//):
// ignore XML white space
XML.prototype.ignoreWhite = true;
// Construct an XML object to hold the server's reply
var loginReplyXML:XML = new XML();
// this function triggers when an XML packet is received from the server.
loginReplyXML.onLoad = function(success:Boolean) {
if (success) {
// (optional) Create two text fields for status/debugging
// status_txt.text = this.firstChild.attributes.status;
// debug_txt.text = this.firstChild;
switch (this.firstChild.attributes.STATUS) {
case 'OK' :
_global.session = this.firstChild.attributes.SESSION;
trace(_global.session);
gotoAndStop("welcome");
break;
case 'FAILURE' :
gotoAndStop("loginfailure");
break;
default :
// this should never happen
trace("Unexpected value received for STATUS.");
}
} else {
trace("an error occurred.");
}
};
// this function triggers when the login_btn is clicked
login_btn.onRelease = function() {
var loginXML:XML = new XML();
// create XML formatted data to send to the server
var loginElement:XMLNode = loginXML.createElement("login");
loginElement.attributes.username = username_txt.text;
loginElement.attributes.password = password_txt.text;
loginXML.appendChild(loginElement);
// send the XML formatted data to the server
