8 <h1>Interoperability of digilib HTML pages with the Alcatraz toolbar</h1>
|
|
|
9
|
|
|
10 <p>A toolbar-friendly digilib page must define a Javascript variable
|
|
|
11 <b><code>toolbarEnabledURL</code></b> whose value is a HTTP URL that
|
|
|
12 produces a <em>toolbar-enabled</em> page. The toolbar should present a
|
|
|
13 button to "take over" the page design by replacing
|
|
|
14 the current page with the page from the given URL.</p>
