复制代码代码如下:

 
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%> 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<base href="<%=basePath%>"> 

<title>My JSP 'checkbox.jsp' starting page</title>

<script type="text/javascript"> 
$(function(){ 

//$("#box").click(function(){ 
// if ($("#box").attr("checked")=="checked") { 
// alert("ss"); 
// }

alert("df"); 
} 

}) 
</script>
