ASP.NET中使用各种窗口的代码

警告窗口

----------------------------------------------------------------------------------------------------------------------

/// <summary>

/// 服务器端弹出alert对话框

/// </summary>

/// <param name="str_Message">提示信息,例子："不能为空!"</param>

/// <param name="page">Page类</param>

public void Alert(string str_Message,Page page)

   {

   page.RegisterStartupScript("","<script>alert('"+str_Message+"');</script>");

}

重载此警告窗口,使某控件获得焦点

----------------------------------------------------------------------------------------------------------------------

/// <summary>

/// 服务器端弹出alert对话框，并使控件获得焦点

/// </summary>

/// <param name="str_Ctl_Name">获得焦点控件Id值,比如：txt_Name</param>

/// <param name="str_Message">提示信息,例子："请输入您姓名!"</param>

/// <param name="page">Page类</param>

public void Alert(string str_Ctl_Name,string str_Message,Page page)

   {

   page.RegisterStartupScript("","<script>alert('"+str_Message+"');document.forms(0)."+str_Ctl_Name+".focus(); document.forms(0)."+str_Ctl_Name+".select();</script>");

}

确认对话框

----------------------------------------------------------------------------------------------------------------------

/// <summary>

/// 服务器端弹出confirm对话框

/// </summary>

/// <param name="str_Message">提示信息,例子："您是否确认删除!"</param>

/// <param name="btn">隐藏Botton按钮Id值,比如：btn_Flow</param>

/// <param name="page">Page类</param>

public void Confirm(string str_Message,string btn,Page page)

   {

   page.RegisterStartupScript("","<script> if (confirm('"+str_Message+"')==true){document.forms(0)."+btn+".click();}</script>");

}

重载确认对话框，点击确定触发一个隐藏按钮事件，点击取消触发一个隐藏按钮事件

----------------------------------------------------------------------------------------------------------------------

/// <summary>

/// 服务器端弹出confirm对话框,询问用户准备转向那些操作，包括“确定”和“取消”时的操作

/// </summary>

/// <param name="str_Message">提示信息，比如："成功增加数据,单击/"确定/"按钮填写流程,单击/"取消/"修改数据"</param>

/// <param name="btn_Redirect_Flow">"确定"按钮id值</param>

/// <param name="btn_Redirect_Self">"取消"按钮id值</param>

/// <param name="page">Page类</param>

public void Confirm(string str_Message,string btn_Redirect_Flow,string btn_Redirect_Self,Page page)

   {

   page.RegisterStartupScript("","<script> if (confirm('"+str_Message+"')==true){document.forms(0)."+btn_Redirect_Flow+".click();}else{document.forms(0)."+btn_Redirect_Self+".click();}</script>");

}

获得焦点

----------------------------------------------------------------------------------------------------------------------

/// <summary>

/// 使控件获得焦点

/// </summary>

/// <param name="str_Ctl_Name">获得焦点控件Id值,比如：txt_Name</param>

/// <param name="page">Page类</param>

public void GetFocus(string str_Ctl_Name,Page page)

   {

   page.RegisterStartupScript("","<script>document.forms(0)."+str_Ctl_Name+".focus(); document.forms(0)."+str_Ctl_Name+".select();</script>");

}

子窗体返回主窗体

----------------------------------------------------------------------------------------------------------------------

   ///<summary>

///名称：redirect

///功能：子窗体返回主窗体

///参数：url

///返回值：空

///</summary>

public void redirect(string url,Page page)

   {

   if ( Session["IfDefault"]!=(object)"Default")

    {    

    page.RegisterStartupScript("","<script>window.top.document.location.href='"+url+"';</script>");

   }

}

返回上一页并刷新

------------------------------------------------------------------------------------------------------------------

<script Language="JavaScript">

   alert("修改成功!");

   history.go(-2);

   location.reload();

</script>

如果返回上一页最好的方法我觉得是这个

<script Language="JavaScript">

   alert("删除成功!");

   window.location.href=document.referrer;

</script>
