Question

我有一个项目，它成功地从XML文件加载图像以制作Flash库。然而，它似乎突然停止了工作。我已经完成了故障排除，发现这是因为SWF不再加载XML文件。但是，我没有搞砸SWF。我进入了FLA文件，代码是一样的。这是它的参考。

var strTitle = "THIS IS TITLE TEXT";
var strDescription = "This is descriptive";
var intCurrent = 0;
var arrDescription = new Array();//Stores descriptions
var arrTitle = new Array();//Stores titles
var arrMainLoc = new Array();//Stores image locations
var arrThumbLoc = new Array();//Stores thumb locations

var intCurrent:Number = 0;//Used to store the number passed from the button press

stop();
System.security.allowDomain("http:/gretchencomlydesign.com");

myPhoto = new XML();
myPhoto.ignoreWhite = true;
myPhoto.load("imgDATA.xml");
myPhoto.onLoad = function(success)
{
trace("loaded");
var intImageCount = myPhoto.firstChild.childNodes.length;
for (i = 0; i < intImageCount; i++)
{
    arrDescription[i] = myPhoto.firstChild.childNodes[i].attributes.desc;
    arrTitle[i] = myPhoto.firstChild.childNodes[i].attributes.titl;
    arrMainLoc[i] = myPhoto.firstChild.childNodes[i].attributes.main;
    arrThumbLoc[i] = myPhoto.firstChild.childNodes[i].attributes.thumbs;
    //trace(arrTitle[i]);   //Tests Loaded titles
    //trace(arrDescription[i]);    //Tests Loaded descriptions
}
play();
//trace(myPhoto.firstChild.childNodes[0].attributes.desc);
  };
  myPhoto.onLoad = function(false)
  {
    trace("XML failed to load");
  };

它确实加载了，但现在将不再有效。我检查过，服务器是Apache，我的情况匹配。我的文件名为“imgDATA.xml”。有没有人经历过这样的事情？

编辑：值得一提的是，我尝试更改目标XML文件的名称和要加载的XML文件，但仍然无法加载。

编辑2：调整SWF代码后，我得到了这个输出

loaded
onData:<pop>



<img titl="0" desc="" main="pics/pop/main/0.jpg" thumbs="pics/pop/thumbs/0.jpg"/>

<img titl="1" desc="" main="pics/pop/main/1.jpg" thumbs="pics/pop/thumbs/1.jpg"/>

<img titl="2" desc="" main="pics/pop/main/2.jpg" thumbs="pics/pop/thumbs/2.jpg"/>

<img titl="3" desc="" main="pics/pop/main/3.jpg" thumbs="pics/pop/thumbs/3.jpg"/>





</pop>

这是我的XML文件：

<pop>

<img titl="0" desc="" main="pics/pop/main/0.jpg" thumbs="pics/pop/thumbs/0.jpg"/>
<img titl="1" desc="" main="pics/pop/main/1.jpg" thumbs="pics/pop/thumbs/1.jpg"/>
<img titl="2" desc="" main="pics/pop/main/2.jpg" thumbs="pics/pop/thumbs/2.jpg"/>
<img titl="3" desc="" main="pics/pop/main/3.jpg" thumbs="pics/pop/thumbs/3.jpg"/>


</pop>

服务器的根目录（承载XML文件的文件）是否有crossdomain.xml个文件？如果没有，您需要添加它并将其内容设置为：

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
   <allow-access-from domain="*" secure="false" />
</cross-domain-policy>

修改

尝试设置所有事件处理程序以更好地了解正在发生的事情，然后在此处发布跟踪语句的结果。

myPhoto.onData = function(src:String) { trace("onData:" + src); } myPhoto.onHTTPStatus = function(httpStatus:Number) { trace("httpStatus:" + httpStatus); } myPhoto.onLoad = function(success:Boolean) { trace("onLoad:" + success); }

修改

尝试向XML文件添加标头，否则Flash可能不知道它的XML数据：

<?xml version="1.0"?> <pop> <img titl="0" desc="" main="pics/pop/main/0.jpg" thumbs="pics/pop/thumbs/0.jpg"/> <img titl="1" desc="" main="pics/pop/main/1.jpg" thumbs="pics/pop/thumbs/1.jpg"/> <img titl="2" desc="" main="pics/pop/main/2.jpg" thumbs="pics/pop/thumbs/2.jpg"/> <img titl="3" desc="" main="pics/pop/main/3.jpg" thumbs="pics/pop/thumbs/3.jpg"/> </pop>

Answer 2

我最终解决了这个问题。我只需要调整代码，使其成为一个函数，然后调用函数。这让它解析了。这是工作代码

var strTitle = "THIS IS TITLE TEXT";
var strDescription = "This is descriptive";
var intCurrent = 0;
var arrDescription = new Array();//Stores descriptions
var arrTitle = new Array();//Stores titles
var arrMainLoc = new Array();//Stores image locations
var arrThumbLoc = new Array();//Stores thumb locations

var intCurrent:Number = 0;//Used to store the number passed from the button press

stop();




function processXMLData(success)
{
  if (success)
  {trace("loaded");
    var intImageCount = myPhoto.firstChild.childNodes.length;

    for (i = 0; i < intImageCount; i++)
    {
        arrDescription[i] = myPhoto.firstChild.childNodes[i].attributes.desc;
        arrTitle[i] = myPhoto.firstChild.childNodes[i].attributes.titl;
        arrMainLoc[i] = myPhoto.firstChild.childNodes[i].attributes.main;
        arrThumbLoc[i] = myPhoto.firstChild.childNodes[i].attributes.thumbs;
        trace(arrTitle[i]);//Tests Loaded titles
        trace(arrDescription[i]);//Tests Loaded descriptions

    }
    trace(arrTitle[0]);
    play();
    //trace(myPhoto.firstChild.childNodes[0].attributes.desc);
}    else
  {
    content="Today's news is not found";
  }
  }



var myPhoto=new XML();
myPhoto.ignoreWhite=true;
myPhoto.onLoad=processXMLData;
myPhoto.load("imgDATA.xml");
stop();

我的XML停止在Flash中加载
