How to call flash actionscript callback method from javascript?
提问by Tricks By Sam
I tried to call a flash callback method from JavaScript. But it seems not working. The flash action script example code is like below [Simplified]:
我试图从 JavaScript 调用 flash 回调方法。但它似乎不起作用。flash动作脚本示例代码如下[简化]：
import flash.events.ActivityEvent;
import flash.events.StatusEvent;
import flash.external.ExternalInterface;
var test_var = ExternalInterface.addCallback("js_method_to_call", flash_method);
function flash_method()
{
return "test";
}
The javascript example code is written below [Simplified]:
javascript示例代码写在[简化]下面：
function callFlashMethod(){
var flashFile = eval("window.document.test");
flashFile.js_method_to_call;
}
function loadTest(){
swfobject.embedSWF("test.swf", "test", "1", "1", "10.0.0", false);
}
$(document).ready(function(){
loadTest();
callFlashMethod();
});
It is always display the error in fire bug console "flashFile.js_method_to_call is not a function".
它总是在 fire bug 控制台中显示错误“flashFile.js_method_to_call is not a function”。

Here's something that should work really good:
这里有一些应该非常有效的东西：
Use SWFObject.js for embedding the Flash content:
// Embedding through SWFObject rocks in comparison with Adobe shits: var flashvars = {}; var params = {}; params.menu = "false"; params.salign = "t"; params.scale = "noscale"; params.wmode = "transparent"; params.allowScriptAccess = "always"; var attributes = {}; attributes.id = "${swf}"; swfobject.embedSWF("${swf}.swf", "flashDiv", "${width}", "${height}", "9.0.0", "", flashvars, params, attributes);Use this for the HTML:
<body> <div id="flashDiv"></div> </body>To call your Flash method use this pattern:
// Functions needed for calling Flex ExternalInterface function thisMovie(movieName) { if (navigator.appName.indexOf("Microsoft") != -1) { return window[movieName]; } else { return document[movieName]; } }Call the Flash method:
function callFlashMethod() { thisMovie("${swf}").js_method_to_call(); }
使用 SWFObject.js 嵌入 Flash 内容：
// Embedding through SWFObject rocks in comparison with Adobe shits: var flashvars = {}; var params = {}; params.menu = "false"; params.salign = "t"; params.scale = "noscale"; params.wmode = "transparent"; params.allowScriptAccess = "always"; var attributes = {}; attributes.id = "${swf}"; swfobject.embedSWF("${swf}.swf", "flashDiv", "${width}", "${height}", "9.0.0", "", flashvars, params, attributes);将此用于 HTML：
<body> <div id="flashDiv"></div> </body>要调用您的 Flash 方法，请使用以下模式：
// Functions needed for calling Flex ExternalInterface function thisMovie(movieName) { if (navigator.appName.indexOf("Microsoft") != -1) { return window[movieName]; } else { return document[movieName]; } }调用 Flash 方法：
function callFlashMethod() { thisMovie("${swf}").js_method_to_call(); }

You get a reference to your embedded SWF object and use it to make a call to your as3 method.
您获得对嵌入的 SWF 对象的引用，并使用它来调用您的 as3 方法。
//AS3 Code
ExternalInterface.addCallback("helloFromJS",helloFromJS);
private function helloFromJS():void
{
trace("JS is saying hello");
}
//HTML Code
<object width="100%" height="100%" id="Test">
<param name="movie" value="Test.swf"/>
//JS Code
var swfObject = document.getElementById("Test");
swfObject.helloFromJS();

I'm not sure about this line:
我不确定这一行：
var flashFile = eval("window.document.test");
I would use:
我会用：
var flashFile = document.getElementById("test");
Also, I'm guessing this was just a typo when pasting here, but flashFile.js_method_to_call;should be flashFile.js_method_to_call();
另外，我猜这只是在这里粘贴时的一个错字，但flashFile.js_method_to_call;应该是flashFile.js_method_to_call();
