Hi Justin,
you are right, the host, port, etc. are not needed and there should be
simply '/listen'. It works however even when I call Ajax with port --
the page itself just must be loaded at the same host, same port
(http://localhost:4567 in my case -- the default Sinatra [http://
sinatra.rubyforge.org] port).
BUT, the bigger problem is, that Ajax.PeriodicalUpdater keeps
inserting *more* elements than it receives from the server. I have
this code:
new Ajax.PeriodicalUpdater('chat_message', '/listen',
{ asynchronous:true,
frequency: 3,
method: 'get',
insertion: Insertion.Bottom }
);
This inserts four, five, fifteen elements in the <div id="chat"></
div>. Which effectively hinders *updating* the div content. After
frustratingly long time I rolled some periodical updater myself:
var Application = {
run : function() {
this.updater = new Ajax.Updater('chat_message', '/listen',
{ asynchronous:true,
method: 'get',
insertion: Insertion.Bottom }
);
},
start: function() {
this.interval = setInterval('Application.run()', 2000);
},
stop : function() {
clearInterval(this.interval);
this.updater = null;
},
}
Which *correctly* inserts only the elements returned fromm the
server... So I consider my problem solved, albeit not in an desired
way.
I don't know if this is some failure or misunderstanding on my part or
something goes weird inside Prototype...
Any ideas?
