Gets the current browser window, passing its details into a callback.
The "current" window is not necessarily the same as the currently focused window. If this function is called from a background script, then it returns the currently focused window. But if it is called from a script whose document is associated with a particular browser window, then it returns that browser window. For example, if the browser is displaying a sidebar, then every browser window has its own instance of the sidebar document. If a script running in the sidebar document calls
getCurrent()
, then it will return that sidebar document's window.
This is an asynchronous function that returns a
Promise
.
var gettingCurrent = browser.windows.getCurrent(
getInfo
// optional object
)
getInfo
可选
对象
.
populate
可选
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 or
host permissions
that match the tab's URL.
windowTypes
可选
An
array
of
objects. If set, the
windows.WindowType
windows.Window
returned will be filtered based on its type. If unset the default filter is set to
['normal', 'panel', 'popup']
，采用
'panel'
window types limited to the extension's own windows.
注意：
If supplied, the
windowTypes
component of
getInfo
is ignored. The use of
windowTypes
has been deprecated as of Firefox 62.
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.
BCD tables only load in the browser
When the user clicks a browser action's icon, this example gets the current window and logs the URLs of the tabs it contains. Note that you'll need the "tabs" permission or matching host permissions to access tab URLs.
function logTabs(windowInfo) {
for (let tabInfo of windowInfo.tabs) {
console.log(tabInfo.url);
}
}
function onError(error) {
console.log(`Error: ${error}`);
}
browser.browserAction.onClicked.addListener((tab) => {
var getting = browser.windows.getCurrent({populate: true});
getting.then(logTabs, onError);
});
