如何通过动作脚本在外部HTML内容中获取并设置选定的单选按钮？

Question

I am new in flash and as3.

I am using an external html file through mx:html in Flash.

<fx:Script>
...
myHTML.location = "../assets/myHTML.htm";
...
</fx:Script>

<mx:HTML id="myHTML"/>

There are 3 radio buttons in this myHTML.htm file.

Is there any way to get and set the selected radio button through actionscript?

I am developing an AIR application. And as far as I come to know that the ExternalAPI will not work. Actually I want to use multiple HTML files of quiz question with radio buttons.

Answer 1

由于缺乏MXML经验及其应用，有些犹豫，我将研究AS3的ExternalInterface http://help.adobe.com/zh_CN/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html及其在Flex中使用http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_4.html

Answer 2

Nobody tell me this simple code:

In Flex/Actionscript:

function initial():void
{
html.addEventListener(Event.HTML_DOM_INITIALIZE,loaded);
}

function loaded(e:Event):void
{
html.htmlLoader.window.getOption = getOption;
}

function setvalue():void
{
html.htmlLoader.window.selectradio(radioButtonID);
}

function getOption(value:String):void
{
trace(value);
}

in HTML file

<SCRIPT LANGUAGE="JavaScript">
function selectradio(selectvalue)
{
document.getElementById(selectvalue).checked = true;
}
</SCRIPT>

<INPUT ID="a" TYPE="radio" NAME="op" onClick="getOption('a')"
