从父SWF AS3访问变量 [英] as3 access variable from parent swf

问题描述

我试图让孩子读其父的增值分销商，反之亦然。 家长有没有问题看孩子的增值经销商，但由于某种原因，孩子只能得到未定义作为一个答案......（而不是456）

I'm trying to let the child read its parent's vars and vice versa. The parent has no problems reading the child's vars, but for some reason the child gets only "undefined" as an answer...(instead of the "456")

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()

儿童（test1.swf）剧本

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为空 和影片剪辑（parent.parent）只吐出一个错误

parent.parent.parent is null and MovieClip(parent.parent) only spits out an error

我不知道什么是错的？ 我失去了一些东西？

I have no clue what's wrong... am I missing something?

推荐答案

试试这个：

在子SWF：

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.
}
