I have a variable
var qstAccessCode:String = "default";
and a loader with URLRequest
var qst:XML;
var qstLoader:URLLoader = new URLLoader();
qstLoader.load(new URLRequest("http://dl.dropbox.com/u/44181313/Qaaps/Audio/" + qstAccessCode + ".qst"));
qstLoader.addEventListener(Event.COMPLETE, processQST);
function processQST(e:Event):void {
qst = new XML(e.target.data);
trace("QST loading");
}
I would like to use the value of qstAccessCode to complete the URL (so I can change the URL based on user input - if no input then use "default") but I get an error:
"1120: Access of undefined property qstAccessCode"
Is this to do with scoping? How can I complete the URL? Thanks in advance.
Edit: I haven't been able to get clear on this, so I'm also going to look at generating the complete URL from the user-input function and see if I get the URLRequest to pick it up as a variable. If there are any further comments on the original idea I will be very grateful to read them. Cheers.
Edit: #Moorthy I have qstAccessCode defined like this:
var qatAccessCode:String = "default";
var stageText:StageText = new StageText();
stageText.returnKeyLabel = ReturnKeyLabel.GO;
stageText.stage = this.stage;
stageText.viewPort = new Rectangle(225, 765, 200, 35 );
stageText.addEventListener(Event.CHANGE, onChange);
function onChange(e:Event):void
{
qatAccessCode = stageText.text;
trace(qatAccessCode);
}
It traces keyboard entry when I test movie (Air 3.2 for Android).
qstAccessCode should be defined in the same scope as the URLRequest.
You must defined property qstAccessCode like:
var qstAccessCode:string;
qstAccessCode's value is your url address.

I would like to change the pitch of a sound file using the HTML 5 Audio node.
I had a suggestion to use the setVelocity property and I have found this is a function of the Panner Node
I have the following code in which I have tried changing the call parameters, but with no discernible result.
Does anyone have any ideas, please?
I have the folowing code:
var gAudioContext = new AudioContext()
var gAudioBuffer;
var playAudioFile = function (gAudioBuffer) {
var panner = gAudioContext.createPanner();
gAudioContext.listener.dopplerFactor = 1000
source.connect(panner);
panner.setVelocity(0,2000,0);
panner.connect(gainNode);
gainNode.connect(gAudioContext.destination);
gainNode.gain.value = 0.5
source.start(0); // Play sound
};
var loadAudioFile = (function (url) {
var request = new XMLHttpRequest();
request.open('get', 'Sounds/English.wav', true);
request.responseType = 'arraybuffer';
request.onload = function () {
gAudioContext.decodeAudioData(request.response,
function(incomingBuffer) {
playAudioFile(incomingBuffer);
}
);
};
request.send();
}());
I'm trying to achieve something similar and I also failed at using PannerNode.setVelocity().
One working technique I found is by using the following package (example included in the README): https://www.npmjs.com/package/soundbank-pitch-shift
It is also possible with a biquad filter, available natively. See an example here: http://codepen.io/qur2/pen/emVQwW
I didn't find a simple sound to make it obvious (CORS restriction with ajax loading).
You can read more at http://chimera.labs.oreilly.com/books/1234000001552/ch04.html and https://developer.mozilla.org/en-US/docs/Web/API/BiquadFilterNode.
Hope this helps!
When the user try to download the file ,i need to open a new html window and download the file , currently iam using "ExternalInterface.call" but i need to set the "requestmethod" otherwise server is throwing the error ,how to specify "requestmethod"?
Why not use the global navigateToURL method? You can pass in a URLRequest object which has a property called method and will solve your problem.
So you need something like this:
var request:URLRequest = new URLRequest("http://example.com");
request.method = URLRequestMethod.POST; // or anything you want
// parameters can be added to a URLVariables object
// which then can be set as requests data property
// example:
var params:URLVariables = new URLVariables();
params.username = "test";
params.password = "123";
request.data = params;
// load the page
// specify '_blank' parameter to open it in a new browser window
navigateToURL(request, "_blank");
When I execute the following code:
var urlRequest:URLRequest = new URLRequest("http://somehost/with/some/path?andsomequerystring=true");
urlRequest.method = 'POST';
var urlLoader:URLLoader = new URLLoader(urlRequest);
urlLoader.addEventListener(Event.COMPLETE, function(event:Event):void{
trace('sweet');
});
It turns my explicit POST request to GET due to the presence of the querystring. If I remove the querystring (and serialize as part of the POST body), it successfully makes the corresponding POST request. Is there any way to prevent it from doing that? My server requires that a POST request be made with a querystring.
