Actionscript - 带有外部文本文件的 TLFTextField，文件运行时不显示任何内容

Question

完全公开，这是我 class 的作业。但是，这已经上交并评分。我真的只想知道为什么它不起作用。

对于 TLFTextField 和外部文件，我遵循了书中的步骤。有用。然后我需要再添加 2 个 TLFTextFields 和 2 个外部文本文件。当我现在运行它时， window 弹出但是是空白的。甚至我知道以前工作过的原始 TLFTextField 或文本文件显示也没有。我什至没有碰那个代码。没有错误。我不知道我哪里出错了。我的 class 朋友也有同样的问题。

我的代码如下：

import fl.text.TLFTextField;
import fl.controls.UIScrollBar;
import flash.net.URLLoader;
import flash.net.URLRequest;

import flash.events.Event;
import flash.text.TextFormat;
import flash.events.KeyboardEvent;

var t:TLFTextField = new TLFTextField();
var tf:TextFormat = new TextFormat();
t.width = 500;
t.height = 600;
t.background = true;
t.paddingTop = 20;
t.paddingLeft = 20;
t.paddingRight = 20;
addChild(t);

var textLoad:URLLoader = new URLLoader();
textLoad.addEventListener(Event.COMPLETE, textLoaded);
textLoad.load(new URLRequest("sample.txt"));

function textLoaded(e:Event):void
{
    var txt:String = URLLoader(e.target).data as String;
    t.text = txt;
    tf.color = 0x003300;
    tf.font = "Arial";
    tf.size = 14;
    t.setTextFormat(tf);
}

var cat:TLFTextField = new TLFTextField();
var cf:TextFormat = new TextFormat();
cat.width = 500;
cat.height = 600;
cat.background = true;
cat.paddingTop = 20;
cat.paddingLeft = 20;
cat.paddingRight = 20;
addChild(cat);

var catLoad:URLLoader = new URLLoader();
catLoad.addEventListener(Event.COMPLETE, catLoaded);
catLoad.load(new URLRequest("cat.txt"));

function catLoaded(e:Event):void
{
    var txt:String = URLLoader(e.target).data as String;
    cat.text = txt;
    cf.color = 0xFCE5CD;
    cf.font = "Arial";
    cf.size = 16;
    cat.setTextFormat(cf);
}

var doctor:TLFTextField = new TLFTextField();
var df:TextFormat = new TextFormat();
doctor.width = 500;
doctor.height = 600;
doctor.background = true;
doctor.paddingTop = 20;
doctor.paddingLeft = 20;
doctor.paddingRight = 20;
addChild(doctor);

var doctorLoad:URLLoader = new URLLoader();
doctorLoad.addEventListener(Event.COMPLETE, doctorLoaded);
doctorLoad.load(new URLRequest("doctor.txt"));

function doctorLoaded(e:Event):void
{
    var txt:String = URLLoader(e.target).data as String;
    doctor.text = txt;
    df.color = 0x68E9E5;
    df.font = "Arial";
    df.size = 16;
    doctor.setTextFormat(df);
}

Answer 1

我不在家取款机。据我所知，代码看起来很可靠，但我想我知道那里发生了什么。尝试连续加载文件，这意味着您首先加载 1 个文件，删除侦听器，然后加载文件 2，依此类推……我认为这应该可行。事件 EVENT.Complete 可能会触发所有其他侦听器。
