jsp中的button onclick事件失效

-飞奔的小蜗牛- 2011-04-17 09:49:44

发布在tomcat下，一直运行没问题，今天去吃晚饭回来，继续做了几个页面，跑来看时突然发现以前有个页面的button按了什么反应没有。
查资料书，又baidu还是搞不清楚到底因为啥？

重新发布还是不行...

路过的大大们。。求拯救。。明天上午要交这个项目作业。欲哭啊...

button失效的jsp页面代码如下：

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<%

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 'vetSearch.jsp' starting page</title>

	<link href="layout.css" rel="stylesheet" type="text/css" />



  	<script type="text/javascript" language="javascript">

	<!--

		function check2(){

		       if(document.petS.pet_name.value==""&&document.petS.pet_owner.value==""){

		         alert("请输入一个查询项！");

		         document.petS.pet_name.focus();

		         document.petS.pet_owner.focus();

		         return false;

		       }else{

		         document.petS.action="petSearch";

		         return true;

	    }

	    function exit(){

	      window.location.href("employeeLogin.jsp");

	    }

	    function addPet(){

	      window.location.href("addPet.jsp");

	    }

	    function addOwner(){

	      window.location.href("addOwner.jsp");

	    }

    -->

	</script>
