关于AJAX应用于web网页，如何弹出对话框的几种常用方法【用的时候直接调用即可】

/// <summary>显示消息提示对话框

    /// 显示消息提示对话框

    /// </summary>

    /// <param name="page">当前页面指针，一般为this</param>

    /// <param name="msg">提示信息</param>

    public  void Show(System.Web.UI.Page page, string msg)

    {     

        

        //page.RegisterStartupScript("message", "<script language='javascript' defer>alert('" + msg.ToString() + "');</script>");

        page.ClientScript.RegisterStartupScript(page.GetType(), "message", "<script language='javascript' defer>alert('" + msg.ToString() + "');</script>");

    }

    

    /// <summary>

    /// 控件点击消息确认提示框

    /// </summary>

    /// <param name="page">当前页面指针，一般为this</param>

    /// <param name="msg">提示信息</param>

    public  void ShowConfirm(System.Web.UI.WebControls.WebControl Control, string msg)

    {

        Control.Attributes.Add("onclick", "return confirm('" + msg + "');");

    }

    /// <summary>

    /// 显示消息提示对话框，并进行页面跳转

    /// </summary>

    /// <param name="page">当前页面指针，一般为this</param>

    /// <param name="msg">提示信息</param>

    /// <param name="url">跳转的目标URL</param>

    public  void ShowAndRedirect(System.Web.UI.Page page, string msg, string url)

    {

        StringBuilder Builder = new StringBuilder();

        Builder.Append("<script language='javascript' defer>");

        Builder.AppendFormat("alert('{0}');", msg);

        Builder.AppendFormat("top.location.href='{0}'", url);

        Builder.Append("</script>");

       // page.RegisterStartupScript("message", Builder.ToString());

        page.ClientScript.RegisterStartupScript(page.GetType(), "message", Builder.ToString());

    }

   /// <summary>

   /// Ajax弹出对话框

   /// </summary>

   /// <param name="control">一般为UpdataPanle</param>

   /// <param name="type">this.Gettype()</param>

   /// <param name="script">提示信息</param>

    public void AjaxResponeSrcipt(System.Web.UI.Control control, Type type, string script)

    {

        ScriptManager.RegisterClientScriptBlock(control, type, "click", "alert('"+script+"')", true);
    }

【实例应用：】

msgBox.AjaxResponeSrcipt(UpdatePanel1, this.GetType(), "请输入正确的信息！");


    /// <summary>

    /// Ajax跳转页面

    /// </summary>

    /// <param name="control">一般为UpdataPanle</param>

    /// <param name="type">this.Gettype()</param>

    /// <param name="script">js脚本</param>

    public void AjaxTiaoZhuan(System.Web.UI.Control control, Type type, string script)

    {

        ScriptManager.RegisterStartupScript(control,type, "alert", script, true);

    }

    public void AjaxResponeSrciptAndBack(System.Web.UI.Control control, Type type, string script)

    {

        ScriptManager.RegisterClientScriptBlock(control, type, "click", "alert('" + script + "');history.go(-1);", true);

    }

    public void AjaxResponeSrciptAndClose(System.Web.UI.Control control, Type type, string script)

    {

        ScriptManager.RegisterClientScriptBlock(control, type, "click", "alert('" + script + "');window.close();", true);

    }
