I have a multi select Listbox

```
<div id="multiselectList">
  <select>
    <option value="option1">Val 1</option>
    <option value="option2">Val 2</option>
    <option value="option3">Val 3</option>
    <option value="option4">Val 2</option>
    <option value="option5">Val 3</option>
  </select>

```

Suppose all the options are selected initially. Now I unselect option2 from multi select list. How can I know which option is currently unselected by the user. I used below code but it was giving me all the unselected values.

```
var unselectedValue = $("#multiselectList").find('option:not(:selected)');

```

Can anyone help me in finding the solution?
Thanks in advance
