javascript - Get the value that was just selected from a jQuery Chosen multiple select element -

i using jquery chosen convert select multiple select. when choose second item, gives me both selected items when $(this).val().

i want value item select @ moment.

following code.

$("#languageid").chosen().on("change",function() {   alert($(this).val()); }); 

html:

<select id="languageid" multiple >   <option value="hindi">hindi</option>   <option value="english">english</option> </select> 

according the documentation:

chosen triggers standard dom event whenever selection made (it sends selected or deselected parameter tells option changed).

therefore can access selected/deselected property on params object passed in change event callback. in other words, params.selected/params.deselected value of option element selected/deselected.

example here

$("#languageid").chosen().on("change", function(event, params) {   var value = $(this).val();   var changedvalue = params.selected || params.deselected;    // ... }); 

addressing comment below, check property on params object in order determine whether option selected/deselected:

$("#languageid").chosen().on("change", function(event, params) {   if (params.selected) {     console.log('the option: ' + params.selected + ' selected.');   }   if (params.deselected) {     console.log('the option: ' + params.deselected + ' deselected.');   } });
