Once the data has loaded, the
external document are available to use in the URLLoader's
code shows:
private function completeHandler(event:Event):void
{
var loader2:URLLoader = URLLoader(event.target);
trace(loader2.data);
}
If the remote document contains name-value pairs, you can parse the data using the
URLVariables class by passing in the contents of the loaded file, as follows:
private function completeHandler(event:Event):void
{
var loader2:URLLoader = URLLoader(event.target);
var variables:URLVariables = new URLVariables(loader2.data);
trace(variables.dayNames);
}
Each name-value pair from the external file is created as a property in the URLVariables
object. Each property within the variables object in the previous code sample is treated as a
string. If the value of the name-value pair is a list of items, you can convert the string into an
array by calling the
String.split()
var dayNameArray:Array = variables.dayNames.split(",");
If you are loading numeric data from external text files, you need to convert the values
into numeric values by using a top-level function, such as
Instead of loading the contents of the remote file as a string and creating a new URLVariables
object, you could instead set the
properties found in the URLLoaderDataFormat class. The three possible values for the
URLLoader.dataFormat
■ URLLoaderDataFormat.BINARY
data stored in a ByteArray object.
URLLoaderDataFormat.TEXT
■
String object.
URLLoaderDataFormat.VARIABLES
■
encoded variables stored in a URLVariables object.
