在JSP页面中设置隐藏表单：
<input type="hidden" id="monthDate" value="<%=monthDate%>">
然后在JS文件中获取monthDate，并调用Service中的exportExcel方法：
var downLoadExcel = function(){
var inInfo = new EiInfo();
inInfo.set("monthDate",$("#monthDate").val());
EiCommunicator.send("FKRY0001","exportExcel", inInfo,null);
window.open("./FK/common/download.jsp?docname=test.xls");
}
