ajax call HELPPP

Hi there,

The following code is a very simple ajax call to server that alerts back on success and complete events.

From a reason I cannot understand on my development machine it works fins and alerts on success and complete but on server it never alerts on success. WHY ???

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>

    <script src="Scripts/jquery-1.7.1.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        function dummy() {
            $.ajax({
                url: 'services/chatEngine.asmx/dummy',
                async: true,
                type: "POST",
                complete: function () { alert('Done'); },
                success: function (a, b, c) {
                    alert('Success');
                }
            });
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
        </ajaxToolkit:ToolkitScriptManager>
        <div id="userList">Users:<br /></div>

        <input id="Button3" type="button" value="dummy" onclick="dummy()" />
    </div>
    </form>
</body>
</html>

The server side dummy function returns nothing, code follows -

<WebMethod(True)>
Public Function dummy() As String
    Return ""
End Function

Re: ajax call HELPPP

I suspect that when the deployed the url is wrong. You can use a tool like fiddler to monitor where the ajax call is going.

Re: ajax call HELPPP

function CallService() { var name = $("#taYourName").text();

//Also check whether you're getting the name before you call the webservice

// alert(name) $.ajax( { Type: "POST", contentType: "application/json; charset=utf-8", url: "YourNameIs.asmx/YourName", data: "{ 'yourName': '"+name+"' }", success: function (msg) { $("#lblForAjax").text(msg.d); } });

Check below url's you'll have idea..

Re: ajax call HELPPP

The solution for this headache follows -

Instead of: url: 'services/chatEngine.asmx/dummy',

I used: url: 'services/chatEngine.asmx?op=dummy',

Thanks for everyone
