URL: username property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.

Note: This feature is available in Web Workers.

The username property of the URL interface is a string containing the username component of the URL. If the URL does not have a username, this property contains an empty string, "".

This property can be set to change the username of the URL. If the URL has no host or its scheme is file:, then setting this property has no effect.

The username is percent-encoded when setting but not percent-decoded when reading.

Value

A string.
