Html/Jsp常用的页面跳转方法

第一种：
<script language="javascript" type="text/javascript">
    window.location.href="login.jsp?backurl="+window.location.href;
</script>
第二种：
<script language="javascript">
    alert("返回");
    window.history.back(-1);　
</script>
第三种：　
<script language="javascript">
    window.navigate("top.jsp");　
</script>
第四种：　
<script language="JavaScript">
    self.location="top.htm";　
</script>
第五种：　
<script language="javascript">
    alert("非法访问！");
    top.location="xx.jsp";
</script>
第六种：　
servlet实现跳转-->request.getRequestDispatcher("/WEB-INF/pages/error.jsp").forward(request,response);
第七种：　
由于以上的跳转都是webRoot下的,或者已知完整url地址的跳转.如果html或者jsp是存放在WEB-INF下的,在使用struts的情况下,可以通过配置struts的路径获得完整的url地址,不使用struts实现WEB-INF下的页面跳转...

public class NavigateTo extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,

String url = request.getParameter("url");
request.getRequestDispatcher(url).forward(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,

doGet(request, response);
}
}
web.xml配置:
  <servlet>
    <servlet-name>NavigateTo</servlet-name>
    <servlet-class>cn.vicky.servlet.NavigateTo</servlet-class>
  </servlet>
使用的页面:
