从setTimeout调用时,AS3 ExternalInterface / navigateToUrl弹出窗口被阻止

这个问题让我撕裂了我的头发。

症状:从外部界面和navigateToURL组合间歇性地阻止/通过弹出窗口。

问题:Flash(或浏览器......不确定)不会在时间范围和/或事件持续时间之外触发弹出窗口。

环境:我有一个需要通过zendAMF发送数据的应用,做一些处理并发送回flash播放器。在响应上,如果满足某些条件,则触发弹出窗口。在响应中被阻止的相同代码直接从鼠标事件触发器开始工作。

所以我设置了一个基本情况:6个按钮,调用3个方法。 3个按钮将直接调用该方法(全部完全打开窗口),其他三个将获得数值步进器的值,并使用setTimeout(openWinMethod,NumericStepper.value)来模拟来自zendAMF响应的延迟调用。

UPDATE :如果我首先选择'navigateToURL,no delay'按钮,关闭该窗口,然后尝试任何其他延迟调用 - 它们可以正常工作。它就像浏览器接受你在某个时候点击打开一个窗口,因此可以从延迟然后打开。 (仅限firefox)

所有三个使用延迟都将被阻止(firefox和chrome),而所有三个直接打开。 Safari - 以及已记录的内容,仅适用于使用navigateToURL

的2种方法

感兴趣:html包装器中的js函数将被称为外部接口以打开一个窗口。没有延迟,这工作。延迟时,将调用js函数(由某些警报语句验证),但从未生成新窗口。

我面临两种选择: 1 - 当我从zenAMF收到我的回复时,更改流程以要求用户单击继续,或 2 - 找出发生这种情况的原因并加以解决(最好)

请阅读:User Interaction Requirements

您会注意到,在“弹出窗口”下,externalInterface和navigatetoURL都列为仅响应用户交互。如果你运行一个花费太长时间的脚本,基本上你正在做的事情将被阻止。

如果你想做这样的事情,那么id要么使用ExternalInterface调用一个javascript来调用和响应外部页面信息,然后用布尔值回复到flash或打开弹出窗口然后让它调用并回复外部页面(如果没有,则显示错误信息等)。

确切地取决于你对zend的所作所为。
