Overview

The widget object provides functionality for accessing an extension's metadata and persistently-stored data. It can be accessed from any of the extension's environments, such as background process, popup window, injected script or preferences page. Note that the widget object is readonly and therefore cannot be used to edit or store values on-the-fly.

Example

The below example shows how simple it is to access data within the widget object.

//
// The preferences page (e.g. options.js)
//

var footer = 'This extension is the work of <a href="' + widget.authorHref + '">' + widget.author + '</a>';
document.body.innerHTML += footer;
