How to call .ajaxStart() on specific ajax calls

Question

I have some ajax calls on the document of a site that display or hide a progress bar depending on the ajax status

  $(document).ajaxStart(function(){ 
        $('#ajaxProgress').show(); 
    });
  $(document).ajaxStop(function(){ 
        $('#ajaxProgress').hide(); 
    });

I would like to basically overwirte these methods on other parts of the site where a lot of quick small ajax calls are made and do not need the progress bar popping in and out. I am trying to attach them to or insert them in other $.getJSON and $.ajax calls. I have tried chaining them but apparently that is no good.

$.getJSON().ajaxStart(function(){ 'kill preloader'});

You can bind the ajaxStart and ajaxStop using custom namespace:

$(document).bind("ajaxStart.mine", function() {
    $('#ajaxProgress').show();
});

$(document).bind("ajaxStop.mine", function() {
    $('#ajaxProgress').hide();
});

Then, in other parts of the site you'll be temporarily unbinding them before your .json calls:

$(document).unbind(".mine");

Got the idea from here while searching for an answer.

EDIT: I haven't had time to test it, alas.
