本文介绍如何在JSP页面之间传递参数，使用encodeURIComponent进行编码，并在目标页面A.jsp通过decodeURIComponent解码，将JSON字符串转换为对象。

jsp页面：跳转 A.jsp 页面参数编码：

encodeURIComponent(encodeURIComponent(JSON.stringify(data),"UTF-8"),"UTF-8")

<div  id="cirInfoExportInfoPage">
</div>

var toPageFormUrl =contextPath+"/A.jsp";
var exportInfoFormHtml="<form id=\"toPageForm\" method=\"post\" name=\"toPageForm\" action=\""+toPageFormUrl+"\"    target=\"_blank\">";
	        	
exportInfoFormHtml+="<input type=\"hidden\"  name=\"exportInfoData\" id=\"exportInfoData\" value=\""+encodeURIComponent(encodeURIComponent(JSON.stringify(data),"UTF-8"),"UTF-8")+"\"/>";
exportInfoFormHtml+="</form>";
	        		
$('#cirInfoExportInfoPage').html(exportInfoFormHtml);
$("#toPageForm").submit();

A.jsp页面：接收参数对应解码：decodeURIComponent(decodeURIComponent(_exportInfoData,"UTF-8"),"UTF-8")

然后 str 转 json :_exportInfoData =JSON.parse(_exportInfoData);

<%String exportInfoData = request.getParameter("exportInfoData")==null?"":request.getParameter("exportInfoData").toString();%>

<script>

var _exportInfoData="<%=exportInfoData%>";
_exportInfoData = decodeURIComponent(decodeURIComponent(_exportInfoData,"UTF-8"),"UTF-8");
_exportInfoData =JSON.parse(_exportInfoData);
</script>
