Navigate the tab to a new URL, or modify other properties of the tab.
To use this function, pass the ID of the tab to update, and an
updateProperties
object containing the properties you want to update. Properties that are not specified in
updateProperties
are not modified.
This is an asynchronous function that returns a
Promise
.
var updating = browser.tabs.update(
tabId
,
// optional integer
updateProperties
// object
)
tabId
可选
integer
. Defaults to the selected tab of the current window.
updateProperties
对象
. The set of properties to update for this tab. To learn more about these properties, see the
tabs.Tab
文档编制。
active
可选
boolean
. Whether the tab should become active. Does not affect whether the window is focused (see
windows.update
). If
true
, non-active highlighted tabs will stop being highlighted. If
false
，什么都不做。
autoDiscardable
可选
boolean
. Whether the tab should be discarded automatically by the browser when resources are low.
highlighted
可选
boolean
. Adds or removes the tab from the current selection. If
true
and the tab is not highlighted, it will become active by default.
If you only want to highlight the tab without activating it, Firefox accepts setting
highlighted
to
true
and
active
to
false
. Other browsers may activate the tab even in this case.
loadReplace
可选
boolean
. Whether the new URL should replace the old URL in the tab's navigation history, as accessed via the "Back" button.
For example, suppose the user creates a new tab using Ctrl+T. By default, in Firefox, this would load "about:newtab". If your extension then updates this page using
tabs.update
, without
loadReplace
, the "Back" button will be enabled and will take the user back to "about:newtab". If the extension sets
loadReplace
, then the "Back" button will be disabled and it will be just as if the URL supplied by the extension was the first page visited in that tab.
Note though that the original URL will still appear in the browser's global history.
muted
可选
boolean
. Whether the tab should be muted.
openerTabId
可选
integer
. The ID of the tab that opened this tab. If specified, the opener tab must be in the same window as this tab.
pinned
可选
boolean
. Whether the tab should be pinned.
selected
可选
boolean
. Whether the tab should be selected. This property has been replaced by
active
and
highlighted
.
successorTabId
可选
integer
. The id of the ID of the tab's successor.
url
可选
string
. A URL to navigate the tab to.
For security reasons, in Firefox, this may not be a privileged URL. So passing any of the following URLs will fail, with
runtime.lastError
being set to an error message:
about:config
,
about:addons
,
about:debugging
,
about:newtab
). Non-privileged URLs (e.g.,
about:blank
) are allowed.
To load a page that's packaged with your extension, specify an absolute URL starting at the extension's manifest.json file. For example: '/path/to/my-page.html'. If you omit the leading '/', the URL is treated as a relative URL, and different browsers may construct different absolute URLs.
A
Promise
that will be fulfilled with a
tabs.Tab
object containing details about the updated tab. The
tabs.Tab
object doesn't contain
url
,
title
and
favIconUrl
unless matching
host permissions
或
"tabs"
permission has been requested. If the tab could not be found or some other error occurs, the promise will be rejected with an error message.
Navigate the active tab in the current window to https://developer.mozilla.org:
function onUpdated(tab) {
console.log(`Updated tab: ${tab.id}`);
}
function onError(error) {
console.log(`Error: ${error}`);
}
var updating = browser.tabs.update({url: "https://developer.mozilla.org"});
updating.then(onUpdated, onError);
Activate the first tab in the current window, and navigate it to https://developer.mozilla.org:
function onUpdated(tab) {
console.log(`Updated tab: ${tab.id}`);
}
function onError(error) {
console.log(`Error: ${error}`);
}
function updateFirstTab(tabs) {
var updating = browser.tabs.update(tabs[0].id, {
active: true,
url: "https://developer.mozilla.org"
});
updating.then(onUpdated, onError);
}
var querying = browser.tabs.query({currentWindow:true});
querying.then(updateFirstTab, onError);
BCD tables only load in the browser
