URL: hash property

Baseline Widely available

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

Note: This feature is available in Web Workers.

The hash property of the URL interface is a string containing a "#" followed by the fragment identifier of the URL. If the URL does not have a fragment identifier, this property contains an empty string, "".

This property can be set to change the fragment identifier of the URL. When setting, a single "#" prefix is added to the provided value, if not already present. Setting it to "" removes the fragment identifier.

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

Value

A string.

Examples

const url = new URL(
  "https://developer.mozilla.org/en-US/docs/Web/API/URL/href#examples",
