let gettingTitle = browser.action.getTitle(
details // object
)
details
An object with the following properties:
tabId
Optional
integer
. Specify the tab to get the title from.
windowId
Optional
integer
. Specify the window to get the title from.
If windowId
and tabId
are both supplied, the function fails and the promise it returns is rejected.
If 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.
This code switches the title between "this" and "that" each time the user clicks the browser action:
function toggleTitle(title) {
if (title === "this") {
browser.action.setTitle({ title: "that" });
} else {
browser.action.setTitle({ title: "this" });
}
}
browser.action.onClicked.addListener(() => {
let gettingTitle = browser.action.getTitle({});
gettingTitle.then(toggleTitle);
});
