如何从javascript调用Web服务方法？

Is there any way to call web services from javascript? I know you can add in a script manager to pull in the web services but I can't figure out how to access the functions from javascript once I've done that.

有没有办法从JavaScript调用Web服务？我知道你可以添加一个脚本管理器来引入Web服务，但是一旦我完成了，我就无法弄清楚如何从javascript访问这些函数。

Thanks,
Matt

Please see Calling Web Services from Client Script in ASP.NET AJAX:

请参阅ASP.NET AJAX中从客户端脚本调用Web服务：

This topic explains how to use to call a Web service from ECMAScript (JavaScript). To enable your application to call ASP.NET AJAX Web services by using client script, the server asynchronous communication layer automatically generates JavaScript proxy classes. A proxy class is generated for each Web service for which an <asp:ServiceReference> element is included under the <asp:ScriptManager> control in the page.

本主题说明如何使用ECMAScript（JavaScript）调用Web服务。为了使您的应用程序能够使用客户端脚本调用ASP.NET AJAX Web服务，服务器异步通信层会自动生成JavaScript代理类。为每个Web服务生成一个代理类，其中元素包含在页面中的控件下。：scriptmanager> ：servicereference>

  $.ajax({
    type: "POST",
    url: "RSSReader.asmx/GetRSSReader",
    data: "{}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
      // Hide the fake progress indicator graphic.
      $('#RSSContent').removeClass('loading');

      // Insert the returned HTML into the <div>.
      $('#RSSContent').html(msg.d);
    }
  });
