问题 We are converting a Flex application to use some REST APIs. When adding the mx.rpc.http.HTTPService class to the code, the SWF binary output grew from 175KB to 260KB. This is an unacceptable hit. Is there any better way to do lightweight REST calls from a Flex app? Are we better off using an external interface JS just to make the calls from there? 回答1: flash.net.URLLoader is built into the runtime and won't cause any increase in filesize. I've used it as a JSON client before, so you shouldn't

问题 When using .contains() on an ArrayCollection in Flex, it will always look at the memory reference. It does not appear to look at an .equals() method or .toString() method or anything overridable. Instead, I need to loop through the ArrayCollection every time and check each individual item until I find what I'm looking for. Does anyone know why Flex/ActionScript was made this way? Why not provide a way from people to use the contains() method the way they want? 回答1: Couldn't you just extend

问题 I've recently started making a game in FlexBuilder. The game is currently a Flex project. Is there any downside to using Flex as opposed to just Actionscript? A friend of a friend told me that Flex is slower than an Actionscript project. I've been unable to validate this on the internet; is there any truth to that claim? Thanks! 回答1: If you're developing a game, you should be using an ActionScript project. Flex is to be used only for data driven applications and user interfaces. The flex

问题 I'm new to flex , so forgive me if this is a dumb question. Right now I'm using custom events to pass data from one component to another. My problem is that events only bubble up.

Application MXML Component 1 Component 2 Component 3 回答1: If a piece of data is required by all components in a graph/tree, your best

问题 I'm currently working on a Flex 3.0 project in which I have to display some input text with minimum formatting. We are considering to use "markdown" as the chosen way to express this formatting, now I would like to know if there is a library for this purpose. 回答1: You could use my AS3 port of John Fraser's Showdown. // Usage: var text = "Markdown *rocks*."; var html = Showdown.makeHtml(text); // <p>Markdown <em>rocks</em>.</p> 来源： https://stackoverflow.com/questions/820212/actionscript

问题 I'm currently experimenting with loading external SWF files from both an standard AS3 application, and an AIR application. It seems that the AIR application doesn't act the same way a standard SWF run by the Flash Player does. According to the documentation, the applicationDomain property of LoaderContext is usable in an AIR application too, but it just seems to be not working. I have the following code : package { import flash.display.Loader; import flash.display.LoaderInfo; import flash

问题 Folks, I have designed an Adobe AIR application. I want to show some preloader on it, before it opens up. Can anyone guide me with tutorials on preloader aimed for AIR specifically or any already built in ones? Thanks 回答1: With AIR I can think of a couple of ways to achieve that: 1. with native windows Set the 'visible' attribute of your main WindowedApplication to 'false'. On 'creationComplete' event spawn a new Window that contains your splash screen. Perform the necessary logic before
