parseHash
-
hash

Parameters:
-
hash
String(optional) location hash string
Returns:
object of parsed key/value parameter pairs
replaceHash
-
hash
Replaces the browser's current location hash with the specified hash
and removes all forward navigation states, without creating a new browser
history entry. Automatically prepends the hashPrefix
if one
is set.
Parameters:
-
hash
Stringnew location hash
setHash
-
hash
Sets the browser's location hash to the specified string. Automatically
prepends the hashPrefix
if one is set.
Parameters:
-
hash
Stringnew location hash
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.
