In my $.ajaxSucess() function I need to find out if the response is json. Currently I am doing this:

$('body').ajaxSuccess(function(evt, xhr, settings) {
    var contType = xhr.getAllResponseHeaders().match(/Content-Type: *([^)]+);/);
    if(contType && contType.length == 2 && contType[1].toLowerCase() == 'application/json'){    
...

Is there a better way?
