听起来您正在寻找 ExternalInterface.call().Adobe 有一篇文章介绍了如何使用它从 ActionScript 调用 JavaScript.

It sounds like you're looking for ExternalInterface.call(). Adobe has an article about how to use it to call JavaScript from ActionScript.

您还可以使用 ExternalInterface 将 ActionScript 公开给 JavaScript，并从 JavaScript 调用 SWF 的内部函数.

You can also use ExternalInterface to expose ActionScript to JavaScript and call functions internal to your SWF from JavaScript.

假设您有一个如下所示的 JavaScript 函数:

Let's say you have a JavaScript function that looks like this:

function specialAlert(msg) {
  alert(msg);
}

从您的 Flash 文件中，您可以像这样调用它:

From your flash file you can call it like this:

import flash.external.*;

ExternalInterface.call("specialAlert", "Hi mom!");

并且您的 JavaScript 函数应该被调用并提醒用户妈妈！".

And your JavaScript function should be called and alert the user "Hi mom!".
