概要
我正在尝试制作一个包含多个相同SWF的网页。我有一个问题，它的加载速度太慢了(虽然下载时间还不错)。我在每个单元格中都有一个4x4表格，在iframe中嵌入了一个swf文件。 (注意:4 X 4表=> 16 SWFS)。
我的AS3代码非常简单:
package
{
import flash.display.Sprite;
import flash.system.System;
import flash.text.TextField;
public class ActionscriptProject extends Sprite
{
public function ActionscriptProject()
{
var txt:TextField = new TextField();
txt.x=0;
txt.y=0;
txt.width=5000;
txt.height=5000;
addChild(txt);
txt.htmlText+="<font size='45'>"+System.totalMemory/1048576 + " MB"+"</font>";
}
}
}
我正在使用以下html将其加载到iframe中:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Flash Testing</title>
</head>
<body>
<table border="1">
<tr>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
<td>
<iframe allowtransparency='true' scrolling='no' src='Flash/ActionscriptProject.html'></iframe>
</td>
</tr>
<tr>
...
</tr>
<tr>
...
</tr>
<tr>
...
</tr>
</table>
</body>
</html>
注意:ActionscriptProject.html只是Flash Builder与应用程序创建的标准html。但应The_asMan的要求，我将其包括在此处:

浏览器
在Chrome中没有问题。所有应用程序的加载速度都非常快(我估计会在3秒钟之内)。
在IE 8中，问题很小。
在IE 7和Firefox 3.6.17中，该页面的加载时间很长。我尚未在其他浏览器中进行过测试。
在Firefox中，页面加载大约需要34秒。

System.totalMemory报告说，瑞士法郎给我们带来了约42 MB的合并内存。这是Firebug中“网络”选项卡的屏幕截图:

问题
最佳答案
您是否尝试过构建本身会加载其他瑞士法郎的容器瑞士法郎？这样做可能会更快，因为这样Firefox不必处理一遍又一遍地初始化swf的开销。创建空白电影来加载一堆其他电影并将它们放置在网格中是相当简单的。
关于flash - Flash:同一页面上有许多相同的SWF，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6270900/
