　　下面的文章將介紹：

　　how Microsoft “Atlas” helps web developers make network callbacks directly from client-side script code.

　　本文將學習以下內容：

how to create a simple web service that is “Atlas” enabled;
how to call this web service from client-side JavaScript code;
how to use the data returned from the web service.

　　詳細步驟：

1、先見一個簡單的web service，只將HelloWorld方法小改如下：

　[WebMethod]
    public string HelloWorld(String ss)
    {
        return "Hello " + ss;
    }

2、在“源”頁面裡，把代碼“<atlas:ScriptManager ID="ScriptManager1" runat="server" / >”修改成如下代碼：

<atlas:ScriptManager ID="ScriptManager1" runat="server" >
            <Services>
                <atlas:ServiceReference Path="WebService.asmx" />
            </Services>
        </atlas:ScriptManager>

3、在“設計”頁面裡從“ HTML ” 選項卡裡拖拽一個“text”和“button”控制項，雙擊“button”控制項，切換到“源”頁面，把代碼“function Button1_onclick() { }”修改成如下代碼：

function Button1_onclick()
{
abc = WebService.HelloWorld(document.getElementById('Text1').value,OnComplete,OnTimeOut);
return false;
}

function OnComplete(result)
{
alert(result);
}

function OnTimeOut(result)
{
alert("逾時！");
}

4、儲存所有檔案，　F5運行一把，在“text”裡輸入任一字元，點擊按鈕，檢驗一下效果。

完整代碼：

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
<script language="javascript" type="text/javascript">...
// <!CDATA[

function Button1_onclick()
...{
    abc = WebService.HelloWorld(document.getElementById('Text1').value,OnComplete,OnTimeOut);
    return false;
}

function OnComplete(result)
...{
    alert(result);
}

function OnTimeOut(result)
...{
    alert("逾時！");
}

// ]]>
</script>
</head>
<body>
    <form id="form1" runat="server">
        <atlas:ScriptManager ID="ScriptManager1" runat="server" >
        <Services>
        <atlas:ServiceReference  Path="WebService.asmx" />

        </Services>
        </atlas:ScriptManager>
        <br />
        請輸入你的姓名：
        <input id="Text1" type="text" />
        <input id="Button1" type="button" value="button" onclick="return Button1_onclick()" /></form>
</body>
</html>
