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()
{
&[1] [2] [3] [4] [5] [6] 下一页 |
