Hi,
Before I answer your query, I would recommend you to use HTTPService or
XML to load xml files. It would save you from lot of coding for doing
simple things :)
Ok coming to your query. There are two things:
1) You are showing alert just after calling load(..). Chances are that
data has not yet loaded and that's why onLoad is not yet called and
newXML has not got set.
2) What you are thinking, is known thing(scope issue). You can be sure
of scoping by using mx.utils.Delegate class to create callback function
for onLoad.
See the modified code below:
function search()
{
var newXML;
var myXML = new XML();
myXML.ignoreWhite = true;
myXML.load("http://myserver.com/test.xml";);
myXML.onLoad = mx.utils.Delegate.create(this, processXML);
alert("Application::search()-> " + newXML)
}
function processXML(success:Boolean)
{
if(success){
newXML = "new value";
}else{
}
alert("Application::processXML()-> " + newXML);
}
I have done another change. I have placed newXML in processXML(..)
function also, I guess, you mean to pop-up an alert when xml is loaded
and parsed.

Subject: [flexcoders] Scoping issue in event handler ?
Hi,
I am trying to set an external variable within an onLoad() event
handler and later trying to access it as below .
The variable in question here is newXML . After setting it
within the eventHandler, trying to access it outside the eventHandler
thru the alert statement on the last line brings up an empty pop-up. My
guess is that this is a scoping issue...however I do not seem to be able
to set the variable newXML (and later retrieve its value) the way I am
trying to.
Would appreciate any help with this .
function search(){
var newXML;
var myXML = new XML();
myXML.ignoreWhite = true;
myXML.load("http://myserver.com/test.xml";);
myXML.onLoad = function(success:Boolean){
if(success){
newXML = "new value";
}else{
}
}
alert(newXML);
}
Thanks
-Daman
