<h1>goog.History</h1>
|
||||
<p>This page demonstrates the goog.History object which can create new browser
|
||||
history entries without leaving the page. This version uses the hash portion of
|
||||
the URL to make the history state available to the user. These URLs can be
|
||||
bookmarked, edited, pasted in emails, etc., just like normal URLs. The browser's
|
||||
back and forward buttons will navigate between the visited history states.</p>
|
||||
|
||||
<p>Try following the hash links below, or updating the location with your own
|
||||
tokens. Replacing the token will update the page address without appending a
|
||||
new history entry.</p>

|

|

<p>The state should be correctly restored after you
|
||||
<a href="http://www.google.com/">leave the page</a> and hit the back button.</p>
|
||||
|
||||
<p>The history object can also be created so that the history state is not
|
||||
user-visible/modifiable.
|
||||
See <a href="history2.html#came from history 1">history2.html</a> for a demo.
|
||||
To see visible/modifiable history work when the goog.History code itself is
|
||||
loaded inside a hidden iframe,
|
||||
see <a href="history3.html#came from history 1">history3.html</a>.
