What is the easiest way I can run JavaScript dynamically in a Flex or ActionScript AIR application?
This is what I have so far. It does not work yet and htmlComponent.domWindow is so far null:
if (htmlComponent==null) {
htmlComponent = new HTML();
htmlComponent.htmlText = "<html><script>"+myJavaScript+"</script><body></body></html>";
htmlComponent.addEventListener("complete", function(e:Event):void {trace('html load complete');});
IInvalidating(htmlComponent).validateNow();
}
if (htmlComponent.domWindow && htmlComponent.domWindow.validateXML) {
result = htmlComponent.domWindow.validateXML(value);
}
Your issue, is likely that you do not wait for the loading of the content to actually load. So when your code runs, the DOM is still empty.
var htmlText:String = "<html><script>"+myJavaScript+"</script><body></body></html>";
htmlLoader = new HTMLLoader();
htmlLoader.loadString(htmlText);
// add a complete handler and don't reference the DOM until it's complete
htmlLoader.addEventListener(Event.COMPLETE, loadComplete);
function loadComplete(e:Event):void {
if (htmlLoader.domWindow && htmlLoader.domWindow.myFunction){
//...do what you need to with the domWindow
}
}

I have game server, FMS 4.5 on Windows, already working prefect, and client apps were created in old CS4, and all is perfect.
Now I want to create a mobile app in AS3, and have a problem with remote shared object, which is working perfect in old flash program.
When users are logged into app, I'm receiving an update with onSync method. But whenever remote shared object is updated, I'm not receiving updates.
for example, on client, where I have main_nc as netConnection object:
var ncu_so:SharedObject = SharedObject.getRemote("Zusers", main_nc.uri, false);
ncu_so.addEventListener(SyncEvent.SYNC, syncNCU);
ncu_so.client=this;
ncu_so.connect(main_nc);
private function syncNCU(e:SyncEvent):void {
........
//here I receive new info....
}
and sample on server...
application.onAppStart = function(){
this.Zusers_so = SharedObject.get( "Zusers", false );
...........
}
function sampleUserEnter(client) {
var t=new Object();
t.username=client.username;
application.Zusers_so.setProperty(client.id,t);
//this one call is synced with app
}
function sampleChangeName(client,newName) {
var t=application.Zusers_so.getProperty(client.id);
t.username=newName;
application.Zusers_so.setProperty(client.id,t);
//this IS NOT syncing with app
}
As I said, this code is working with old flash software, but wont update when using AS3. Any idea?
I found an easy solution. Not sure why it works but it works....
var ncu_so:SharedObject = SharedObject.getRemote("Zusers", main_nc.uri, false);
ncu_so.addEventListener(SyncEvent.SYNC, syncNCU);
//I add the listener for checking status
ncu_so.addEventListener(NetStatusEvent.NET_STATUS, statusNCU);
ncu_so.client=this;
ncu_so.connect(main_nc);
private function syncNCU(e:SyncEvent):void {
........
//here I receive new info....
}
//In function for NetStatus event, I just set a simple property
//which I do not use in the app..
//and sunchronization start working as usual after initial sync
private function statusNCU(ev:NetStatusEvent):void {
if (ev.info.code == "NetConnection.Connect.Success") {
ncu_so.setProperty("anyPropertyName",new Date());
}
}
hi i'm trying to use requestAnimationFrame for my game and I actually use this code below, but as you can see ".bind()" create every loop a new function that slow down my game... I'm looking for a "efficient" solution for the best perfomance, thank you in advance :D
function myClass() {
this.loop = function() {
window.requestAnimationFrame(this.loop.bind(this));
/* here myGameLoop */
}
this.loop();
}
above code works but is slow.. instead this "standard" code give me "Type error":
window.requestAnimationFrame(this);
I have also found e tried this Q&A: requestAnimationFrame attached to App object not Window works just ONE time then give the same "Type error" :(
try if you don't believe me: http://jsfiddle.net/ygree/1 :'(
Without knowing the whole story of your object (what else is in there); you could simplify life by just doing this:
function myClass() {
var iHavAccessToThis = 1;
function loop() {
iHavAccessToThis++;
/* here myGameLoop */
requestAnimationFrame(loop);
}
loop();
//if you need a method to start externally use this instead of the above line
this.start = function() { loop() }
//...
return this;
}
Now you don't need to bind anything and you access local scope which is fast.
