如何在javascript里面获取 struts2标签的 <s:hidden /> 的值
<style type="text/css" media="screen"> html, body { height:100%; } body { margin:0; padding:0; overflow:auto; } #flashContent { display:none; } </style> <script type="text/javascript" src="js/swfobject/swfobject.js"></script> <script type="text/javascript" src="js/flexpaper_flash.js"></script> <script type="text/javascript"> var swfVersionStr = "10.0.0"; var xiSwfUrlStr = "playerProductInstall.swf"; alert(1); var applyResource = document.getElementById("apply").innerHTML; alert(2); alert(applyResource); var flashvars = { SwfFile : escape("resource/type/applyResource"), Scale : 0.6, ZoomTransition : "easeOut", ZoomTime : 0.5, ZoomInterval : 0.1, FitPageOnLoad : false, FitWidthOnLoad : true, PrintEnabled : false, FullScreenAsMaxWindow : false, ProgressiveLoading : true, PrintToolsVisible : true, ViewModeToolsVisible : true, ZoomToolsVisible : true, FullScreenVisible : true, NavToolsVisible : true, CursorToolsVisible : true, SearchToolsVisible : true, localeChain: "en_US" }; var params = { } params.quality = "high"; params.bgcolor = "#ffffff"; params.allowscriptaccess = "sameDomain"; params.allowfullscreen = "true"; var attributes = {}; attributes.id = "FlexPaperViewer"; attributes.name = "FlexPaperViewer"; swfobject.embedSWF( "FlexPaperViewer.swf", "flashContent", "960", "600", swfVersionStr, xiSwfUrlStr, flashvars, params, attributes); swfobject.createCSS("#flashContent", "display:block;text-align:left;"); </script> </head><body><%@ include file="top1.jsp" %><div id="wrapper"> <ul id="menu"> <li><a href="excellentCourse_list.jsp">首页</a></li> <li><a href="">精品课程一览</a></li> <s:iterator value="listcl"> <li ><a href="CourseLevel!getClApply?clid=<s:property value="clId" />"><s:property value="clApply" /></a></li> <s:hidden name="apply" value="%{clApplyResource}" /> </s:iterator> </ul> <div > <div id="flashContent"> </div></div></div>
貌似要加styleId属性，比如 <s:hidden styleId="apply" name="apply" value="%{clApplyResource}" />
才能用document.getElementById("apply").value来获取值。。
html的<input type="hidden"/>也要定义id属性，才能用document.getElementById("apply").value获取
[解决办法]
哎哟妈呀，原来是要获取~~~
var id=document.getElementById("updateId").value;
不过我记得，用s:hidden标签，不能使用value属性
自己在Action set获取一下~~~
