Reading and displaying RSS feeds in Flash MX - Finished! 2004-03-12 - By Merrill, Jason
Back
Congrats Bryan! Job well done.
I noticed one thing in your .fla though:
myXML.onLoad = function (success){
if (success) {
//create Flash object from the XML
//the function "toObject()" is located in the .as file
o = this.toObject ();
}
Display();
}
You have Display() outside the if(success){} logic. It works because the XML
loads successfully every time, but I would put it inside - otherwise if the XML
fails to load, you also aren't trying to display the data. I would change it
like this:
myXML.onLoad = function (success){
if (success) {
//create Flash object from the XML
//the function "toObject()" is located in the .as file
o = this.toObject ();
Display();
}
}
You could also throw up an error if the XML fails, like this:
myXML.onLoad = function (success){
if (success) {
//create Flash object from the XML
//the function "toObject()" is located in the .as file
o = this.toObject ();
Display();
} else{
trace('error: XML failed to load');
}
}
