Get the current value in bootstrap-select

instead of e.target.value, you can use $(this).find("option:selected").text();

 $('.selectpicker').change(function () {
        var selectedItem = $('.selectpicker').val();
        alert(selectedItem);
    });

<select class="selectpicker" multiple data-selected-text-format="count > 1">
	<option value="1">Item 1</option>
	<option value="2">Item 2</option>
	<option value="3">Item 3</option>
	<option value="4">Item 4</option>
	<option value="5">Item 5</option>
</select>

I think the answer may be easier to understand like this:

$('#empid').on('click',function() {
  alert($(this).val());
  console.log($(this).val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<select id="empid" name="empname" multiple="multiple">
  <option value="0">item0</option>
  <option value="1">item1</option>
  <option value="2">item2</option>
  <option value="3">item3</option>
  <option value="4">item4</option>
</select>
<br />
Hold CTRL / CMD for selecting multiple fields

If you select "item1" and "item2" in the list, the output will be "1,2".
