Properties

_REGEX_HASH

RegExp protected final static

Regular expression used to parse location hash/query strings.

hashPrefix

String static

Prefix to prepend when setting the hash fragment. For example, if the prefix is ! and the hash fragment is set to #foo=bar&baz=quux, the final hash fragment in the URL will become #!foo=bar&baz=quux. This can be used to help make an Ajax application crawlable in accordance with Google's guidelines at http://code.google.com/web/ajaxcrawling/ .

Note that this prefix applies to all HistoryHash instances. It's not possible for individual instances to use their own prefixes since they all operate on the same URL.

Default: ''

SRC_HASH

String final static

Constant used to identify state changes originating from hashchange events.
