In-Depth Information
Let's go with the latter and bind to the
"u"
key being released by binding to the
keyup
event.
When it is, we'll create a fake
data
object containing all the information required to create a
new comment and pass it to the
displayComment
function. That comment will then be
displayed in the UI.
Hit the
"u"
key a few times and see the comments appear.

){
displayComment
({
"id"
:
"comment_1"
,
"comment_post_ID"
:
1
,
"date"
:
"Tue, 21 Feb 2012 18:33:03 +0000"
,
"comment"
:
"The realtime Web rocks!"
,
"comment_author"
:
"Phil Leggetter"
});
}
});
});
Great! We now know that our
displayComment
function works exactly as we expect it to.
Remember to remove the test function
before you go live or you'll really confuse your user
every time they press
"u"
.
