Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
You could make use of ExternalInterface.addCallback. Therefore the JS function you call with ExternalInterface.call starts some process off then returns straight away. When your process is done it calls your registered flash callback. Therefore you end up with asynchronous. All said and done, why not call the webservice straight from flash?

I'm not calling a JS function from flash until the end of this process. It is the beginning of this process that I want to be made asynchronous. In the beginning I am calling a flash function from JS. That is the piece I am trying to get to be asynchronous. jtgxbass wrote: You could make use of ExternalInterface.addCallback.

Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
setInterval is a handy way to break scope. Have the AS method called by JS set an interval for let's say 10ms, and then have the method assigned to the interval take care of business. Javascript will be free and Flash will keep on going. -Steven Seth Green wrote: I'm not calling a JS function from flash until the end of this process.

Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
Aren't web service calls asynchronous, or am I missing something? I mean,
you typically have to set up a result function to handle the web service
response. Calling the service should not hold the function.
In any case, I'd expect you'd have to handle this like follows:
//javascript
function call(){
swfObject.call();
}
//flash
function call(){
}
function callBack(){
getURL(javascript:callBack();)
}
//javascript
function callBack(){
//this would be called when the service response is recieved.
}

Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
It turns out that the asynchronous web service call actually takes
some extra time (like 100ms) the FIRST time you use that web service
method. Subsequent calls to that method only take 1ms.
So, this first time you call this function from JS, JS is blocked for
about 100ms
//flash
ExternalInterface.addCallback(service_GetEmails, this, getEmails);
function getEmails():Void {
_pendingCall = service.getEmails(emailIds);
_pendingCall.onFault = function(fault){service_onFault(fault);}
_pendingCall.onResult = function(result){toJS(result);}
}
//JS
myMovie.service_GetEmails();
Subsequent calls are super fast. Not sure why this is. Must have
something to do with some overhead incurred during the first call. I'd
be interested to know the answer.
I didn't realize it was only on the first call that so much time was
taken. I can actually live with that. Otheriwse, the setInterval and/or
setTimeout suggestion would have done the trick.
Thanks
