引用，使得该ExternalInterface.call来调用的JavaScript函数的HTML对象 [英] referencing the html object that made the ExternalInterface.call to the javascript function called

问题描述

我道歉，如果我的术语是关闭的，我的动作技能是pretty的弱酱。

i apologize if my terminology is off, my actionscript skills are pretty weak sauce.

所以，我有一些动作，使一个

so, i have some actionscript that makes a

ExternalInterface.call（'someFunction'）;

ExternalInterface.call('someFunction');

电话。

是否有可能引用，使得调用someFunction的HTML对象直接使用ExternalInterface.call调用？

is it possible to reference the html object that made the call to someFunction directly using the ExternalInterface.call call?

假设，使得调用也物体有一定的回调（通过ExternalInterface.addCallback）是通过JavaScript访问。

Assume that the object that makes the call also has some Callbacks (via ExternalInterface.addCallback) that are accessible via javascript.

目前：

Actionscript source

ExternalInterface.call("someFunction");
ExternalInterface.addCallback("someCallback",someASfunction);

Javascript source

function someFunction(){
    document.getElementById('idOfSWFObject').someCallback();
}

我想必须有一个方法：

I'm thinking there must be a way of:

Actionscript source

ExternalInterface.call("someFunction",THE_OBJECT_MAKING_THE_CALL);
ExternalInterface.addCallback("someCallback",someASfunction);

Javascript source

function someFunction(o){
    o.someCallback();
}

再次，遗憾的术语。试图用尽可能多的关键字搜索的未来蕾丝吧。

once again, sorry about the terminology. tried to lace it with as many keywords for future searches.

谢谢！

推荐答案

我猜你是在谈论ExternalInterface.objectID。该属性返回Flash容器相关的ID中的对象或嵌入的标签。

I guess you are talking about ExternalInterface.objectID. This property returns an id associated with flash container in object or embed tag.

<一个href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html?filter_flex=4.1&filter_flashplayer=10.2&filter_air=2.en#objectID" rel="nofollow">http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html?filter_flex=4.1&filter_flashplayer=10.2&filter_air=2.en#objectID

我建议你也应该通过someCallback给你的JS方法的名称。这样，就没有必要到c很难$ C $的JS。

I suggest that you should also pass the name of "someCallback" to you JS method. This way there will be no need to hardcode it in JS.

下面是一个例子

// Actionscript source

const jsMethodName:String = "someFunction";
const asCallbackName:String = "someCallback";
ExternalInterface.call(jsMethodName+"(document.getElementById("++")"++");");
ExternalInterface.addCallback(asCallbackName,someASfunction);

// Javascript source

function someFunction(flashId, callbackName) 
{
    var flashContainer = document.getElementById(flashId);
    flashContainer["callbackName"]();
}

编辑：如果您真的想获得一个对Flash DOM对象someFunction参数，可以实现在一个有点棘手的方式（我宁愿没有，但只是为你的兴趣）。

If you really want to get a reference to flash DOM object in someFunction arguments, you may achieve it in a bit tricky way (I would rather not, but just for your interest).

// Actionscript source

const jsMethodName:String = "someFunction";
const asCallbackName:String = "someCallback";
ExternalInterface.addCallback(asCallbackName,someASfunction);

ExternalInterface.call(
    "function(){"+ 
        jsMethodName+"("+
            "document.getElementById('"+ExternalInterface.objectID+"'),"+
            "'"+asCallbackName+"'"+
        ");"+
    "}"
);    

// Javascript source

function someFunction(flashContainer, callbackName) 
{
    flashContainer[callbackName]();
}

这样你注入从闪存一些JS code到JS。它的工作原理，但看起来凌乱。

This way you inject some JS code from flash into js. It works, but looks messy.
