browserAction.getTitle()

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.

Syntax

js
let gettingTitle = browser.browserAction.getTitle(
  details               // object
)

Parameters

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.

Return value

A Promise that will be fulfilled with a string containing the browser action's title.

Examples

This code switches the title between "this" and "that" each time the user clicks the browser action:

js
function toggleTitle(title) {
  if (title === "this") {
    browser.browserAction.setTitle({ title: "that" });
  } else {
    browser.browserAction.setTitle({ title: "this" });
  }
}

browser.browserAction.onClicked.addListener(() => {
  let gettingTitle = browser.browserAction.getTitle({});
  gettingTitle.then(toggleTitle);
});
