	</div> 
</s:form>
<iframe name='hidden_frame' id="hidden_form" style="display:none"></iframe>
	<script type="text/javascript">
		function uploadcanshu(){
			var uploads = $("#uuppload").val();
			if(uploads!=null&&uploads!=""){
			
			$("#hidden_frame").submit();
			$("#hidden_form").one("load",function () {
			<span style="white-space:pre">	</span>var ahtml=$("#hidden_form").contents().find("body")[0].outerHTML;
			<span style="white-space:pre">	</span>var data=$("#hidden_form").contents().find("body").html();
			<span style="white-space:pre">	</span>var bb=$("#hidden_form").contents().find("body").find("pre").html();
			<span style="white-space:pre">	</span>$("#jishucanshu").val(data);
			});
			}else{
			<span style="white-space:pre">	</span>alert("上传失败，请重新上传！");
			}
		}
</script>

action类里的代码：

（public class UploadAction extends ActionSupport）

ServletActionContext.getResponse().setContentType("text/html;charset=UTF-8");
ServletActionContext.getResponse().setCharacterEncoding("UTF-8");
ServletActionContext.getResponse().setHeader("Cache-Control","no-cache");

ServletActionContext.getResponse().setHeader("Charset","UTF-8");

ServletActionContext.getResponse().getWriter().write("<BODY>"+strupload+"</BODY>");
