I don't think any browsers actually display the message you want any more, they all display a "default" message — Jaromanda X, Jul 03 '17 at 04:51

used below technique may be it is useful

      var is_template_save;
if (is_need_save == '0') {
    is_template_save = false;
} else {
    is_template_save = true;
}

window.onbeforeunload = function () {
    if (is_template_save) {
        return "Did you save your template?"
    }
}
function template_save() {
    is_template_save = false;
}
function template_unsave() {
    is_template_save = true;
}

Hope it make sense
