Hi,
I am trying to implement a continuous _changes connection to couchdb (cloudant)
with jQuery from a different domain (that's why I am using JSONP).
With:
$.ajax({
url:
"http://app264565.heroku.cloudant.com/geocha/_changes?filter=channel/messages_for&include_docs=true&feed=continuous&channel="+geocha.channelId,
dataType: "jsonp",
jsonp: "geocha.chat.stateChanged"
});
where "geocha.chat.stateChanged" is my callback function, I would expect to get
invoked each time the continuous connection gets a new object.
But it does not.
It connects correctly to the correct couchdb server and I can inspect the
correct returned json (even when I am saving new documents), but I am not able
to invoke any function for changes.
I tried to append an onreadystatechange event listener:
var connection = $.ajax({
url:
"http://app264565.heroku.cloudant.com/geocha/_changes?filter=channel/messages_for&include_docs=true&feed=continuous&channel="+geocha.channelId,
dataType: "jsonp",
jsonp: "geocha.chat.stateChanged"
});
connection.onreadystatechange = geocha.chat.stateChanged;
But as a JSONP-Connection is not a real XMLHttpRequest object that is not
possible.
Does anyone know what is wrong with my code?
I tried heaps of different things ($.get, $.getJSON, $.jsonp plugin). But it is
always the same problem.
I just need a way to invoke a function for each new arriving json.
Thanks
Tom