And then call:
var class1 = new myClass();
class1.start();
Is there a way to print a job without the print dialog box.It will look for the default printer then it will also print all pages.After I click the print button, inside of the movieclip will be print all. Then how can I do it? I don't need AS3 swf not Air if possible..
Here's the code I'm using..
print_btn.addEventListener(MouseEvent.CLICK,printContent);
function printContent(evt:MouseEvent) {
var printJob:PrintJob = new PrintJob();
if (printJob.start()) {
if (content_mc.width>printJob.pageWidth) {
content_mc.width=printJob.pageWidth;
content_mc.scaleY=content_mc.scaleX;
}
printJob.addPage(content_mc);
printJob.send();
}
}
NOTE:
I already used the start2() but this code is for AIR.
It appears there's an answer out there just did some googling:
http://forums.adobe.com/thread/854070
var pj:PrintJob = new PrintJob();
var started:Boolean = pj.start2(null, false);
if(started)
{
pj.addPage(this);
pj.send();
};
pj = null;
I could reduce my problem on a small code snippet. The code creates dynamically an SC player iFrame and displays the ready status. If there is already an iFrame, it removes the old one and creates a new one (runable example on JSFIDDLE):
var player;
var playerId;
var iframe;
var printReady=
function(data)
{
document.getElementById("status").innerHTML = "Ready";
};
function createSoundCloudIframe()
{
document.getElementById("status").innerHTML = "Player not ready";
var contentDiv = document.getElementById("content");
// Remove last Iframe
if(iframe != null){
player.unbind(SC.Widget.Events.READY);
contentDiv.removeChild(iframe);
}
// Create a new Iframe
iframe = document.createElement("IFRAME");
iframe.id = playerId + "ScId";
iframe.src = "http://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F41867062&show_artwork=true";
// Append Iframe
contentDiv.appendChild(iframe);
// Show ready status
player = SC.Widget(playerId + "ScId");
player.bind(SC.Widget.Events.READY, printReady);
playerId ++;
};
The code runs fine when it is executed the first time. But when you try it a second time a nullpointer exception (developer console) will be thrown in this method of api.js:
// Uncaught TypeError: Cannot read property 'parentWindow' of null
function s(a) {
return a.contentWindow || a.contentDocument.parentWindow
}
The method which causes the exeption is SC.Widget(iFrameId);
This problem is in my case not solvable with SC.Widget(iFrameId).load(url, options); function and a hiding of the iFrame:
I wrote a google-web-toolkit wrapper for the SC widget api and use this wrapper with other gwt mediaplayer wrappers in a much bigger project. In this project the exception is thrown repeatedly with a delay of milliseconds which slows down everything. The codesnippet above is only a pure javascript reduction of the problem.
I really need a workaround which removes and clean up all dead references in the api.js when the iFrame is removed! I'm looking for such a workaround for month.
I'm using swf object to embed a swf. I'm trying to user external interface to to call a flash function from JS, but having trouble. I've searched all the docs, read a ton of stuff, and I'm convinced I'm doing it right. Can anyone point out where the problem might be?
var flashvars = {};
var params = {wmode:"opaque", allowscriptaccess:"always" };
var attributes = {id:"MySwf", name:"MySwf"};
swfobject.embedSWF("MySwf.swf", "flashContent", "600", "400", "9.0.0", "swfs/expressInstall.swf", flashvars, params, attributes,function(e){
if(e.success){
_flashRef = e.ref;
testExternalInterface();
}else{
alert("We are sorry, flash is required to view this content.");
}
});
function testExternalInterface(){
var swf = document.getElementById("MySwf");
swf.sendMeTheGoods("TEST TEST");
};
Above is the embed code and js function in my flash I have
if (ExternalInterface.available)
{
trace("adding external interface");
ExternalInterface.addCallback("sendMeTheGoods", sendMeTheGoods);
}
public function sendMeTheGoods(text:String):void
{
trace("setting vars")
trace(text);
txtYouSent.text = text;
}
I'm getting the error Uncaught TypeError: Object # has no method 'sendMeTheGoods'
I've tried both referenceing document.getElementById("MySwf"); and document.getElementById("flashContent"); and I get the error both ways. Any suggestions?
the external interface API is not immediately available, it takes a second for it to be ready. your callback is likely happening before Flash Player has initialized the EI API. try adding a delay in the callback, delaying the invocation of your 'test' function.
var swf = navigator.appName.indexOf("Microsoft") != -1 ? window["MySwf"] : document["MySwf"];
