how can select 'select' tag value="az"

i've found way:

var val_ = "az";     var selects = $div.find("select").filter(function(index_){                 var val0 = $(this).val();                 return val0 == val_;             });

is there more elegant way it?

edit. question 'select' tag. of questions in stackoverflow child 'option' tag.

  1. you can use attribute equals selector [attribute='value'],for selecting using particular value
  2. use :has() selector checking selected option value
  3. :selected selector getting selected option

code:

$('select:has(:selected[value="az"])')

with variable can

var val_ = "az"; var selects = $('select:has(:selected[value="' + val_ + '"])');

for example :

var val_ = "az";  $('select').change(function() {    var selects = $('select:has(:selected[value="' + val_ + '"])');    console.log(selects.length);  });
