Pending
Requests
On
some websites, the onDocumentComplete event is fired to signify
that the site has finished loading, but due to Javascript functions
or Ajax, extra content is loaded on the page afterwards. The pending
request functionality is a way of knowing when this content
is rendered that has been generated after the page has loaded.
The
NetworkEvent class has the new method, hasPendingRequests which
can be called from inside onDocumentComplete. This will return true
if the page still has network requests that are yet to complete.
The
NetworkListener class has the method, onDocumentPendingRequestsComplete.
This works in the same way that the onDocumentComplete function
works, but will fire only when extra content has finished loading
if there is any.
The code segment below shows how this is
implemented.
See PendingRequests.java in the examples folder
for a working demonstration.
IMozillaBrowserCanvas browser;
...
browser.addNetworkListener(
new NetworkAdapter() {
public
void onDocumentComplete( NetworkEvent e ) {
//
The page has finished loading but extra content could still be loaded.
if
( e.hasPendingRequests() ) {
//
There is still content to load.
}
}
public
void onDocumentPendingRequestsComplete( NetworkEvent e ) {
//
All content on the page has now been loaded.
}
}
