Sets the browser action's title. The title is displayed in a tooltip over the browser action's icon. You can pass a
tabId
in or a
windowId
as an optional parameter — if you do this then the title is changed only for the given tab or the given window. Tabs or windows without a specific title will inherit the global title text, which defaults to the
default_title
or
名称
specified in the manifest.
browser.browserAction.setTitle(
details
// object
)
details
对象
. The new title and optionally the ID of the tab or window to target.
title
string
or
null
. The string the browser action should display when moused over.
若
title
is an empty string, the used title will be the extension name, but
browserAction.getTitle
will still provide the empty string.
若
title
is
null
:
tabId
is specified, and the tab has a tab-specific title set, then the tab will inherit the title from the window to which it belongs.
windowId
is specified, and the window has a window-specific title set, then the window will inherit the global title.
tabId
可选
integer
. Sets the title only for the given tab.
windowId
可选
integer
. Sets the title for the given window.
windowId
and
tabId
are both supplied, the function fails and the title is not set.
windowId
and
tabId
are both omitted, the global title is set.
BCD tables only load in the browser
This code switches the title between "this" and "that" each time the user clicks the browser action:
function toggleTitle(title) {
if (title == "this") {
browser.browserAction.setTitle({title: "that"});
} else {
browser.browserAction.setTitle({title: "this"});
}
}
browser.browserAction.onClicked.addListener(() => {
var gettingTitle = browser.browserAction.getTitle({});
gettingTitle.then(toggleTitle);
});
