关于showmodaldialog 打开新窗口后提交表单操作时，避免弹出新窗口和避免从后台获取“新数据”后不能刷新当前模态页面的解决方案

案例：从父页面A 通过showmodaldialog的方式 打开模态子页面B,子页面上进行“查询，翻页功能”

1：从父页面A打开子页面B：

var url = "cn.ccb.orms.rcsa.pageflow.RscaQueryItemInfosPopup.flow"; 
var itemInfo = showModalDialog(url,window,'dialogWidth:800px;dialogHeight:500px;dialogLeft:100px;dialogTop:250px;center:yes;help:yes;resizable:yes;status:yes'); 

 

2：进入模态页面B后的JS和JAVA代码
