windows.getLastFocused()

Gets the window that was most recently focused — typically the window 'on top' — and passes it into a callback.

Syntax

chrome.windows.getLastFocused(
  getInfo,               // optional object
  function(window) {...} // function
)

This API is also available as browser.windows.getLastFocused() in a version that returns a promise.

Parameters

getInfoOptional

object.

populateOptional

boolean. If true, the windows.Window object will have a tabs property that contains a list of tabs.Tab objects representing the tabs 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

An 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.

callback

function. The function is passed the following arguments:

window

A windows.Window object representing the last focused window.

Examples

Get the last focused window, and log the tabs it contains. Note that you'll need the "tabs" permission to access tab URLs.

function logTabs(windowInfo) {
  if (chrome.runtime.lastError) {
    console.log(chrome.runtime.lastError);
  } else {
    for (tabInfo of windowInfo.tabs) {
      console.log(tabInfo.url);
    }
  }
}

chrome.windows.getLastFocused({populate: true}, logTabs);
