处理客户事件和 Async.asyncHandler() 的 flexunit

发布于 2024-10-04 21:26:21 字数 713 浏览 5 评论 0原文

任何人都知道 Async.asyncHandler() 是如何工作的，以及 Async.processOnEvent() 是否只能在 [Before] 方法中使用。（除了 Async.asyncHandler() 之外，任何人都知道一些有用的文档a href="http://docs.flexunit.org/" rel="nofollow">http://docs.flexunit.org/）。

我定义了一个名为 HelloCompo(extends Vbox) 的 MXML 组件，该组件定义了一个名为 hello() 的函数，在 hello() 中调度了一个名为 HelloEvent 的客户事件（事件类型刚刚命名为“hello”），并在另一个名为init() 监听了该事件，我想测试该事件是否被正确调度。所以我有以下测试：

var helloCompo = new HelloCompo();

helloCompo.hello();

helloCompo.addEventListener("hello", Async.asyncHandler(this, handleHello, 1000, null, handleTimeOut));

测试总是会执行handleTimeOut方法（意味着HelloEvent没有被调度，但是当helloCompo.hello()执行时，它真的被调度了，所以出了什么问题？）

Any one know how does Async.asyncHandler() work and if Async.processOnEvent() can only used in [Before] method.(Any one know some helpful document besides http://docs.flexunit.org/).

I define a MXML component named HelloCompo(extends Vbox), and the component define a function named hello(), in the hello() dispacthed a customer event named HelloEvent(the event type just named "hello"), and in another function named init() listened for the event, I want to test whether the event is dispatched properly or not. So I have the test following:

var helloCompo = new HelloCompo();

helloCompo.hello();

helloCompo.addEventListener("hello", Async.asyncHandler(this, handleHello, 1000, null, handleTimeOut));

The test will always excute the handleTimeOut method(means the HelloEvent is not dispatched, but when helloCompo.hello() excute, it really dispacthed, so what's going wrong?)
