开发者_如何学C <script language="javascript">
$(document).ready(function() {
$("#txtNoOfMales").change(function() {
var ticketRequired = this.value;
var options = {
type: "POST",
url: "CallServerWithParameters.aspx/GetAvailableTicketsForMales",
data: "{no:" + ticketRequired + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(response) {
if (response.d != "") {
alert(response.d);
$("#txtNoOfMales").focus();
}
}
};
//Call the PageMethods
$.ajax(options);
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
No of Male Tickets:<asp:TextBox ID="txtNoOfMales" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
and the following web method on the server side
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
public partial class CallServerWithParameters : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static string GetAvailableTicketsForMales(int no)
{
string result = "";
int NoOfTicketsAvailable = 5;
if (no > NoOfTicketsAvailable)
{
result = "Only " + NoOfTicketsAvailable.ToString() + " Male ticket(s) avaialable. Please eneter a lower number!";
}
return result;
}
}
problem is everything works fine on .net 3.5 but if i use the same code on .net 2.0 the webmethod event does not get call at all, anybody have any idea what i did wrong?
thanks
updated with full source code
It works for my declaring the web method with the following attributes:
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
Also I use PageMethods.GetAvailableTicketsForMales to call the function from js.
I hope this will help you.
