What do you mean by "alert box from web method"? Alert box in on the client side, and the method is executed on the server side. Maybe, out of the method result returned? Then what's the problem?

Aspx code here :

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script src="js/jquery-1.9.0.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $("#btnCall").click(function () {
            alert("eded"); 
            $.ajax({
            type: "POST",
            url: "Default.aspx/DoSomething",
            data: "{}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                alert(msg.d);
            }
        });
        }); 
    });

</script>

    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <button id="btnCall" type="button">Call Method</button>
    </div>
    </form>
</body>
</html></html>

Do what ever you want in the method success
code behind content:

C#

using System;
using System.Web.Services;
using System.Web.Script.Services;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    [WebMethod]
    [ScriptMethod]
    public static string DoSomething()
    {
        return "sba";
    }

}
