Hi everybody,
Still working on a class that included a check for an online connection
using an online file. Although it works, I feel that the coding could be
far more efficient as now I use two methods to retrieve the value for
one property. On thing is that I am having a hard time to find a way to
return a value from a function that contains a loop in which a property
is set. Hmm; confusing? This is the setup
Private var online;
Public function checkOnlineStatus() // loads (or not) a textfile and
sets the property online; no return value (yet)
Public function pollOnline() // Polls for property online through a
getter and puts result in a textfield.
I would actually like to have one method in which the above two are
combined and that returns a value for the online status (through getter
appISOnline).
And here's the code:
/////////////////// CODE //////////////////////////////
public function checkOnlineStatus():Void {
var self:CDapplication = this;
self.online = undefined;
var onlineCheck_lv:LoadVars = new LoadVars();
onlineCheck_lv.onLoad = function(success) {
self.online = success;
delete this;
};
onlineCheck_lv.load(onlineURL + "?nocacheVar=" +
Math.random());
}
public function pollOnline(displayArea:TextField):Void {
var poll;
var self:CDapplication = this;
poll = setInterval(function () {
if (self.appIsOnline) {
self.showData(self.appIsOnline,
displayArea);
clearInterval(poll);
}
}, 1000);
}
///////////// END CODE /////////////////////////////////
Thanks for any input.
John
