// The initially selected tab will be chosen in the following order:
//
// URL fragment identifier (it will be there if the user previously
// bookmarked the application in a specific state)
//
// or
//
// "tab0" (default)
var bookmarkedTabViewState = YAHOO.util.History.getBookmarkedState( "tabview" );
var initialTabViewState = bookmarkedTabViewState || "tab0";

// take place before calling YAHOO.util.History.initialize.
YAHOO.util.History.register( "tabview", initialTabViewState, function( state ) {
// This is called after calling YAHOO.util.History.navigate, or after the user
// has trigerred the back/forward button. We cannot discrminate between
// these two situations.
// "state" can be "tab0", "tab1" or "tab2".
// Select the right tab:
tabView.set( "activeIndex", state.substr(3) );
} );
// Subscribe to this event before calling YAHOO.util.History.initialize,
// or it may never get fired! Note that this is guaranteed to be fired
// after the window's onload event.

// Instantiate the TabView widget
tabView = new YAHOO.widget.TabView( "demo" );
tabView.addListener( "activeTabChange", handleTabViewActiveTabChange );
// This is the tricky part... The onLoad event is fired when the user
// comes back to the page using the back button. In this case, the
// actual tab that needs to be selected corresponds to the last tab
// selected before leaving the page, and not the initially selected tab.
// This can be retrieved using getCurrentState:
var currentState = YAHOO.util.History.getCurrentState( "tabview" );
tabView.set( "activeIndex", currentState.substr(3) );
} );
function handleTabViewActiveTabChange( e ) {
var currentState = YAHOO.util.History.getCurrentState( "tabview" );
var newState = "tab" + this.getTabIndex( e.newValue );
// The following test is crucial. Otherwise, we end up circling forever.
// Indeed, YAHOO.util.History.navigate will call the module onStateChange callback,
// which will call tabView.set, which will call this handler and it keeps
// going from here...
if ( newState != currentState )
YAHOO.util.History.navigate( "tabview", newState );
}
// The call to YAHOO.util.History.initialize should ALWAYS be from within
// a script block located RIGHT AFTER the body tag (this seems to prevent
// an edge case bug on IE - IE seems to sometimes forget the history when
// coming back to a page, and the back - or forward button depending on the
// situation - is disabled...)
YAHOO.util.History.initialize();
