Recently i have worked drop down list data validation using JQuery. Now i would like to explain how to validate the data of drop down list using JQuery .In previous articles i have given an example on Jquery drop down validation,JQuery allow only numbers.Here in this post i will given script for Validate DropdownList Using JQuery

Example:

   $(document).ready(function () {
    $('#btnsubmit').click(function(){
        cntydr = $('#ddlcountry');
        if (cntydr.length == 0 || $(cntydr).val() == "") {
            alert("Please Choose Country");
