externalinterface

问题 I am using the code below to find the User Agent using ActionScript 3: var userAgent:String = ExternalInterface.call("navigator.userAgent.toString"); The code is working in Firefox 13, Google Chrome & Opera, but the User Agent value as null in IE8. Is there any code snippet that will work here or any other way to implement this? 回答1: toString is unnecessary, since userAgent is a string property. Use this syntax instead: var userAgent:String = ExternalInterface.call("function(){return

问题 An idea is to make Win Mobile phone become super alarm for car. Now I am searching for devices simalr to Velleman interface board, but I need device which can be connected to mobile device using bluetooth trough compact framework and C#. I need digital inputs for caching real events such as engine started or door opened.

问题 JavaScript and the Flash Player can exchange data via Flash's ExternalInterface mechanism: you register ActionScript functions that you would like to be able to be called from JavaScript. My question: How can I figure out what ActionScript functions of a Flash object are available for me to call from JavaScript (assuming they are not documented)? Is there a programatic way to do this in JavaScript? Thanks! 回答1: you can't enumerate them directly (they won't be listed in a for..in loop), but

问题 I was wondering how to achieve the native scrollbar effect which TheFWA (thefwa.com) has managed to do pretty well (I am not a fan of Flex scrollbars). I found this post (http://stackoverflow.com/questions/318675/how-can-i-create-a-flex-application-with-dynamic-height), and implemented the technique, as I am calling a JS function through ExternalInterface every time, when the flash object changes size. This JS function simply resizes the div which holds the flash object, which creates the

问题 Hey, so I'm having a bunch of trouble getting ExternalInterface to work, which is odd, because I use it somewhat often. I'm hoping it's something I just missed because I've been looking at it too long. The flash_ready function is correctly returning the objectID, and as far as I can tell, everything else is in order. Unfortunately, when I run it, I get an error (varying by browser) telling me that basically document.getElementById( <movename> ).test() is not a valid method. Here's the code:

问题 HI, im trying to call a javascript function from my actionscript code but its not working; as3: if (ExternalInterface.available) { try { ExternalInterface.addCallback("changeDocumentTitle",null); } catch(error:Error) js (inside velocity file using swfobject) function changeDocumentTitle() { alert('call from SWF'); } anyone know what could be happenin? 回答1: If you are trying to invoke a JS function from within your Flex app, you want to use ExternalInterface.call(...) and not ExternalInterface

问题 I have a small flash app that I load dynamically upon jQuery document.ready. It works in all browsers except for IE. When the installed version of FlashPlayer is less than 10.1, the callbacks added via addCallBack are not present. I've compiled the app with the mxmlc in flex 3.5 which the target player is 9.0.124 so it should work. I've built other larger flex apps and had no problems with ExternalInterface and IE. The app loads and the ExternalInterface.call method fires and IE responds, but

问题 i apologize if my terminology is off, my actionscript skills are pretty weak sauce. so, i have some actionscript that makes a ExternalInterface.call('someFunction'); call. is it possible to reference the html object that made the call to someFunction directly using the ExternalInterface.call call? Assume that the object that makes the call also has some Callbacks (via ExternalInterface.addCallback) that are accessible via javascript. Currently: Actionscript source ExternalInterface.call(

问题 Summary I want to be able to call a JavaScript function from a Flex app using ExternalInterface and pass a reference to a different JavaScript function as an argument. Base Example Given the following JavaScript: function foo(callback) { // ... do some stuff callback(); } function bar() { // do some stuff that should happen after a call to foo } I want to call foo from my flex app using ExternalInterface and pass a reference to bar as the callback. Why Really, foo is not my function (but,

问题 Boy-oh-boy do I hate external interface. I have a video player that utilizes external interface to control the flash object and to allow the flash object to pass messages to the same javascript. For a time it worked well in all browsers. Then a few days ago i went to go test it in all browsers before i moved the project out of development, and found that the application broke in internet explorer 9. The following error appeared in the console: SCRIPT16389: Could not complete the operation due
