Parsing url parameters in a String - actionscript-3

I am using the example code in flash. I want a single variable and not the whole text.
I have a dynamic textfield called OUTPUT on the stage.
var fl_TextLoader:URLLoader = new URLLoader();
var fl_TextURLRequest:URLRequest = new URLRequest("http://www.testing.com/Christmas.txt");
fl_TextLoader.addEventListener(Event.COMPLETE, fl_CompleteHandler);
function fl_CompleteHandler(event:Event):void
{
var textData:String = new String(fl_TextLoader.data);
OUTPUT.text = textData;
}
fl_TextLoader.load(fl_TextURLRequest);
The Christmas text file contents:
Var1=Jesus&Var2=Mary&Var3=Christmas
The OUTPUT comes out with the whole string. How do I get the url parameter values separately?
Like OUTPUT.text = textData.Var1; (<--- But this does not work.)


The .data property is just a string, the raw data returned by the HTTP call, so you will have to parse the variable-value pairs, either using simple .split() on the strings or using the URLVariables object, that can do the parsing for you:

Variable name is an integer in ActionScript 3

I am pulling .json info from weatherunderground into Flash CC. After I parse the data I am left with the following variables:
I am trying to get to the "conditions" variable. But I can't get there because of the integer/number "0" How do I format it?
This is my code:
function completeHandler(event: Event): void
{
var loader1: URLLoader = URLLoader(event.target);
var data1: Object = JSON.parse(loader1.data);
trace(data1.forecast.simpleforecast.forecastday.0.conditions);
}
This works for variables that don't have an integer in their path.

forecastday is an array, which you can see in the Value column ([] (#...). The JSON is just telling you what is contained in each element of the array, so just use data1.forecast.simpleforecast.forecastday[0].conditions, or loop through for each day.

JSON String parsing each character as an object

I have a JSON file that contains what I believe to be a correct JSON string:
{"title": "exampleTitle", "tipTitle": "exampleTipTitle", "tip": "exampleTip"}
I'm trying to parse said file and take out the 3 values then store them in variables, however currently, it parses each individual character as a separate object, therefore:
JSONobj[1] = "
and so on. Assuming that currentLocation = the directory location of the json file.
Code
var jsonLocation = currentLocation + "json.txt";
var request = new XMLHttpRequest();
request.open("GET", jsonLocation, false);
request.send(null);
var returnValue = request.responseText;
var JSONobj = JSON.parse(JSON.stringify(returnValue));
var headerTitle = JSONobj[0];
A few clarifications, the stringify is in because it was throwing an unexpected token error. I've tried changing the file tile to .json instead but that also makes no difference. "It also gives off a XMLHttpRequest on the main thread is deprecated" but I'm not particularly sure how to solve that issue. Any help would be appreciated.

var returnValue = request.responseText;
Here returnValue is a string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
var JSONobj = JSON.parse(JSON.stringify(returnValue));
Here you convert the string of JSON to JSON. So you have a JSON string representing a string, and that string is a representation of a data structure in JSON.
"\"{\\"title\\": \\"exampleTitle\\", \\"tipTitle\\": \\"exampleTipTitle\\", \\"tip\\": \\"exampleTip\\"}"
Then you parse it and convert it back to the original string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
So you end up back where you start.
Just don't use JSON.stringify here, and you'll convert your JSON to a JavaScript object:
var javascript_object = JSON.parse(returnValue);
Then you have an object, but it doesn't have a 0 property so it doesn't make sense to access it with javascript_object[0]. The properties have names, such as javascript_object.title.

Your JSON doesn't describe an array, so indexing into it with an index like 0 doesn't make sense. Your JSON describes an object, which will have properties with the names title, tipTitle, and tip.
Additionally, you're overdoing your parsing: You just want to parse, not stringify (which is the opposite of parsing):
var JSONobj = JSON.parse(returnValue);
So:
var JSONobj = JSON.parse(returnValue);
var headerTitle = JSONobj.title;
console.log(headerTitle); // "exampleTitle"
Side note: By the time you've assigned it to the variable you've called JSONobj, it isn't JSON anymore, it's just a normal JavaScript object, so that name is a bit misleading. If you're writing source code, and you're not dealing with a string, you're not dealing with JSON anymore. :-)

problems reading int from bytearray

This is my first question, so do not judge strictly.
I have an object that I'm getting from php server to as3(flash) client. That object is AMF encoded, so I write server response to ByteArray:
var ba:ByteArray = new ByteArray();
ba.writeUTFBytes( rawData );
and than I'm reading object from ByteArray:
ba.position = 0;
var response:Object = ba.readObject();
Part of object contains such data:
{
'money' : 900
}
And when reading object from ByteArray, I get a seven-digit number ~ 1824344 instead of 900. But when I get form server String '900' or int value equals 100 - data reads correctly.
Has someone had such a problem?

You have to read the same way you wrote. If you write something using writeUTFBytes(), you have to read it using readUTFBytes().
In this case you should use writeObject() and readObject() because you are writing pure Object but not String.

xml parsing in flex

a simple little question. I have an xml file and im putting this xml file in an XML object
var receivedXML:XML
In some function, I have:
var xmlList:XMLList = new XMLList();
xmlList = receivedXML.some.attributes.here;
object.functionDoStuff = xmlList;
The function functionDoStuff takes xmlList as its argument:
function functionDoStuff(xmlList:XMLList) {}
When does receivedXML get parsed, is it when we assign it to xmlList, or is it when it gets used in the next instruction by the function functionDoStuff?

It isn't parsed at either point. It is parsed when receivedXML was created. After that point it is an 'object' and not XML.

AS3 I need to convert a string from input to an AS3 object

How can I do this? Here's what I have:
function send(input):void{
// input.text = "{key: 'value'}"
var x:* = stringToObject(input.text)
// then be able to do this
var y:* = x.key;
// then y must be equal to 'value'
trace(y) // this is just a string
}

You'll need to include the JSON library to be able to parse JSON strings into objects.
Reference the as3corelib library for more info.
