How does the JavaScript variable get to Flash? JavaScript变量如何到达Flash？

It looks like there is an embed that is retrieved with getElementById , and that element has all of these extra methods on it like appendText or setCharSet that do not show up in Chromes debug console. 看起来好像有一个用getElementById检索的embed ，并且该元素上具有所有这些额外的方法，例如appendText或setCharSet ，这些方法不会显示在Chrome调试控制台中。 I figure the embed tag is maybe special and can somehow call native ActionScript methods, but that is just a guess. 我认为embed标签可能很特殊，并且可以以某种方式调用本机ActionScript方法，但这只是一个猜测。

Could someone please explain to me how this works? 有人可以告诉我这是如何工作的吗？

EDIT: I should have said that if I create an embed element in Chrome and scroll through its methods, I do not see things like appendText . 编辑：我应该说，如果我在Chrome中创建一个embed元素并滚动浏览其方法，则不会看到诸如appendText东西。 However, if I console log the embed that was retrieved via getElementById and console.log appendText , it says function() { [native code] } . 但是，如果我控制台记录通过getElementById和console.log appendText检索到的embed ，它将显示function() { [native code] } 。

You use ExternalInterface to communicate between the swf and the swf container, ie the html page. 您可以使用ExternalInterface在swf和swf容器（即html页面）之间进行通信。

You do it exactly like this: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html 您完全按照以下步骤操作： http : //help.adobe.com/zh_CN/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html
