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() method, as follows:
var dayNameArray:Array = variables.dayNames.split(",");
If you are loading numeric data from external text files, convert the values into numeric values by using a top-level
function, such as int(), uint(), or Number().
Instead of loading the contents of the remote file as a string and creating a new URLVariables object, you could instead
set the URLLoader.dataFormat property to one of the static properties found in the URLLoaderDataFormat class.
The three possible values for the URLLoader.dataFormat property are as follows:
URLLoaderDataFormat.BINARY—The URLLoader.data property will contain binary data stored in a ByteArray
object.
URLLoaderDataFormat.TEXT—The URLLoader.data property will contain text in a String object.
URLLoaderDataFormat.VARIABLES—The URLLoader.data property will contain URL-encoded variables stored
in a URLVariables object.
The following code demonstrates how setting the URLLoader.dataFormat property to
URLLoaderDataFormat.VARIABLES allows you to automatically parse loaded data into a URLVariables object:
