Document: title property

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.

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

Assume the document's <head> looks like:

<head>
  <meta charset="UTF-8" />
  <title>Hello World!</title>
</head>

console.log(document.title); // "Hello World!"
document.title = "Goodbye World!"; // Page title changed
console.log(document.title); // "Goodbye World!"
