I used $.ajax() to consume a local .asmx webservice. Here’s my code for the call:

    $("#btnGetOne").click(function() {
        $.ajax({
            type: 'POST',
            contentType: 'application/json; charset=utf-8',
            url: 'http://localhost:53003/TestWebService.asmx/GetServant',
            data: '{ "servant_id": "' + $("#txtServantID").val() + '" }',
            dataType: 'json',
            success: function(data, textStatus, jqXHR) {
                var jsnData = $.parseJSON(data.d);
                $('#DisplayArea').html(jsnData.Servant_Name);
            },
            error: function(jqXHR, textStatus, errorThrown) {
                alert(textStatus + ' ' + errorThrown);
            }
        });
    });

As you can see the ajax call executes when I click btnGetOne.

As in my question header, this works in jquery-1.4.1, but when I used jquery-1.6.2 I get an errorThrown saying No Transport.

Is there anything else I’m missing?

    Your HTML+JS page is probably not loaded from localhost:53003, while you are trying to, using Ajax, an URL that is on domain localhost:53003.

    So, it looks like you are trying to make a cross-domain request, which is forbidden — see Same Origin Policy.

    Taking a look a the documentation of jQuery.support, you might want to enable jQuery.support.cors (quoting) :

    cors is equal to true if a browser can create an XMLHttpRequest
    object and if that XMLHttpRequest object has a withCredentials
    property.

    To enable cross-domain requests in environments
    that do not support cors yet but do allow cross-domain XHR requests
    (windows gadget, etc), set $.support.cors = true;.

    And here are a couple of links that might help :
