Getting error using json

Dec 09, 2010 05:24 PM|LINK

I am trying to call webservice method using JSON.

my code is as follows

<script src="jquery-1.3.2.min.js" type ="text/javascript" ></script>
    <script type ="text/javascript" >
    var pageUrl = '<%=ResolveUrl("~/CS.aspx")%>'
function PopulateContinents() {
    $("#<%=ddlCountries.ClientID%>").attr("disabled", "disabled");
    $("#<%=ddlCities.ClientID%>").attr("disabled", "disabled");
    if ($('#<%=ddlContinents.ClientID%>').val() == "0") {
        $('#<%=ddlCountries.ClientID %>').empty().append('<option selected="selected" value="0">Please select</option>');
        $('#<%=ddlCities.ClientID %>').empty().append('<option selected="selected" value="0">Please select</option>');
    }
    else {
        $('#<%=ddlCountries.ClientID %>').empty().append('<option selected="selected" value="0">Loading...</option>');
        $.ajax({
            type: "POST",
            url: "CS.aspx.cs/PopulateCountries",
            data: "()" ,
            contentType: "application/json; charset=utf-8",
            timeout: 10000,
            dataType: "json",
            success: OnCountriesPopulated,
            error: function(xhr) {if (!error) return;
                                    if (xhr.responseText)
                                    {var err = JSON2.parse(xhr.responseText);
                                                                if (err)error(err);
                                                                else error( { Message: "Unknown server error." })} return;},
            failure: function(response) {
                alert(response.d);
            }
        });
    }
}

But am getting error like this:

<html>
    <head>
        <title>This type of page is not served.</title>
        <style>
         body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} 
         p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px}
         b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px}
         H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red }
         H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon }
         pre {font-family:"Lucida Console";font-size: .9em}
         .marker {font-weight: bold; color: black;text-decoration: none;}
         .version {color: gray;}
         .error {margin-bottom: 10px;}
         .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }
        </style>
    </head>

    <body bgcolor="white">

            <span><H1>Server Error in '/' Application.<hr width=100% size=1 color=silver></H1>

            <h2> <i>This type of page is not served.</i> </h2></span>

You did not use your pageUrl variable. You've set the url to "CS.aspx.cs". You can't serve a .cs file. Only an aspx page.

Also an aspx page isn't really a webservice.

url: "CS.aspx.cs/PopulateCountries",

The URL cannot have ".cs" in the end. ".cs" pages are only for the server and are never served. You have to change it to just ".aspx" or ".asmx" (for web services).

Also, the web service should have [ScriptService] attribute.

Thanks.
