Gets the browser action's title.
Just as you can set the title on a per-tab basis using
browserAction.setTitle()
, so you can retrieve a tab-specific title by passing the tab's ID into this function.
This is an asynchronous function that returns a
Promise
.
var gettingTitle = browser.browserAction.getTitle(
details
// object
)
details
An object with the following properties:
tabId
可选
integer
. Specify the tab to get the title from.
windowId
可选
integer
. Specify the window to get the title from.
windowId
and
tabId
are both supplied, the function fails and the promise it returns is rejected.
windowId
and
tabId
are both omitted, the global title is returned.
A
Promise
that will be fulfilled with a string containing the browser action's title.
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);
});
