flex嵌套html-----flex-iframe
在开发中，遇到需要在flex中嵌入activex，先前做法是直接把控件的object对象直接放在flex的html-template中，其实这样是可以实现的，只不过这种做法本质应该不属于我们需要的：flex页面最后在html中显示，并占据整个html页面，将object直接放在html-template中，flex与object共同构成html页面，并不是真正意义上的嵌套。而采用flex-iframe（ panel 嵌入flex-iframe）在flex-iframe中添加html页面，可以将其真正嵌套在flex中。
?
首先去http://code.google.com/p/flex-iframe/下载flex-iframe包，并导入项目。这个包里有很多例子，很容易看懂。但是在使用中要注意很多问题，下面列举我所遇到的问题?
1：嵌入的html页面部分在360 、opera等都可以显示，但是在ie中显示为空白。
? 解决方法：根据网上前辈的方法，将例子里的html-template中的AC_OETags.js导入，并添加
<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 globalsvar hasRequestedVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);if ( hasProductInstall && !hasRequestedVersion ) {// DO NOT MODIFY THE FOLLOWING FOUR LINES// Location visited after installation is complete if installation is requiredvar 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", "${width}","height", "${height}","align", "middle","id", "${application}","quality", "high","bgcolor", "${bgcolor}","name", "${application}","wmode", "opaque","allowScriptAccess","sameDomain","type", "application/x-shockwave-flash","pluginspage", "http://www.adobe.com/go/getflashplayer");} else if (hasRequestedVersion) {// if we've detected an acceptable version// embed the Flash Content SWF when all tests are passedAC_FL_RunContent("src", "${swf}","width", "${width}","height", "${height}","align", "middle","id", "${application}","quality", "high","bgcolor", "${bgcolor}","name", "${application}","wmode", "opaque","allowScriptAccess","sameDomain","type", "application/x-shockwave-flash","pluginspage", "http://www.adobe.com/go/getflashplayer"); } 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 }// --></script>?注意，这样之后你会发现在页面中你会看到2个一模一样的界面，这个主要是你在添加上述代码已经将flex.swf载入，而原来的html-template中也载入了，因此需要将原来的那部分删除。
2 嵌入的页面右侧有滚动条
在嵌入的页面中添加 <body STYLE="overflow-x: hidden; overflow-y: hidden;">，在嵌入控件object时，同时可以调整其高度进行控制

对于如何使用flex-iframe，很简单，看看例子就知道了。嗯? 目前就这些 ，基本能解决项目的问题了，以后遇到再研究
