ExternalInterface.call（）没有得到返回值 [英] ExternalInterface.call() not getting return value

问题描述

我有一个JavaScript函数，该函数返回一个div的innerHTML。我试图调用从ActionScript这个函数和存储返回值。我知道的JavaScript函数被调用，因为没有显示的返回数据，返回到动作脚本，但是，是空的数据警报。我不知道是什么原因造成这一点。这里是什么，我试图做一个code例如：

I have a Javascript function that returns the innerHTML of a div. I am attempting to call this function from Actionscript and store the return value. I know that the Javascript function is being called because there is an alert that displays the return data, The data that is returned to Actionscript, however, is null. I am not sure what is causing this. Here is a code example of what I am attempting to do:

Javascript:
function JSFunc () {
     var x = document.getElementById("myDiv");
     alert(x.innerHTML);
     return x.innerHTML;
}

Actionscript:
import flash.external.*;
if (ExternalInterface.available) {
     var retData:Object = ExternalInterface.call("JSFunc");
     if(retData != null) {
          textField.text = retData.toString();
     } else {
          textField.text = "Returned Null";
     }
} else {
     textField.text = "External Interface not available";
}

就像我前面说的，警报显示了该div的内容，但在文本框的文本总是返回NULL，这意味着ExternalInterface的是可用的。我要补充一点，我只能在IE7和IE8测试。怎样做任何意见将是多少AP preciated。

Like I said earlier, the alert shows up with the contents of the div but the text in the textfield is always "Returned Null", meaning that the ExternalInterface is available. I should add that I can only test this in IE7 and IE8. Any advice on what to do would be much appreciated.

推荐答案

我一直有这个问题的来源必须做，我用嵌入Flash影片对象标记。我用接下来这个例子标签 http://www.w3schools.com/flash/ flash_inhtml.asp ，我把它改为匹配这个例子： HTTP ：//kb.adobe.com/selfservice/viewContent.do外部ID = tn_4150 ，然后我确信，我加号的对象和一切工作？

The source of the problem that I have been having has to do the object tag that I was using to embed the flash movie. I was using a tag that followed this example http://www.w3schools.com/flash/flash_inhtml.asp, I changed it to match this example: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_4150 and then I made sure that I added id to the object and everything worked.
