jQuery表单验证编码

Question

我的Jquery验证无法正常工作，下面是脚本编码。 我正在

Fatal error: Uncaught exception

错误，不确定原因。 我知道原因之一可能是验证码不正确。 编码正确还是有错误？

<script type="text/javascript">     
$('form#contact').submit(function(e) {

    var isValidZip = /(^\d{5}$)|(^\d{5}-\d{4}$)/.test(jQuery('#form_zip').val());

您的JavaScript代码中包含php：

else if(!isValidYear || (year_number > <?php echo date('Y')?>)){
