Question

$(document).ajaxComplete(function(event, request, settings) {
        alert(request.responseText);
});

Here in this code, it is alerting both js,css file and the plain response. Is there anyway to get only the plain responses.

Answer 1

From your question it seems you are loading via ajax several resources, so you could get the content-type response header inside the callback and, if it’s text/html, you alert the responseText

$(document).ajaxComplete(function(event, request, settings) {
     var ct = request.getResponseHeader('content-type');
     if (ct === "text/html") {
         alert(request.responseText);
     }
});
