Class HistoryHash
- extends HistoryBase
Provides browser history management backed by
window.location.hash, as well as convenience methods for working
with the location hash and a synthetic hashchange event that
normalizes differences across browsers.
Constructor
HistoryHash
(
config
)
- Parameters:
-
config
<Object>
(optional) Configuration object. See the HistoryBase
documentation for details.
Properties
_REGEX_HASH
- protected static final RegExp
Regular expression used to parse location hash/query strings.
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 Value: ''
SRC_HASH
- static final String
Constant used to identify state changes originating from
hashchange events.
