By the end of this page you will be able to:

  • Use URLRequest and navigateToURL to load swf files into a browser window.


Using a combination of the ActionScript3 URLRequest class and navigateToURL allows new content to be opened within a browser window. Content needs to be contained within the same domain to work, unless permission is granted via policy files. This is a security measure to prevent cross site scripting attacks, but for general purposes within a single domain, policy files and permissions will not be needed and URLRequest and navigateToURL work well to navigate between individual swf files that make up a flash based website.

Creating the Connections

This small tutorial assumes you have a series of swf files that you need to load via button clicks, into a web browser window. On each FLA file, that has the button that will be responsible for the navigation, you need to add a small piece of ActionScript3, on frame one of the Actions Layer.

buttonOne.addEventListener(MouseEvent.CLICK, launchOne);
function launchOne(event:MouseEvent):void {
var swfOne:URLRequest=new URLRequest("swfOne.swf");
navigateToURL(swfOne, "_self");

Easy! This will replace the current browser window content with that of the swfOne.swf. Add as many eventListeners to as many buttons your need to complete your navigation.
