Jquery Checkbox

I have four check boxes and when I click more than two of them then under the last clicked checkbox one I should get a <div><a href="#">Compare</a> </div> contains a compare link. It may be randomly. I tried to do this using JQuery and below is my code.I need improve one. The issue is I need when two of check box will check under the last one I should get visible the hidden div.

$(document).ready(function() {
  $('input[type=checkbox]').change(function(){ 
    if($('input[name=checkbox1]').size() == 1){    
      $('#checkbox1_compare').show();
    } 
    else { 
      $('#checkbox1_compare').hide();    
    }
  }) 
});

try this: (taken based on the source of @Nick Craver)

html:

<div id="link-compare"><a href="#">Compare</a></div>

js:

$(document).ready(function() {

  var refInputCheckbox = $('input[type="checkbox"]');

  $(refInputCheckbox).change(function(){ 

    $('#link-compare')
       .toggle(
          $(refInputCheckbox).filter(':checked').length > 1
       );

  });


});

You can check the .length and use .toggle() to show/hide based on how many are checked, like this should work:

$(function() {
  $('input[type=checkbox]').change(function(){
    $('#checkbox1_compare').toggle($('input[name=checkbox1]').length > 1);
  });
})

If you need to move the div/link elements to be after the last checked one, something like this would work:

$(function() {
  $('input[type=checkbox]').change(function(){
    var checked = $('input[name=checkbox1]:checked');
    $('#checkbox1_compare').toggle(checked.length > 1)
                           .insertAfter(checked.last());
  });
})
