How to fix all requests and answers on the page and perform the actions necessary for each answer

- this is any way to track the entire request made on the page, called by a script, click or something else, it should not depend on any block or script code, just keep track of what the request did using jquery and Javascript

Example:

// keep track of all the request made on the page.

monitor{

    success:function(){

    }
    error:function(){

    }
}

You cannot track all requests made on a web page. However, you can keep track of queries that were made using jQuery by replacing $ .ajax bay the wrapper.

Example of replacing a plugin:

(function($, undefined) {
    // a private variable which will store the current active monitors
    var monitors = [];

    // a public API to add a monitor.
    $.monitorAjax = function(monitor) {
        monitors.push(monitor);
    };


    // here starts the implementation.

    // a function to wrap a callback (error or success) to make monitors functions called.
    var wrapCallback = function(name, settings) {
        return function() {
            for(var i = 0; i < monitors.length; i++) {
                var monitor = monitors[i];
                if(monitor[name] != null) monitor[name].apply(this, arguments);
            }
            if(settings[name] != null) settings[name].apply(this, arguments);
        };
    };


    // replace $.ajax by a wraped version which will replace success and error callbacks by wrappers.
    // note that you may also track calls and their settings if you want.
    var unwrappedAjax = $.ajax;
    $.ajax = function(url, settings) {
        if(settings == null) settings = {};

        var wrappedSuccess = wrapCallback("success", settings);
        var wrappedError = wrapCallback("error", settings);

        var wrappedSettings = $.extend({}, settings, {success: wrappedSuccess, error: wrappedError});

        return unwrappedAjax(url, wrappedSettings);
    };
})(jQuery);

jQuery :

var original_jquery_ajax=$.ajax;
$.ajax=function(){
    var a_fn, a_url;
    var cb=function(data, status, settings){
        a_fn(data, status, settings);
        console.log(a_url, data); // <-- here
    }
    for(var i=0; i<arguments.length; i++)
        if(arguments[i] instanceof Object){
            if(arguments[i].success){
                a_fn=arguments[i].success; arguments[i].success=cb;
            }
            if(arguments[i].url) a_url=arguments[i].url;
        }
    if(typeof(arguments[0])=="string") a_url=argements[0];
    var aj=original_jquery_ajax.apply(null,arguments);
    var done_original=aj.done;
    aj.done=function(cb_fn){
        a_fn=cb_fn;
        done_original(cb);
        return aj;
    };
    return aj;
};

, $.ajax(url), url
