Jquery: Validate the mobile number field.
Hi, Below is the very simple code which is capable to validate the mobile number field on any .net form. jQuery(document).ready(function () { jQuery("#btnChangeNumber").click(function () { var mobileNo = jQuery("#txtNewMobileNumber").val(); if (mobileNo == "") { alert('Please enter mobile number.'); return false; } else { var rege = /^[0-9\+\-\(\)\s]*$/; if (!rege.test(mobileNo)) { alert('Please enter valid mobile number.'); return false; } } }); }); Enjoy :) !!!!
