Trigger file selection and upload entirely from JavaScript code. Use browse() to open the file dialog and startUpload() to begin uploading.
var uploader = AjaxUploader.create(element, {
multiple: true,
autoUpload: false,
showProgress: true
});
// Programmatic control
uploader.browse(); // Open file dialog
uploader.startUpload(); // Start uploading queued files
uploader.clearQueue(); // Remove all queued files
