我試圖在由C#生成的Web服務器上執行一個簡單的Javascript方法。我可以讓Web服務器運行並使用按鈕生成一個簡單的網頁,但我似乎無法獲得運行js的按鈕。使用c在Web服務器上運行JavaScript方法#
Using System;
using System.Net;
using System.Threading;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Web.UI.HtmlControls;
//using System.Web.UI.Page;
namespace SimpleWebServer
{
class Program
{
static void Main(string[] args)
{
WebServer ws = new WebServer(SendResponse, "http://localhost:8080/test/");
// ClientScript.RegisterStartupScript(page.GetType(), "hwa", "alert('Hello World');", true);
Console.WriteLine("A simple webserver. Press a key to quit.");
Console.ReadKey();
ws.Stop();
}
public static string SendResponse(HttpListenerRequest request)
{
ws = WebServer;
//return string.Format("<HTML><HEAD><script src='D:/Script1.js'></script></HEAD><BODY><INPUT type='button' value='Button' runat='server' id='Button1' onClick='buttonClicked()';></BODY></HTML>)");
ClientScript.RegisterStartupScript(page.GetType(), "hwa", "alert('Hello World');", true);
return string.Format("<HTML><HEAD><script= alert('button click called');</HEAD><BODY><INPUT type='button' value='Button' runat='server' id='Button1' onClick='alert('button click called')';></BODY></HTML>)");
JS腳本代碼如下:
function buttonClicked() {
alert('button click called');
}
Web服務器的代碼如下:
using System;
using System.Net;
using System.Threading;
using System.Linq;
using System.Text;
namespace SimpleWebServer
{
public class WebServer
{
private readonly HttpListener _listener = new HttpListener();
private readonly Func<HttpListenerRequest, string> _responderMethod;
public WebServer(string[] prefixes, Func<HttpListenerRequest, string> method)
{
if (!HttpListener.IsSupported)
throw new NotSupportedException(
"Needs Windows XP SP2, Server 2003 or later.");
// URI prefixes are required, for example
// "http://localhost:8080/index/".
if (prefixes == null || prefixes.Length == 0)
throw new ArgumentException("prefixes");
// A responder method is required
if (method == null)
throw new ArgumentException("method");
foreach (string s in prefixes)
_listener.Prefixes.Add(s);
_responderMethod = method;
_listener.Start();
}
public WebServer(Func<HttpListenerRequest, string> method, params string[] prefixes)
: this(prefixes, method) { }
// protected void Button1_Click(Object sender, EventArgs e)
// {
// Button1.Text = "Server click handler called.";
// }
public void Run()
{
ThreadPool.QueueUserWorkItem((o) =>
{
Console.WriteLine("Webserver running...");
try
{
while (_listener.IsListening)
{
ThreadPool.QueueUserWorkItem((c) =>
{
var ctx = c as HttpListenerContext;
try
{
string rstr = _responderMethod(ctx.Request);
byte[] buf = Encoding.UTF8.GetBytes(rstr);
ctx.Response.ContentLength64 = buf.Length;
ctx.Response.OutputStream.Write(buf, 0, buf.Length);
}
catch { } // suppress any exceptions
finally
{
// always close the stream
ctx.Response.OutputStream.Close();
}
}, _listener.GetContext());
}
}
catch { } // suppress any exceptions
});
}
public void Stop()
{
_listener.Stop();
_listener.Close();
}
}
}
我發現的最有用的建議是在這裏:[鏈接] http://stackoverflow.com/questions/5731224/calling-javascript-function-from-codebehind [/ link] 我不確定這裏的規則的細節,但我已經盡力實施它,但對任何一種語言的知識都有限我被卡住了 – 2015-03-30 23:08:14
你有一個第一行中的拼寫錯誤,使用應該是小寫使用。不知道它會幫助雖然.. – torox 2015-03-30 23:11:26
