Question

我将ppt转换为swf格式，所以我需要找到该swf文件中的总帧数，如何获取它？以及如何进入给定swf文件的最后一帧？。

示例：这里我给了goto provious和next frame的源代码，但是我还没有得到第一帧，我怎么能得到它？有什么解决方案可以指导我...

在这里我怎样才能获得总帧数？请详细解释...先谢谢...

<head>
<script language="JavaScript">

function getFlashMovieObject(myFlashMovie)
{
if (window.document[myFlashMovie]) 
{
return window.document[myFlashMovie];
}
if (navigator.appName.indexOf("Microsoft Internet")==-1)
{
if (document.embeds && document.embeds[myFlashMovie])
  return document.embeds[myFlashMovie]; 
}
else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)
{
return document.getElementById(movieName);
}
}

//for Previous frame.....
function PrevFrameFlashMovie()
{ 
var flashMovie=getFlashMovieObject("myFlashMovie");
var currentFrame=flashMovie.TGetProperty("/",4);
var nextFrame=parseInt(currentFrame);
var prevfram =nextFrame-4;
flashMovie.GotoFrame(prevfram);
flashMovie.Play();
}

//for Next frame.....
function PlayFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.Play();
//embed.nativeProperty.anotherNativeMethod();
}

加载SWF后，您可以使用 _totalframes 属性获取total_no_of_frmaes。

var totalFrames=flashMovie._totalframes
