jsp设置

1.jsp设置全局路径变量

<%    String getContextPath = request.getContextPath();      String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+getContextPath+"/";    out.println("路径:"+basePath);%>

2.页面引用

<script>        var basePath = "<%=basePath%>";                console.log(basePath);        console.log("<%=basePath%>");</script>

3.jsp页面传递参数

url传参：

<a href="b.jsp?name="测试"">点击测试</a>

jsp：

<%    String name=(String)request.getParameter("name");       out.println("路径:"+basePath);%>
