JS中怎么调用<%%>的值

示例代码一：

<% 
String usercode = request.getParameter("usercode");//用request得到 
%>
<script  type="text/javascript">  
<span style="color: #0000ff">function</span><span style="color: #000000"> toGjzxt(){
    </span><span style="color: #0000ff">var</span> usercode = "&lt;%=usercode %&gt;";<span style="color: #008000">//</span><span style="color: #008000">获取usercode参数值</span>

 }
 </script>

示例代码二：

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
//注意在Script的标签里面拼接不加“+”号
<script type="text/javascript" src="<%= path %>/scripts/jquery-1.7.2.min.js"></script>
