How to prevent script execution after BootstrapDialog opens?

I am using BootstrapDialog for showing some alerts.

    BootstrapDialog.alert({
          type:  BootstrapDialog.TYPE_DANGER,
          title: 'Oops! ',
          message: 'Error, occured',
          buttons: [{
              label: 'Ok'

          }]
      });
    window.location.replace("http://example.com");

I want that if dialog opens it doesn't redirect to another page. It should only redirect if a user clicks "OK" button, as if I were using alert in javascript.

You should attach the window.location code inside the buttons attribute. Try doing this:

BootstrapDialog.show({
    type:  BootstrapDialog.TYPE_DANGER,
    title: 'Oops! ',
    message: 'Error, occured',
    buttons: [{
        label: 'Ok',
        action: function(dialog) {
            window.location.replace("http://example.com");
        }
    }]
});
