Gets details about a window, given its ID. The details are passed into a callback.
This is an asynchronous function that returns a
Promise
.
var getting = browser.windows.get(
windowId
,
// integer
getInfo
// optional object
)
windowId
integer
. The ID of the window object you want returned.
getInfo
可选
对象
. Contains options to filter the type of window.
populate
可选
boolean
。若
true
，
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 or a matching
host permission
.
windowTypes
可选
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']
，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
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.
注意：
This example is a bit unrealistic: in this situation you would more probably use
windows.getCurrent()
.
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);
});
