<p>This page demonstrates a goog.History object used in an iframe. Loading JS
|
|
code in an iframe is useful for large apps because the JS code can be sent in
|
|
bite-sized script blocks that browsers can evaluate incrementally, as they are
|
|
received over the wire.</p>
|
|
|
|
<p>For an introduction to the goog.History object, see <a
|
|
href="history1.html">history1.html</a> and <a
|
|
href="history2.html">history2.html</a>. This demo uses visible history, like
|
|
the first demo.</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>
