Wenn Sie versuchen, eine etwas kanonische (oder zumindest reichhaltige) Antwort zu finden, ist dies das Javascript für wpse142997.jsdas untergeordnete Vorlagenverzeichnis:

if ( typeof wp.Uploaded === 'undefined') return;
// Keep track of files uploaded.
wp.Uploader.queue.on( 'add', function ( attachment ) {
attachments_uploaded.push( attachment );
});
// The Uploader (in wp-includes/js/plupload/wp-plupload.js) resets the queue when all uploads are complete.
wp.Uploader.queue.on( 'reset', function () {

Das Javascript versucht, so weit ich es verstehe, dem WP Media Modal-Weg zu folgen, der nur teilweise ist. Es erstellt eine media.view.Attachmentund verwendet eine wp.templateVorlage. Es gibt ein paar hacky Bits - insbesondere die Sidebar über eine lange Reichweite in das Frame-Objekt zu bekommen, scheint verdächtig (und wurde erst nach langem Stöbern gefunden).
