windows.get()

Gets details about a window, given its ID. The details are passed into a callback.

This is an asynchronous function that returns a Promise.

Syntax

var getting = browser.windows.get(
  windowId,              // integer
  getInfo                // optional object
)

Parameters

windowId

integer. The ID of the window object you want returned.

getInfoOptional

object. Contains options to filter the type of window.

populateOptional

boolean. If true, the windows.Window object will have a tabs property that contains a list of tabs.Tab objects representing the tabs open in the window. The Tab objects only contain the url, title and favIconUrl properties if the extension's manifest file includes the "tabs" permission.

windowTypesOptional

array of windows.WindowType objects. If set, the windows.Window returned will be filtered based on its type. If unset the default filter is set to ['normal', 'panel', 'popup'], with 'panel' window types limited to the extension's own windows.

Return value

A Promise that will be fulfilled with a windows.Window object containing the details of the window. If any error occurs, the promise will be rejected with an error message.

Examples

This example gets the current window and logs the URLs of the tabs it contains. Note that you'll need the "tabs" permission to access tab URLs.

function logTabs(windowInfo) {
  for (tabInfo of windowInfo.tabs) {
    console.log(tabInfo.url);
  }
}

function onError(error) {
  console.log(`Error: ${error}`);
}

browser.browserAction.onClicked.addListener((tab) => {
  var getting = browser.windows.get(tab.windowId, {populate: true});
  getting.then(logTabs, onError);
});
