Constructor Detail
URLVariables()Constructor
public function URLVariables(source:String = null)

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Creates a new URLVariables object. You pass URLVariables objects to the data property of URLRequest objects.

If you call the URLVariables constructor with a string, the decode() method is automatically called to convert the string to properties of the URLVariables object.

Parameters
source:String (default = null) — A URL-encoded string containing name/value pairs.
Method Detail
decode()method
public function decode(source:String):void

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Converts the variable string to properties of the specified URLVariables object.

This method is used internally by the URLVariables events. Most users do not need to call this method directly.

Parameters

source:String — A URL-encoded query string containing name/value pairs.


Throws
Error — The source parameter must be a URL-encoded query string containing name/value pairs.
toString()method 
public function toString():String

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Returns a string containing all enumerable variables, in the MIME content encoding application/x-www-form-urlencoded.

Returns
String — A URL-encoded string containing name/value pairs.
Examples How to use this example
URLVariablesExample.as

The following example opens the remote application hosted at http://www.[yourDomain].com/application.jsp in a new browser window and passes data about a user session, captured in a URLVariables object, to the application.

Highlights of the example follow:

  1. The constructor function creates a URLRequest instance named request, taking the URL of the remote application as a parameter.
  2. A URLVariables object is created and two of its properties are assigned values.
  3. The URLVariables object is assigned to the data property of the URLRequest object.
  4. The example calls navigateToURL, which opens a new browser window to the remote application's URL.

Note: To run the example, the remote application URL in the example must be replaced with a working URL. Additionally, you would need server code to process the information captured by Flash Player in the URLVariables object.

package {
    import flash.display.Sprite;
    import flash.net.navigateToURL;
    import flash.net.URLRequest;
    import flash.net.URLVariables;

    public class URLVariablesExample extends Sprite {

        public function URLVariablesExample() {
            var url:String = "http://www.[yourDomain].com/application.jsp";
            var request:URLRequest = new URLRequest(url);
            var variables:URLVariables = new URLVariables();
            variables.exampleSessionId = new Date().getTime();
            variables.exampleUserLabel = "guest";
            request.data = variables;
            navigateToURL(request);
        }
    }
}
