您可以简单地用作${alert1} ，但是您需要在脚本中全局声明它，并确保alert1作为服务器端运行，因此您只能获取alert1值，该值在页面加载期间初始化，然后您对该变量，您无法在jstl中获得它。

<c:url var="selectDeliveryman" value="/admin/order/selectDeliveryman?id=${orderAttribute.orderId}&deliveryname=" />

<script>
function submit() {
   var alert1 = document.querySelector('input[name = "deliverystatus"]:checked').value;
   document.location="${selectDeliveryman}"+alert1;
}
</script>
