Flex 4 - FlexGlobals.topLevelApplication

在Flex 3读取HTML页面的flashvars的变量需要使用Application.application，在Flex 4 SDK里使用FlexGlobals.topLevelApplication代替了Application.application。

Flex 4已经使用swfobject了：

<script type="text/javascript">     var swfVersionStr = "10.0.0";     var xiSwfUrlStr = "playerProductInstall.swf";     var flashvars = {};     flashvars.firstname = "Nick";     flashvars.lastname = "Danger";     var params = {};     params.quality = "high";     params.bgcolor = "#ffffff";     params.allowscriptaccess = "sameDomain";     var attributes = {};     attributes.id = "TestProject";     attributes.name = "TestProject";     attributes.align = "middle";     swfobject.embedSWF(         "FlashVarTest.swf", "flashContent", "100%", "100%", swfVersionStr,         xiSwfUrlStr, flashvars, params, attributes);     swfobject.createCSS("#flashContent", "display:block;text-align:left;"); </script>var first_name : String = FlexGlobals.topLevelApplication.parameters.firstname;var last_name : String = FlexGlobals.topLevelApplication.parameters.lastname;
