Prevent closing modal window

I wonder if it is possible to prevent closing the modal window of Bootstrap when refreshing the page. Because we deal with different types of users, I need this to happen so I can change the status of banco de dados . With the code below, I was able to prevent users from closing the window by clicking outside it:

data-backdrop="static"

However, I also need to prevent the window from closing when I press the F5 key.

Thank you all!

There is no way to close the browser or refresh the page, but you can send the user a confirmation window, for example:

window.onbeforeunload = function() {
    return "Você não salvou a sua tarefa, gostaria mesmo de sair?";
};

The problem is that so the question will run in any situation, so you can check if the bootstrap window is visible before launching the confirmation:

In this way the confirmation only appears if the modal window is open:

$(window).bind("beforeunload", function() {
   if ($("#myModal").is(":visible")) {
       return "Você não salvou a sua tarefa, gostaria mesmo de sair?";
   }
});

Example usage:

<!DOCTYPE html>
<html>
<head>
    <title>Exemplo simples</title>
    <meta charset="utf-8">
    <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.4/css/bootstrap.min.css">
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script><scripttype="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.4/js/bootstrap.min.js"></script><scripttype="text/javascript">
    $(window).bind("beforeunload", function() {
       if ($("#myModal").is(":visible")) {
           return "Você não salvou a sua tarefa, gostaria mesmo de sair?";
       }
    });
    </script>
</head>
