Calling a Static Page Method using jQuery

By -
If you do not plan to call a web method from multiple pages, don’t perform all the work of creating a separate web service. Instead, you can expose a static method from the same AJAX page calling the web method.

1..ASPX Page -



DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title>Show Web Service Methodtitle>
    <script type="text/javascript" src="../Scripts/jquery-1.4.1.js">script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#btnGet").click(function () {
                $.ajax({
                    type: "POST",
                    dataType: "json",
                    contentType: "application/json",
                    url: "ShowPageMethod.aspx/GetQuote",
                    success: function (data) {
                        $("#spanQuote").html(data.d);
                    },
                    error: function () {
                        alert("The call to the web service failed.");
                    }
                })
            });
        });
    script>
head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="btnGet" type="button" value="Get Quote" />
        <br />
        <br />
        <span id="spanQuote">span>
    div>
    form>
body>
html>


2. Code Behind Code (.ASPX.CS)

 Add this method
 
        [System.Web.Services.WebMethod]
        public static string GetQuote()
        {
            List<string> quotes = new List<string>();
            quotes.Add("The fool who is silent passes for wise.");
            quotes.Add("The early bird catches the worm.");
            quotes.Add("If wishes were true, shepherds would be kings.");
            Random rnd = new Random();
            return quotes[rnd.Next(quotes.Count)];
        }
