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.
