Document: title property
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).
