javascript - Jquery Chosen get the Id of un-selected value in dropdown -

i have manage id of selected option chosen plugin. here jsfiddle demo.

now not sure how id of unselected option. using code id of selected option.

 var selectedids = $(this).find('option:selected').map(function() {       if ($(this).attr('value') == params.selected)         return $(this).prop('id')      }).get();     alert(selectedids); 

when option deselected, change event, params object has deselected property can use you're using selected.

i made jsfiddle demonstrate: http://jsfiddle.net/1eut1c3d/

$("#chosen").chosen().on('change', function(evt, params) {    if (params.selected !== undefined) {      var selectedid = $(this).find('option:selected').map(function() {         if ($(this).attr('value') == params.selected)         return $(this).prop('id')    }).get();    alert("selected: " + selectedid); } if (params.deselected !== undefined) {     var deselectedid =   $(this).find('option').not(':selected').map(function() {       if ($(this).attr('value') == params.deselected)         return $(this).prop('id')          }).get();        alert("deselected: " + deselectedid);     } });
