问题:

By default, there are two buttons:"ok" and "cancel" in confirm().
Is there a way to rename them?

According to the standard that defines confirm(), there is no way to specify custom button labels.

The browser must display an OK/Cancel prompt to comply with HTML5.

回答2:

No, there isn't. Confirm only takes one argument and that is the message itself.

Keep in mind these dialogs are modal and blocking, which means once they are executed you lose control over the program flow. You'd be on a safer route if you implemented your dialogs using a javascript library of your choice or building yours.

There is a way IF you use a custom modal to confirm. Something like that:

$(document).ready(function() {
  $('#btn').on('click', function () {
    myApp.confirm('Are you sure?', 'Title', function () {
      $('.btn-no').text("No");
      $('.btn-yes').text("Yes");
  });
});

You can't change the buttons of the default confirm popup. A workaround is to recreate the whole popup in JavaScript. One such workaround is http://jqueryui.com/dialog/#modal-confirmation
