jsp页面:
时间戳的话需要引入： <%@ page import="java.util.Date"%>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/quickpay.js?time=<%= new Date().getTime() %>"></script> //未测试
<script type="text/javascript" src="${pageContext.request.contextPath}/js/quickpay.js?time=<%= Math.random()%>"></script> //已测试
html页面：已测试
<script src="/js/common/jquery-3.3.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
document.write("<script type=‘text/javascript‘ src=‘js/common/jquery-3.3.1.min.js?v=" + Date.now() + "‘><\/script>");
</script>
js添加后缀防止缓存