Ah think I found the answer, seems you have to specify a body as well or else it will still send as a GET request from their docs:
Note: If running in Flash Player and the referenced form has no body,
Flash Player automatically uses a GET operation, even if the method is
set to URLRequestMethod.POST. For this reason, it is recommended to
always include a "dummy" body to ensure that the correct method is
used.

It is because the way you are having your url. If you want to have your variables for POST method you need to use URLVariables.
var urlRequest:URLRequest = new URLRequest(YOUR_REQUEST_URL_HERE);
var variables:URLVariables = new URLVariables();
variables.andsomequerystring = true;
urlRequest.data = variables;
urlRequest.method = 'POST';
var urlLoader:URLLoader = new URLLoader(urlRequest);
urlLoader.addEventListener(Event.COMPLETE, function(event:Event):void{
trace('sweet');
});
Instead of many if conditionals, I want to call a constructor according to a string value
var valueString:String = "myNewClassB";
var value:Class = valueString as Class;
new value() // new value() == new myNewClassB()
I know it's gonna fail, I need help. Thanks.
var ClassReference:Class = getDefinitionByName("myNewClassB");
var instance = new ClassReference();
That's the basics, bud.
If you want to do that, there are two ways, either assign classes to a list of classes made for an example in a object:
var list:Object = {
classA: FirstClass,
classB: SecondClass,
classC: ThirdClass
}
and than call them by a string:
var desiredObject:* = new (list["classA"] as Class)();
or you could also use getDefinitionBtName but than if you want to get a class you need to provide a full name (with the package)
var desiredClass = getDefinitionByName( "com.somedomain.SomeClass" );
If you are laoding an SWF content and than want to get a class from it you should use that loader loaderInfo.applicationDomain.getDefinition( "....class" );
you can also check if a class is defined by:
loaderInfo.applicationDomain.hasDefinition( "....class" );
link: ApplicationDomain.getDefinition
link: ApplicationDomain.hasDefinition
link: LoaderInfo
In the following example (yes, I am coding on my timeline while I try to work this out - I know, I know) I am loading an SWF in an HTML page and then directing the SWF to get the query parameters from the current URL. The query parameter will contain the source for the video to play.
This seems straight forward to me but I cannot get myURL = urlVars.videoloc; to work. More specifically, urlVars.videoloc seems to be undefined rather than holding the query parameter from the URL. All other variables are correct; both wholeURL and urlVars are defined.
//Initialize Global Event Listener
player.addEventListener(Event.ADDED_TO_STAGE, getPlay, false, 0, true);
//Function to play the video
function getPlay(e:Event):void {
var wholeURL:String = ExternalInterface.call("window.location.search.toString");
var urlVars:URLVariables = new URLVariables(wholeURL);
var myURL:String = urlVars.videoloc; //<--- Trouble, returning 'undefined'
errorBox.text = "videoloc="+urlVars.videoloc+"\nwholeURL="+wholeURL+"\nurlVars="+urlVars+"\nmyURL="+myURL; //<--- The reason I know it is returning 'undefined'
if (myURL) {
player.load(myURL);
player.play();
}
}
Ideally you should use a debugger to inspect the makeup of your URLVariables object.
If you're unable to do things the easy way, you could do this to trace its contents:
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
As you can see, you can step through every parameter inside urlVars using a for in loop.
I'm guessing videoLoc is your first parameter? Look at the results of this test of mine:
var address:String = "http://www.google.ca/search?q=test&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a";
var urlVars:URLVariables = new URLVariables(address);
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
The output of this is:
aq=t
rls=org.mozilla:en-GB:official
client=firefox-a
http://www.google.ca/search?q=test
ie=utf-8
oe=utf-8
See what happened to the q parameter? To fix this, use only the text past the ?
var address:String = "http://www.google.ca/search?q=test&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a";
var urlVars:URLVariables
= new URLVariables(address.substr(address.indexOf('?')+1));
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
