1. 在Asp.net實用技巧（1） 中提到了如何重新整理父頁面，那麼如果要重新整理父頁面的父頁面的父頁面了？那就是重新整理祖先頁面RefreshAncestorPage。
RefreshAncestorPage#region RefreshAncestorPage
/**//// <summary>
/// 重新整理指定的祖先頁面，注意是"祖先頁面"
/// </summary>
public static void RefreshAncestorPage(HttpResponse Response ,string targetPageTitle ,bool isCloseCurPage)//targetPageTitle 目標頁面的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頁面的html中添加如下指令碼（在Header中）：
<script language="javascript">
function refresh()
{
this.location = this.location;
}
</script>
*/
#endregion
2.如何重新整理祖先頁面中的某個frame中的page了？
RefreshFrameInAncestorPage#region RefreshFrameInAncestorPage
/**//// <summary>
/// 重新整理指定的祖先頁面中的某個架構的內部頁面
/// </summary>
public static void RefreshFrameInAncestorPage(HttpResponse Response ,string ancestorTitle ,string frameName ,string targetUrl ,bool isCloseCurPage)//targetPageTitle 目標頁面的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());
}
#endregion
3.如何重新整理本頁面中的其它架構了？
RefreshTargetFrameInSamePage#region RefreshTargetFrameInSamePage
/**//// <summary>
/// 從某一架構重新整理同一頁面中的任意一架構（包括自己所處的架構）
/// </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.如何調用祖先頁面的指令碼？
CallAncestorScriptMethod#region CallAncestorScriptMethod
/**//// <summary>
/// 調用祖先頁面中的某個架構內部page的指令碼 ，如果是調用祖先頁面的指令碼，targetFrameName傳入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.如何調用本頁面中其它架構page的指令碼？
CallTargetFrameScriptMethodInSamePage#region CallTargetFrameScriptMethodInSamePage
/**//// <summary>
/// 調用本頁面中其它架構內部page的指令碼 ，
/// </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
可見上述這些功能都是通過指令碼完成的，如果對指令碼不熟悉，是不可能做好Web開發的！
