每天学一点flash（26） flash cs 3制作air程序例子（2）

System.useCodePage = true;//防止乱码
mytxt.text="代码笔记本";
var loader:URLLoader=new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;//控制文本格式下载
try{
loader.load(new URLRequest("mytext/welcome.txt"));
}
catch(e:TypeError)
{trace("错误了");}
button1.addEventListener(MouseEvent.CLICK,mouseevent);
button2.addEventListener(MouseEvent.CLICK,mouseevent_2);
button3.addEventListener(MouseEvent.CLICK,mouseevent_3);
button4.addEventListener(MouseEvent.CLICK,mouseevent_4);
button5.addEventListener(MouseEvent.CLICK,mouseevent_5);
button6.addEventListener(MouseEvent.CLICK,mouseevent_6);
function mouseevent(event:MouseEvent):void{

loader.load(new URLRequest("mytext/1.txt"));
mytxt.text=loader.data;
}

function mouseevent_2(event:MouseEvent):void{

loader.load(new URLRequest("mytext/2.txt"));
mytxt.text=loader.data;
}

function mouseevent_3(event:MouseEvent):void{

loader.load(new URLRequest("mytext/3.txt"));
mytxt.text=loader.data;
}
function mouseevent_4(event:MouseEvent):void{

loader.load(new URLRequest("mytext/4.txt"));
mytxt.text=loader.data;
}
function mouseevent_5(event:MouseEvent):void{

loader.load(new URLRequest("mytext/5.txt"));
mytxt.text=loader.data;
}

function mouseevent_6(event:MouseEvent):void{

loader.load(new URLRequest("mytext/6.txt"));
mytxt.text=loader.data;
}

这里主要使用到的是flash.net包的URLLoader ，URLRequest 鼠标类等等

但是这里我要说的是，异常处理

try{

loader.load(new URLRequest("mytext/welcome.txt"));

}

catch(e:TypeError)

{trace("错误了");

假如没有这个try 和catch处理TypeError 经常我们会看到TypeError异常的对话框

异常处理在as 3.0里面需要建立起来，我们应该有意识注意到这个情况

System.useCodePage = true;//防止乱码
mytxt.text="代码笔记本";
var loader:URLLoader=new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;//控制文本格式下载
try{
loader.load(new URLRequest("mytext/welcome.txt"));
}
catch(e:TypeError)
{trace("错误了");}
button1.addEventListener(MouseEvent.CLICK,mouseevent);
button2.addEventListener(MouseEvent.CLICK,mouseevent_2);
button3.addEventListener(MouseEvent.CLICK,mouseevent_3);
button4.addEventListener(MouseEvent.CLICK,mouseevent_4);
button5.addEventListener(MouseEvent.CLICK,mouseevent_5);
button6.addEventListener(MouseEvent.CLICK,mouseevent_6);
function mouseevent(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/1.txt"));
mytxt.text=loader.data;}
catch(e:TypeError)
{trace("错误了");}
}

function mouseevent_2(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/2.txt"));
mytxt.text=loader.data;
}
catch(e:TypeError)
{trace("错误了");}
}

function mouseevent_3(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/3.txt"));
mytxt.text=loader.data;
}
catch(e:TypeError)
{trace("错误了");}
}

function mouseevent_4(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/4.txt"));
mytxt.text=loader.data;}
catch(e:TypeError)
{trace("错误了");}
}

function mouseevent_5(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/5.txt"));
mytxt.text=loader.data;
}
catch(e:TypeError)
{trace("错误了");}
}

function mouseevent_6(event:MouseEvent):void{
try{
loader.load(new URLRequest("mytext/6.txt"));
mytxt.text=loader.data;}
catch(e:TypeError)
{trace("错误了");}
}

效果如下：

当中主要使用Button组件

与textarea文本框组件，加上一些外部加载的方法调用，开发出来的flash air桌面应用程序 ，最后一步当然是打包

最后是安装 测试。一个简单桌面应用程序就出现了 ，有趣吧
