【转】ASP.NET AJAX入门系列（8）：使用ScriptManager控件

看一个简单的调用WebService的例子：

WebService如下，注意在WebServiceSample上加ScriptService特性：页面：

[ScriptService]

public class WebServiceSample : System.Web.Services.WebService {

    public WebServiceSample()

    {

        //Uncomment the following line if using designed components 

        //InitializeComponent(); 

    }


    [WebMethod]

    public string EchoString(String s)

    {
        return "Hello " + s;
    }

}

ASPX

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Untitled Page</title>

</head>

<script type="text/javascript" language="JavaScript">

    function OnbuttonGo_click() 

    {
        requestSimpleService = WebServiceSample.EchoString(

            document.getElementById('inputName').value,       //params

            OnRequestComplete    //Complete event

            );

        return false;
    }

    function OnRequestComplete(result) 

    {
        alert(result);
    }

</script>

<body>

    <form id="form1" runat="server">

    <asp:ScriptManager ID="ScriptManager1" runat="server">

        <Services>

            <asp:ServiceReference Path="WebServiceSample.asmx"/>

        </Services>

    </asp:ScriptManager>

    <div>

        <input type="text" id="inputName" size=20/>

        <input id="button" type="button" value="调 用" onclick="return OnbuttonGo_click()" /></div>

    </form>

</body>

</html>
