Using XMLHttpRequests

[Alexander Orlov]

I believe XMLHttpRequest is part of the HTML5 standard? Is there a way
to make XMLHttpRequests like in JavaScript?

Yes, both the classic DOM library ('dart:dom') and our newer API ('dart:html') support it. It's a little rough right now, but you can see an example of using it in Swarm: https://code.google.com/p/dart/source/browse/branches/bleeding_edge/dart/client/samples/swarm/DataSource.dart#224.

The code from the link shows a request with async = false:
final req = new XMLHttpRequest();
req.open('GET', '${Sections.home}/data/$name', false);
req.send();
_htmlBody = req.responseText;

Is there an example with async = true?

This post: http://dartwatch.com/index.php/2011/11/exploring-dart-client-server-written-in-dart/
has an example using XMLHttpRequest,

you just need to change the line in client.dart
req.open("POST",url,false);
to
req.open("POST",url,true);

and the event handler will run async.

The code is also in github here: https://github.com/chrisbu/dartwatch-client-server-example

Chris.
