ASP.NET AJAX ScriptManager调用WebService
ScriptManager是一个ASP.NET AJAX中的核心控件。它为ASP.NET AJAX开发的带了很多的便利，它是我们做ASP.NET AJAX的程序不可缺少的控件，它的作用非比寻常，我们来看看他是如何调用WebService的！
首先建立一个MyWebService.asmx文件。（一定注意看中文注释）
以下为MyWebService.cs代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
/// <summary>
/// Summary description for MyWebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
//下面这行属性是用ScriptManager调用WebService的必要属性。
[System.Web.Script.Services.ScriptService]
public class MyWebService : System.Web.Services.WebService
{
public MyWebService()
{
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public int GetTotal(int x, int y)
{
return x + y;
}
}
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
/// <summary>
/// Summary description for MyWebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
//下面这行属性是用ScriptManager调用WebService的必要属性。
[System.Web.Script.Services.ScriptService]
public class MyWebService : System.Web.Services.WebService
{
public MyWebService()
{
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public int GetTotal(int x, int y)
{
return x + y;
}
}
在Default.aspx页面中添加ScriptManager控件并引用WebService

</asp:ScriptManager>
<script type="text/javascript">
MyWebService.GetTotal(5, 4, ShowResult, null, "abc");
</script>
</div>
</form>
</body>
</html>

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

</asp:ScriptManager>
<script type="text/javascript">
MyWebService.GetTotal(5, 4, ShowResult, null, "abc");
</script>
</div>
</form>
</body>
</html>
但我们在ScriptManager中引用了WebService就可以在JS脚本里面调用WebService了。
GetTotal是在WebService中对应的WebService方法，但在这里它多了3个参数。
GetTotal(number x,number y,onSuccess,onError,userContent);
大家看看这个参数名就应该知道是什么意思了吧！！
其实用ScriptManager调用WebService很简单的！
有任何问题可以给我留言！
