怎么判断客户端是否安装了flash播放器

[shukewu]

有一个页面程序包含了一个flash，怎么给用户提醒，当客户端没有安装播放器或者播放器版本比较低的时候个客户提示。

flex发布的文件中包括一个html页面、一个swf档还有一个history文件夹以及playerProductInstall.swf，只要具备以上内容，就可以自动判断了。

把这些发在服务下面就可以了嘛？

只要保证发布文件的结构就可以，你不妨卸载flash player试试。

swfObject可以方便的用来检测是否有FLASH PLAYER

[清风水岸]

这个嵌入浏览器时由解释器自动执行的吧？似乎不必考虑

保留发布时与swf同时生成的html、playerProductInstall.swf和history文件夹即可，html里将需要的flash player版本和是否需要安装的代码都已经定义好了：

<script language="JavaScript" type="text/javascript">
<!--
// -----------------------------------------------------------------------------
// Globals
// Major version of Flash required
var requiredMajorVersion = 9;
// Minor version of Flash required
var requiredMinorVersion = 0;
// Minor version of Flash required
var requiredRevision = 124;
// -----------------------------------------------------------------------------
// -->
</script>

<script language="JavaScript" type="text/javascript">
<!--
// Version check for the Flash Player that has the ability to start Player Product Install (6.0r65)
var hasProductInstall = DetectFlashVer(6, 0, 65);

// Version check based upon the values defined in globals
var hasRequestedVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);

if ( hasProductInstall && !hasRequestedVersion ) {
	// DO NOT MODIFY THE FOLLOWING FOUR LINES
	// Location visited after installation is complete if installation is required
	var MMPlayerType = (isIE == true) ? "ActiveX" : "PlugIn";
	var MMredirectURL = window.location;
    document.title = document.title.slice(0, 47) + " - Flash Player Installation";
    var MMdoctitle = document.title;

	AC_FL_RunContent(
		"src", "playerProductInstall",
		"FlashVars", "MMredirectURL="+MMredirectURL+'&MMplayerType='+MMPlayerType+'&MMdoctitle='+MMdoctitle+"",
		"width", "100%",

	);
} else if (hasRequestedVersion) {
	// if we've detected an acceptable version
	// embed the Flash Content SWF when all tests are passed
	AC_FL_RunContent(
			"src", "GiftDesign",
			"width", "100%",
			"height", "100%",

	);
  } else {  // flash is too old or we can't detect the plugin
    var alternateContent = 'Alternate HTML content should be placed here. '
  	+ 'This content requires the Adobe Flash Player. '
   	+ '<a href=http://www.adobe.com/go/getflash/>Get Flash</a>';
    document.write(alternateContent);  // insert non-flash content
  }
// -->
