        e.preventDefault();

        if (window.confirm('¿Estas seguro?')) {
            var segundos = 15; //aki pones los segundos que quieres que se demore.
            $.ajax({
                type: 'GET',
                url: '/test/release.php',
                success: function (data) {
                    console.log('ok');
                    $("#container-msg-success").html(html_msg);
                    setTimeout(function () {
                        $(".content").fadeOut(1500);
