The raw javacript code to intercept ajax calls:

(function(send) {
    XMLHttpRequest.prototype.send = function(body) {
        var info="send data\r\n"+body;
        alert(info);
        send.call(this, body);
    };
})(XMLHttpRequest.prototype.send);

The jQuery code to intercept ajax:

$.ajaxSetup({
    beforeSend: function (xhr,settings) {
        alert(settings.data);
        alert(settings.url);
    }
});
