$(document).ready(function() {
$("#btnSubmit").click(function() {
Login();
});
});
function Login() {
if (Check()) {
LoginSuccess();
}
}
function Check() {
if ($("#ksbh").val() == "") {
alert("准考证号不能为空！");
$("#ksbh").focus();
return false;
}
if ($("#Yzm").val() != $.cookie('ValidateCode')) {

$("#Yzm").focus();
return false;
}

}
function LoginSuccess() {
$.ajax({

data: { ksbh: $("#ksbh").val()},
beforeSend: function() { $("#msg").html("loading......正在提交请稍候。"); },
