Hi all,
How to reRender the page via js in Chat demo of the lift ?
Here is an example:
### In the index page, show all the message that the users sent
user 1: message 1
user 2: message 2
user 3: message 3
user 4: message 4
user 5: message 5
###
Here are 5 messages, then i want to refresh the messages when the
message count >5,
###
user 1: message 1
user 2: message 2
user 3: message 3
user 4: message 4
user 5: message 5
refresh: can't refresh, also show 6 messages, i want to show 5
messages.
###
Here is code in the Comet:
###
lass Chat extends CometActor with CometListener {
...
override def lowPriority = {
case ChatServerUpdate(value) =>
val update = (value -- chats).reverse.map(b => AppendHtml
(infoId, line(b)))
partialUpdate(update)
chats = value.take(5)
}
...
}
###
In the example, when the message counts >=5, i set the count to 5
via
###
chats = value.take(5)
###
Is there a js function can do this, when the chats's size is bigger
than 5, then refresh the messages.
Thanks for any suggestion!
Cheers,
Neil
