JavaScript的：Alert.Show（消息）从ASP.NET code-背后

问题描述

我读这个<一个href=\"http://archive.devnewz.com/devnewz-3-20061129JavaScriptAlertShowmessagefromASPNET$c$cbehind.html\">JavaScript: Alert.Show（消息）从ASP.NET code-背后

我想实现相同。所以，我创建了一个静态类是这样的：

I am trying to implement the same. So I created a static class like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Data.SqlClient;
using System.Web;
using System.Text;
using System.Web.UI;

namespace Registration.DataAccess
{
    public static class Repository
    {
        /// <summary> 
        /// Shows a client-side JavaScript alert in the browser. 
        /// </summary> 
        /// <param name="message">The message to appear in the alert.</param> 
        public static void Show(string message) 
            { 
               // Cleans the message to allow single quotation marks 
               string cleanMessage = message.Replace("'", "\'"); 
               string script = "<script type="text/javascript">alert('" + cleanMessage + "');</script>"; 

               // Gets the executing web page 
               Page page = HttpContext.Current.CurrentHandler as Page; 

               // Checks if the handler is a Page and that the script isn't allready on the Page 
               if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert")) 
               { 
                 page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); 
               } 
            } 
    }
}

在这一行：

string script = "<script type="text/javascript">alert('" + cleanMessage + "');</script>"; 

这是显示我的错误：;预计

和也

page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); 

错误：类型或命名空间名称'警报'找不到（是否缺少using指令或程序集引用）

我在做什么错在这里？

What I am doing wrong here?

推荐答案

下面是一个简单的方法：

Here is an easy way:

Response.Write("<script>alert('Hello');</script>");
