Asp.net实用技巧（2）

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！
