Howdy folks,
Just trying to get my head wrapped around this issue. In
photo_navigation.as, I'm trying to get back a return type of XML from
xml_loader. But when I attempt this: "trace("my_xml = " + my_xml);", I end
up getting: "my_xml = undefined". Somewhere along the line I'm losing the
my_xml value in xml_loader.as because the value returned is empty.
I've been banging my head against this problem awhile now and need a second
or third opinion...
// Contents of xml_loader.as:
class xml_loader extends MovieClip {
// constructor
public function xml_loader() {
}
// public method to load the xml file
public function load_xml(xml_file:String) {
var myclass = this
// Create a local variable that points back to the current object
var thisObj:xml_loader = this;
// Create a local variable, which is used to load the XML file.
var my_xml:XML = new XML();
// Ignore whitespace
my_xml.ignoreWhite = true;
// Upon successful load of the xml file
my_xml.onLoad = function(success:Boolean) {
if (success) {
thisObj.init(my_xml);
// return the my_xml variable value
return my_xml;
} else {
trace("error loading XML");
return null;
}
};
// Begin loading the XML document.
my_xml.load(xml_file);
}
public function init(my_xml):Void {
// uncommenting the following line results in the xml being printed
correctly
// trace(my_xml);
}
}
// Contents of photo_navigation.as
class photo_navigation extends xml_loader {
// constructor
public function photo_navigation(xml_file:String) {
// take the xml_file string and pass it to the superclass
"xml_loader"
var my_xml = load_xml(xml_file);
// trace out the contents of "my_xml"
trace("my_xml = " + my_xml);
}
}
// Contents of photos.xml
