Gets the sidebar's title.
Just as you can set the title on a per-tab basis using
sidebarAction.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.sidebarAction.getTitle(
details
// object
)
details
对象
. An object with the following properties:
tabId
可选
integer
. Get the title for the sidebar specific to the given tab.
windowId
可选
integer
. Get the title for the sidebar specific to the given window.
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 sidebar'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.sidebarAction.setTitle({title: "that"});
} else {
browser.sidebarAction.setTitle({title: "this"});
}
}
browser.browserAction.onClicked.addListener(() => {
var gettingTitle = browser.sidebarAction.getTitle({});
gettingTitle.then(toggleTitle);
});
