jQuery选择：选择1个选项，然后在另一个选择菜单中取消选择相同的选项

Question

I have two same selects which use last version of jQuery Chosen plugin . What i want to achieve is if you select option in first select, disable this option in second select and vice versa. I tried to solve it with jQuery prop method, but it doesn't work.

Here is code:

<select data-placeholder= "Keyword" multiple style="width:300px;" name="keywordContainSelect" multiple class="selectKeyword">
                      <option value=""> </option>
                      <option value="1">apartments</option>
                      <option value="2">edward</option>
                      <option value="3">shutters</option>

                  </script>

The same question and solution is here , but the solution doesn't work with new version of jQuery Chosen plugin.

Answer 1

Here you are http://jsfiddle.net/aksvuy9q/2/

$(".selectKeyword").chosen().change( function() {
  var selectedValue = $(this).find('option:selected').val();        
  $(".selectKeyword").find('option[value="'+ selectedValue +'"]:not(:selected)').attr('disabled','disabled');
  $(".selectKeyword").trigger("chosen:updated");
});
