1. 在Asp.net实用技巧（1） 中提到了如何刷新父页面，那么如果要刷新父页面的父页面的父页面了？那就是刷新祖先页面RefreshAncestorPage。
RefreshAncestorPage#region RefreshAncestorPage
/**//// <summary>
/// 刷新指定的祖先页面，注意是"祖先页面" 
/// </summary> public static void RefreshAncestorPage(HttpResponse Response ,string targetPageTitle ,bool isCloseCurPage)//targetPageTitle 目标页面的title 
{ StringBuilder scriptString = new StringBuilder(); scriptString.Append("<script language = javascript>"); scriptString.Append("var p = window ;"); scriptString.Append(string.Format("while(p.document.title != '{0}')" ,targetPageTitle)); scriptString.Append("{"); scriptString.Append("p = p.opener ;"); scriptString.Append("}"); scriptString.Append("p.focus();"); scriptString.Append("p.refresh();"); if (isCloseCurPage ) { scriptString.Append( " window.focus();" ); scriptString.Append( " window.opener=null;" ); scriptString.Append( " window.close(); " ); } scriptString.Append("</"+"script>"); Response.Write(scriptString.ToString()); } /**//* 需要在Father页面的html中添加如下脚本（在Header中）： <script language="javascript"> function refresh() { this.location = this.location; } </script> */ 
#endregion2.如何刷新祖先页面中的某个frame中的page了？
RefreshFrameInAncestorPage#region RefreshFrameInAncestorPage /**//// <summary> /// 刷新指定的祖先页面中的某个框架的内部页面 /// </summary> public static void RefreshFrameInAncestorPage(HttpResponse Response ,string ancestorTitle ,string frameName ,string targetUrl ,bool isCloseCurPage)//targetPageTitle 目标页面的title { StringBuilder scriptString = new StringBuilder(); scriptString.Append("<script language = javascript>"); scriptString.Append("var p = window ;"); scriptString.Append(string.Format("while(p.document.title != '{0}')" ,ancestorTitle)); scriptString.Append("{"); scriptString.Append("p = p.opener ;"); scriptString.Append("}"); scriptString.Append("p.focus();"); scriptString.Append(string.Format("p.{0}.location = '{1}';" ,frameName, targetUrl)); if (isCloseCurPage ) { scriptString.Append( " window.focus();" ); scriptString.Append( " window.opener=null;" ); scriptString.Append( " window.close(); " ); } scriptString.Append("</"+"script>"); Response.Write(scriptString.ToString()); } #endregion3.如何刷新本页面中的其它框架了？
RefreshTargetFrameInSamePage#region RefreshTargetFrameInSamePage /**//// <summary> /// 从某一框架刷新同一页面中的任意一框架（包括自己所处的框架） /// </summary> public static void RefreshTargetFrameInSamePage(HttpResponse Response ,string frameName ,string targetUrl) { string scripStr = string.Format("<script language ='javascript'> window.parent.{0}.location= '" ,frameName) +targetUrl + "'"; scripStr += "</"+"script>" ; Response.Write(scripStr) ; } #endregion 4.如何调用祖先页面的脚本？
CallAncestorScriptMethod#region CallAncestorScriptMethod /**//// <summary> /// 调用祖先页面中的某个框架内部page的脚本 ，如果是调用祖先页面的脚本，targetFrameName传入null /// </summary> public static void CallAncestorScriptMethod(HttpResponse Response ,string targetPageTitle ,string targetFrameName ,string methodName ,string[] paraStrs) { StringBuilder scriptString = new StringBuilder(); scriptString.Append("<script language = javascript>"); scriptString.Append("var p = window ;"); scriptString.Append(string.Format("while(p.document.title != '{0}')" ,targetPageTitle)); scriptString.Append("{"); scriptString.Append("p = p.opener ;"); scriptString.Append("}"); if(targetFrameName != null) { if(paraStrs == null) { scriptString.Append(string.Format("p.frames['{0}'].{1}() ;" ,targetFrameName ,methodName )); } else { string rParaStr = string.Format("'{0}'" ,paraStrs[0]) ; for(int i=1 ;i<paraStrs.Length ;i++) { rParaStr += string.Format(", '{0}'" ,paraStrs[i]) ; } scriptString.Append(string.Format("p.frames['{0}'].{1}({2}) ;" ,targetFrameName ,methodName ,rParaStr)); } } else { if(paraStrs == null) { scriptString.Append(string.Format("p.{0}() ;" ,methodName )); } else { string rParaStr = string.Format("'{0}'" ,paraStrs[0]) ; for(int i=1 ;i<paraStrs.Length ;i++) { rParaStr += string.Format(", '{0}'" ,paraStrs[i]) ; } scriptString.Append(string.Format("p.{0}({1}) ;" ,methodName ,rParaStr)); } } scriptString.Append("</"+"script>"); Response.Write(scriptString.ToString()); } #endregion
5.如何调用本页面中其它框架page的脚本？
CallTargetFrameScriptMethodInSamePage#region CallTargetFrameScriptMethodInSamePage /**//// <summary> /// 调用本页面中其它框架内部page的脚本 ， /// </summary> public static void CallTargetFrameScriptMethodInSamePage(HttpResponse Response ,string targetFrameName ,string methodName ,string[] paraStrs) { StringBuilder scriptString = new StringBuilder(); scriptString.Append("<script language = javascript>"); if(paraStrs == null) { scriptString.Append(string.Format("window.parent.{0}.{1}() ; ;" ,targetFrameName ,methodName)); } else { string rParaStr = string.Format("'{0}'" ,paraStrs[0]) ; for(int i=1 ;i<paraStrs.Length ;i++) { rParaStr += string.Format(", '{0}'" ,paraStrs[i]) ; } scriptString.Append(string.Format("window.parent.{0}.{1}({2}) ; ;" ,targetFrameName ,methodName ,rParaStr)); } scriptString.Append("</"+"script>"); Response.Write(scriptString.ToString()); } #endregion可见上述这些功能都是通过脚本完成的，如果对脚本不熟悉，是不可能做好Web开发的！
