I wrote a line where if an input is clicked it hides a div. The div is a static utility nav bar that caused an issue with Android's native keyboard. here is the code but the issue is it runs 9 sometimes 10 times and my back end developer says it will be a performance issue. What can i do to prevent this from happening? I am new to javaScript and jQuery so getting this far is good for me.

```
    function utilityNav() {
  if($(window).width() < 891) {
  //Utility Mobile Nav background-color
  var div = $('.navbar-static-bottom').show();
  $('input').focus(function() {
     $('.navbar-static-bottom').fadeOut();
     $("."+$(this).attr('input')).fadeIn();
  });

  $('input').blur(function() {
     $('.navbar-static-bottom').fadeIn();
  });
  }
}
utilityNav();
$(window).on('resize', utilityNav);
$('input').blur(utilityNav);

```
