我正试图从php页面中获取一个变量，并将其发送到flash，然后在链接中使用。
我有问题，只是选择一个变量从打印函数，代码将有助于解释:
PHP页面<?
print"fbook=facebook";
print"tweet=twitter-test";
print"utube=youtube-test";
?>
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE,onLoaded);
loader.load(new URLRequest("../SC/FLA_tools-btn.php"));
var variables:URLVariables = new URLVariables();
fbook.addEventListener(MouseEvent.MOUSE_DOWN, mouseClickfbook);
tweet.addEventListener(MouseEvent.MOUSE_DOWN, mouseClicktweet);
youtube.addEventListener(MouseEvent.MOUSE_DOWN, mouseClickyoutube);
function onLoaded(evt:Event):void
{
var data:URLVariables = new URLVariables(evt.target.data);
variables.fbook = data.fbook;
variables.twitter = data.tweet;
variables.utube = data.utube;
}
function mouseClicktweet(event:MouseEvent):void
{
navigateToURL(new URLRequest('http://www.twitter.com/'+variables.twitter),"_Self");
}
function mouseClickfbook(event:MouseEvent):void
{
navigateToURL(new URLRequest('http://www.facebook.com/'+variables.fbook),"_Self");
}
function mouseClickyoutube(event:MouseEvent):void
{
navigateToURL(new URLRequest('http://www.youtube.com/'+variables.utube),"_Self");
}
它很好地收集了所有的数据，但它没有正确地打印出来，它在一个链接中打印出了php中的所有变量。例如:
如果我点击facebook图标，我将被带到http://www.facebook.com/facebooktweet=twitter-testutube=youtube-test，这也发生在其他图标(Youtube和Twitter)。
任何想法?
谢谢!
从PHP通过网络发送的原始数据大致如下:
fbook=facebook'n
tweet=twitter-test'n
utube=youtube-test'n
如果你想在URLVariables类中使用它，你需要对属性进行正确的URL编码。它们应该是这样的:
fbook=facebook&tweet=twitter-test&utube=youtube-test
修改你的PHP脚本如下:
<?
print"fbook=facebook&tweet=twitter-test&utube=youtube-test";
?>
那么你应该在Flash的那一边设置好
如何用不同的方式来处理?当您从flash应用程序请求php文件中的数据时，您可以指定您想要的特定数据。下面是一个这样的例子:
Main.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="init(event)">
<fx:Script>
