Question

I have reviewed a lot of answers to this type of question and now I am confused as to the best way. Given the latest jquery, I am wanting to

1. Call an ajax funct

Answer 1

As previously mentioned, using Callbacks.

function process(url, params, successCallback, errorCallback) {
    $.ajax({
        success : successCallback,
        error : errorCallback,
        data : params,
        url : url,
        type : 'POST',
        dataType : 'json'
    });
}

process(
    'http://www.google.co.uk', 
    { 
        param1 : 'a' 
    }, 
    function(resp) { 
        alert('Success');
    },
    function() {
        alert('Uh oh');
    }
);

You can then pass any function to process and it will be called on success/error.
