问题 Since URLLoader is async, how to make sure the order of data from server side is the same as the loader.load() call? In other words, the data order in totalResults is the same order of url-related content? Following is code snippet: 1.for each(var url in urls) { loadData(url); } 2.private function loadData(url:String):void { var urlLoader:URLLoader = new URLLoader(); urlLoader.addEventListener(Event.COMPLETE, completeHandler); var request:URLRequest = new URLRequest(url); urlLoader.load

问题 In ActionScript (AS3) how do I find all the classes that implement a particular interface? 回答1: In OOP terms, you never want to be able to do this: the primary characteristic of interfaces is they are terms of a contract. Any class can choose to fulfill that contract and be able to say "I implement this interface". Any code that references an instance of the interface don't care what class actually implements it: they don't have to; that's the really cool part of interfaces. But if you want

问题 In Flash Builder, if I new a Flex Mobile Project, and paste the following code: <?xml version="1.0"?> <!-- Simple example to demonstrate the Halo Canvas layout container. --> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"> <s:Group/> <mx:Canvas/> </s:Application> The "Canvas" line fails to compile. However it's OK in a Flex Project. My question is, is there any way to use Canvas or other halo

问题 I need a way to programmatically record what source files are consumed in an MXMLC compile. Ideally there would be a flag to pass to MXMLC to have it report the complete list of source files it is compiling, but there doesn't seem to be such a flag. It seems generally you just pass a main.mxml file to MXMLC and it goes off and compiles everything it needs to without telling you what it's doing. As far as I can tell, you also cannot explicitly list the files for it to compile; it will resolve

问题 I find it much easier to write MXML classes with embedded Script than trying to make an actionscript file. I was wondering however what kind of overhead there is of using an MXML file - in terms of file size. I'm not especially concerned about performance, but if that is relevant would be interested in any findings. Obviously I'm talking about UI components that have layout. MXML is MUCH easier to visualize and modify but I'm unclear exactly what it compiles down too. I'm hoping there is a

问题 I need some help in adding the replace all functionality into my Flex project. I would prefer doing this in a way that is as natural as possible. What I want to achieve is to be able to run this code (with the Flex compiler) "aabbaaba".replaceAll("b","c") and get "aaccaaca" . Also I want to chain replaceAll calls. Note: I won't be actually replacing b s with c s, but various string that will not be known at coding time! What I don't want: 1. Use regular expressions with the global flag. The

问题 This should be trivial, but I can't seem to figure out a way to do this. I have a DataGrid, and what I would like to do, is when a user clicks on a row to select it, check a certain condition, and if it's met prevent the row from getting selected and keep the old selection intact. Thanks! 回答1: I didn't test it, but it should work using event.preventDefault() and/or event.stopImmediatePropagation() on the GridSelectionEvent.SELECTION_CHANGING event. //stupid function but used for example

问题 In as3 What is the difference between calling stage.width and stage.stageWidth I read somewhere that if we have nothing on stage then the value of stage.width is 0 , but what happen when I have nothing on stage but loading contents dynamically on stage? I have tried this and when i have loaded content dynamically on stage then i have got stage.width=value; // where value is dynamic number Can anyone explain this?? thanks. 回答1: According to the Adobe Reference for the Stage Class: stage.width
