jsp新手写了书上的代码发现<script></script>间的js代码都不执行代码如下


<%@ page contentType= "text/html" %>
<%@ page pageEncoding = "utf-8" %>
<%@ page import="java.time.LocalTime" %>
<%!    public int continueSum(int start,int end){
        int sum=0;
        for(int i=start;i<=end;i++){
            sum+=i;
        }
            return sum;
    }
%>
<HTML><body bgcolor=cyan>
<script>
  var userTime= new Date();
  var hour = userTime.getHour();
  var minute = userTime.getMinute();
  var second = userTime.getMinute();
  var millisecond = userTime.getMillisecond();
  document.write("<h2>浏览器时间："+hour+":"+minute+":"+second+":"+millisecond+"<br></h2>);
</script>
<img src = "image/time.jpg" width=180 height=120/>
<p style ="font-family:黑体;font-size:36;color:red">
<%
    LocalTime timeServer = LocalTime.now();
    int hour = timeServer.getHour();
    int minute = timeServer.getMinute();
      int second = timeServer.getMinute();
    int nano = timeServer.getNano();
      int millisecond = nano/1000000;
    out.print("服务器时间：<br>"+hour+":"+minute+":"+second+":"+millisecond);
    int start=1;
    int end = 100;
    int sum = continueSum(start,end);
%>
</p>
<p style ="font-family:宋体;font-size:33;color:green">
  从
  <%= start %>

  的<br>连续和是：
