Question

Please see coments in js code.

I have two checkboxes

<input type="checkbox" name="first" id="first" />
<input type="checkbox" name="second" id="second" />

Here is my javascript

$(function() {
  $('input[type=checkbox]').click(function() {
      /* 
       HERE i want to manipulate the checkbox which is not clicked
       NOTICE: they are only two checkboxes in page

       I know that I can do something like this
       if($(this).attr('id') == "first) {
           do something
       } else {
          etc...
       }
       But I think that way is against DNRY
       Can you recommend me some more elegenat solution ?

       /*
    }
    });
});

You just want to use .not to filter out the currently clicked item (this)

$(function() {
    var checkboxes = $('input[type=checkbox]');
    checkboxes.click(function() {
        var notclicked = checkboxes.not(this);
    }
});
