieve a reference to the plug-in.
    var slPlugin = sender.getHost();

    // Create a Downloader object.
    var downloader = slPlugin.createObject("downloader");

    // Add DownloadProgressChanged and Completed events.
    downloader.addEventListener("downloadProgressChanged", onDownloadProgressChanged);
    downloader.addEventListener("completed", onCompleted);
