Eureka!
The solution is it:
var fun = function()
{
alert("hello");
}
MensajeConfirm(fun);
Then:
function MensajeConfirm(func)
{
swal({
title: "title",
text: "message",
type: "warning",
showCancelButton: true,
confirmButtonText: "Confirm",
cancelButtonText: "Cancel",
showLoaderOnConfirm: true,
allowOutsideClick: false,
focusCancel: true
}).then(function (eval) {
if (eval.value) {
//case press confirm
func();
//
}
if (eval.dismiss) {
///eval case esc|cancel
}
});
}

Answer 1

Create a callback function and pass it in your function.
function handleOkClick(){
// do your stuff
}
function ConfirmModalDelete(mensaje, handleOkClick) {
swal({
title: 'Are you sure?',
text: mensaje,
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then(function (result) {
if (result.value) {
handleOkClick();
}
});

Answer 2

Please use '.done' function:-
$("button").click(function() {
swal({
title: 'Are you sure?',
text: 'mensaje',
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
} ).then(function (hello) {
alert('dfasdfsd');
});
});

<script src="https://unpkg.com/sweetalert2#7.12.10/dist/sweetalert2.all.js"></script>
<button type="button">Click Me!</button>

Make sure you're using the latest version of SweetAlert2. Your code example works fine:
console.log(swal.version)
swal({
title: 'Are you sure?',
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then(function (result) {
console.log(result)
});

PS. notice that SweetAlert2 is a little bit different from SweetAlert, check the simple migration guide: https://github.com/sweetalert2/sweetalert2/wiki/Migration-from-SweetAlert-to-SweetAlert2
