birt報表從session中取引數

自從註冊CSDN沒寫過一篇文章，今天閒來沒事，整理點小東西，寫下來。
birt從session中取從JSP傳遞的引數。
1、把JSP頁面獲得的引數放到session中，以下是簡短程式碼：
<body> <table> <input type="text" id="name" /> <input type="text" id="age"/> <input type="text" id="sex"/> <input type="button" onclick="subAajax()" /> </table>
<iframe name="reportIframe" id="reportIframe" height="82%"
style="width: 100%;z-index:9999;background: url(../images/public/8.gif);"frameborder="0" scrolling="auto" onload="change();">
</iframe></body><script type="text/javascript">
function subAajax(){
var name=document.getElementById("name");
var age=document.getElementById("age");
var sex=document.getElementById("sex"); var reportIframe = document.getElementById("reportIframe"); var url1="<%= request.getContextPath()%>" + "/frameset?__report=/report/"+reportName+"&__toolbar=false"; var con="&name="+name+"&age="+age+"&sex="+sex;$.ajax({ url:"<%= request.getContextPath()%>" +"/processRptdesign.do?method=addPosearchParam"+con, //處理頁面 type:"post", dataType:"html", success:function(msg){ $("#reportIframe").attr("src",encodeURI(url1)); } });
}
</script>public class ProcessParamAction extends DispatchAction {
public ActionForward addPosearchParam(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
Map<String, String> map=new HashMap<String, String>();
String name=request.getParameter("name");
String age=request.getParameter("age");
String sex=request.getParameter("sex");
map.put("stime",stime);
map.put("name",name);
map.put("age",age);
map.put("sex",sex);
request.getSession().setAttribute( "AppContextKey","numberWhere");
request.getSession().setAttribute("AppContextValue", map);
return null;
}
2、在報表中取session中的資料，在before open中寫如下程式碼獲取：
var name=numberWhere.get("name");
var age=numberWhere.get("age");
var sex=numberWhere.get("sex");
以上僅供參考，歡迎大家指正，共同學習
