There are several ways to do this. I usually use javascript in the html wrapper to split the url params in to an array:
var _sPassedUrlParms = new String(document.location).split('?')[1]; //Get any passed-in querystring parms then, I pass that into the Flex app using flashvars: AC_FL_RunContent( "src", "${swf}", . "flashvars", _sPassedUrlParms, . Then I access those flashvar values in Flex using application.application.parameters object, which will have a property:value for each passed in url param. You can also use ExternalInterface to get the URL information instead of using the javascript, google for examples of that. I found this component that seems to encapsulate that functionality: http://www.flexpasta.com/index.php/2008/03/15/getting-url-parameters-host-na me-port-in-flex-actionscript/ Tracy Spratt, Lariat Services, development services available _____ From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Penny Laus Sent: Saturday, January 23, 2010 10:41 PM To: flexcoders@yahoogroups.com Subject: [SPAM] [flexcoders] Reading URL arguments from within initApp() I'm working on a registration system that will be used by new and existing participants. The customer would like to be able to email existing participants a URL that bypasses the login screen. So, if the usual URL is http://www.foo. <http://www.foo.com/register.html> com/register.html They would like to use a URL that skips the landing screen and goes right to the registration details (name, address, etc.): http://www.foo. <http://www.foo.com/register.html?user=bob&password=pluto> com/register.html?user=bob&password=pluto (Those aren't the exact arguments but should illustrate the point.) I've been hunting around but haven't sorted out where to find the correct properties. If I can read in the URL, I can pass the data to my existing login function and carry on from there. If there's a more standard/best-practice way of starting the app with URL arguments, I'm all ears. Would someone be so kind as to point me in the right direction? Chances are, I just haven't figured out the right name for the feature I'm after. Thanks!!!
