问题 Is there a way to make synchronous calls using RemoteObject in Flex? 回答1: All IO in Flex is asynchronous. The typical pattern to deal with this is to use an AsyncResponder. For instance: var t:AsyncToken = remoteObject.methodCall(); t.addResponder(new AsyncResponder(resultEvent, faultEvent)); 回答2: think twice when u want it to be synchronous. Do u know what synchronous mean? it will FREEZE your application until it receive data. Unless u are pretty sure that your remote calling can receive

问题 Is there any way to implement waiting for, say, 3 seconds in ActionScript, but to stay within same function? I have looked setInterval, setTimeOut and similar functions, but what I really need is this: public function foo(param1, param2, param3) { //do something here //wait for 3 seconds //3 seconds have passed, now do something more } In case you wonder why I need this - it is a legal requirement, and no, I can't change it. 回答1: Use the Timer to call a function after 3 seconds. var timer

问题 I am trying to set the json content type on httpservice to make REST service return the json data.

问题 I am a Java developer who tries Flex. Here is my problem: I behave actionScript objects as hashmap but when the object do not have the property it gives exception: No such variable. Here I expect it gave me null, instead of giving exception. So do you know is there a way to handle it, namely check if the property is defined for object. trace( obj["2008-02"] ) // gives exception 回答1: Use something along the lines of if (myObject.hasOwnProperty("propertyName")) to check if the property exists.

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 We have an application in which the user has to enter a date who's value is no more than 30 days after the the current date (the date on which the user uses the application). This is a Flash application, therefore I need a way to add 30 days to the current date, and get the right date.
