Oh, dear, I'm very sorry, I was talking rubbish!
'href' in this contect is a method of the toc object created in the preceeding code and passed as an argument into the YAHOO.util.Connect.asyncRequest() as part of the callback definition.
toc instproc href {book_mode name} {
my instvar package_id __including_page
if {$book_mode} {
set href [$package_id url]#[toc anchor $name]
} else {
set href [$package_id pretty_link -parent_id [$__including_page parent_id] $name]
}
return $href
}
Clearly it returns a suitable url based on the node in the toc treeview that has been clicked. This url is then used to obtain the page content. It appears that the url is a standard one and I can see no customisation server-side to support the AJAX request.
The responseText property of the response object contains the server's reply which is then inserted into the appropriate page fragment using the innerHTML property.
