I use Bootstrap switch plugin to make my checkboxes looks like switch buttons. I need to check if the checkbox is checked in jQuery. I Googled a lot and I tried some advice and code snippets but without success.

I think the cleanest code I found is

$('#checkbox').attr('checked');

but it still wont work on my website. I have declared jQuery in head. I try to use this snippets on non-bootstrap-switch-checkboxes but still no success.

JS:

 <script>

    $(function(){

      $(.odeslat).click(function(){

           $('#pozadavky').slideUp(100);

           $('#datumpick').slideDown(300);



       var typpaliva = 'nic';

       var malpg = 'nic';¨



       /***Important condition***/



       if ($('#uho').attr('checked')) {

            $.cookie(typpaliva, Diesel);

       }

       else {

            $.cookie(typpaliva, Benzin);

       }





 /**********************************************/





    $.ajax({

   url: 'http://podivej.se/script_cas.php',

   data: {druh: '30'},

   type: POST,

   success: function(data){

            alert($.cookie('typpaliva')); 

            alert($.cookie('malpg'));   

   }

   });



  });

});

</script> 

HTML

<input type=checkbox name=testcheckbox id=uho/>
