submitFormOkay = false;
$(document.body).on("click", "a", function() {
    submitFormOkay = true;
});
window.onbeforeunload = function(event) {
    event.preventDefault(); 
    if (!submitFormOkay) {
        window.setTimeout(function () { 
            window.location = "{!!LaravelLocalization::localizeURL('/dashboard')!!}";
        }, 0); 
        window.onbeforeunload = null; // necessary to prevent infinite loop, that kills your browser 
    }
