javascript - is(':visible') not working -

-

hey guys new jquery , going throught modal.js code , found below code: 

$target.one('show.bs.modal', function (showevent) {   if (showevent.isdefaultprevented()) return // register focus restorer if modal shown   $target.one('hidden.bs.modal', function () {     $this.is(':visible') && $this.trigger('focus')   }) })

i tried understand above code , made fiddle.

now if see if conditional in code : 

 if ($this.is(':visible')) {         $('input').trigger('focus');         console.log($this + ' ' + 'is visible');      } else {         console.log($this + ' ' + 'invisible');     }

now if have following display rule i.e.

input {   display:none; }

the if condition still passes , thats 1st difficulty . why if condition pass ??

my secound difficulty line inside if condition i.e. 

$this.trigger('focus');

now though if condition passes input does't focus . why ??

thank .

i've made minor chances code, , seems work me:

$(document).ready(function () { $target = $('input'); $target.trigger('focus');  $target.one('show.bs.modal', function (showevent) {     $this = $(this);      console.log($this);      if ($this.is(':visible')) {         $this.focus();     } else {         console.log($this + ' ' + 'invisible');     }      $target.one('hidden.bs.modal', function () {         $this.is(':visible') && $this.trigger('focus')     }); });  $target.trigger('show.bs.modal'); });

to focus element, don't need fancy code. .focus() function job you! , actually, think that's it, can't remember else changed honest. :p
