由于没有对我的网页名为myVar的一个​​全局JavaScript变量，我怎么可以从我的Flash影片使用JavaScript中访问的变量myVar的价值？

Given that there is a global javascript variable on my web page named myVar, how can I access the value of the variable myVar from within my flash movie using javascript?

我看到很多使用外部接口，以便执行从动作的javascript的例子，但我无法找到使用ActionScript回返回值插入Flash影片的例子。

I see plenty of examples of using external interface in order to execute javascript from actionscript, but I am unable to find examples of returning values back into the flash movie using actionscript.

在此先感谢。我希望我的问题是很清楚。

Thanks in advance. I hope my question is clear enough.

推荐答案

ExternalInterface的工作原理是允许JavaScript在电影中调用ActionScript函数，反之亦然。您可以选择接收返回值从调用函数后面。这里有一个很简单的例子：

ExternalInterface works by allowing JavaScript to invoke an ActionScript function in the movie, and vice-versa. You can optionally receive a return value back from the invoked function. Here's a very simple example:

JavaScript的：

JavaScript:

<script language="JavaScript">
    function getMyVar()
    {
        return myVar;
    }
</script>

闪存/ AS：

Flash/AS:

import flash.external.ExternalInterface;
var result:string = ExternalInterface.call("getMyVar");
