Document: title property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The document.title property gets or sets the current title of the document. When present, it defaults to the value of the <title>.

Value

A string containing the document's title. If the title was overridden by setting document.title, it contains that value. Otherwise, it contains the title specified in the <title> element.

js
document.title = newTitle;

newTitle is the new title of the document. The assignment affects the return value of document.title, the title displayed for the document (e.g. in the titlebar of the window or tab), and it also affects the DOM of the document (e.g. the content of the <title> element in an HTML document).

Examples

html
<!doctype html>
<html lang="en-US">
  <head>
    <meta charset="UTF-8" />
    <title>Hello World!</title>
  </head>
  <body>
    <script>
      alert(document.title); // displays "Hello World!"
      document.title = "Goodbye World!";
      alert(document.title); // displays "Goodbye World!"
    </script>
  </body>
