Question

我试图让孩子读取其父母的变量，反之亦然。父母在阅读孩子的变种时没有任何问题，但出于某种原因，孩子只能得到未定义的＃34;作为答案...（而不是＆＃34; 456＆＃34;）

父脚本

var mySwf
var masterVar=456
function startLoad() { 
    var myLoader:Loader = new Loader(); 
    var mRequest:URLRequest = new URLRequest("test1.swf"); 
    myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
    myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
    myLoader.load(mRequest); 
} 

function onCompleteHandler(loadEvent:Event) {
    mySwf=loadEvent.currentTarget.content
    addChild(mySwf);
    trace(mySwf.slaveVar)//123
}

function onProgressHandler(mProgress:ProgressEvent) {
}
startLoad()

Child(test1.swf)脚本

var slaveVar=123

trace(Object(parent))//[object Loader]
trace(Object(parent.parent))//[object Object]
trace(Object(parent.parent).masterVar)//undefined
trace(Object(this.parent.parent).masterVar)//undefined

parent.parent.parent为null 和MovieClip（parent.parent）只发出错误

我不知道什么是错的...... 我错过了什么吗？

试试这个：

在孩子们的孩子们：

var theParent:Object;
addEventListener(Event.ADDED_TO_STAGE, onAdded);
function onAdded(e:Event):void
{
    theParent = this.parent as Object
    trace(theParent.masterVar);
    //will work after child swf has been added to the display list of the parent file.
}

来自父swf的as3访问变量
