            type: 'GET',
            url: url,
            dataType: 'json',
            success: function(result) {
                if(result.success) { 
                    console.log("We finally met our response!");
                    //Do something other here, for example:
                    //$('.result-message').html('RESPONSE MET!');
                    console.log("Response not yet met.");
            error: function() {
                console.log("There was an error.");
                //Want to repeat AJAX call also in case of error? 
                //Then just uncomment the following two lines:

We use the following wait() function to wait 1 second between each AJAX call:

function wait(ms) { const start =; while( - start < ms); }
