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，是不可能做好的！
