How can reuse after .off?

https://jsfiddle.net/bpevmhxa/1/

How to reuse the .off after like on second input? Re enable or something? Any idea?

Thanks!

You need to explain what you are trying to achieve here using .off.

I want to display

new another text.

on second input without still do nothing on first.

I don’t get it? Do you want to remove the event handler from #test1 but keep it on #test2

$('#test1').on('focus', function() {
  $('p').html('another text.');
  $('#test1').off('focus');
});

$('#test2').on('focus', function() {
  $('p').html('new another text.');
});
