3. Replace all the options with new options

$("#drpCountry").html('');

4. Replace items at a certain index

$("#drpCountry option:eq(1)").replaceWith('');

$("#drpCountry option:eq(2)").replaceWith('');

5. Set the element at index 2 to be selected


$("#drpCountry option:eq(2)").attr("selected", "selected");

6. Set the selected element by text

$("#drpCountry").val("India").attr("selected", "selected");

$("#drpCountry option:first").remove();

10. Remove last item

$("#drpCountry option:last").remove();

11. Get the text of the selected item

var selectedtext=$("#drpCountry option:selected").text();

12. Get the value of the selected item

var selectedvalue=$("#drpCountry option:selected").val();

13. Get the index of the selected item

var selectedIndex=$("#drpCountry option").index($("#drpCountry option:selected"));

14. Alternative way to get the selected item

var selectedItem=$("#drpCountry option:selected").prevAll().size();

15. Insert an item in after a particular position

$("#drpCountry option:eq(0)").after("");

16. Insert an item in before a particular position

$("#drpCountry option:eq(3)").before("");
