就业前台servlet的路径${pageContext.request.contextPath}

servelet中:
    @Override
    protected void doPost(HttpServletRequest httpServletRequest,
                          HttpServletResponse httpServletResponse) throws ServletException, IOException {
        httpServletResponse.setContentType(CONTENT_TYPE);
 PrintWriter out = httpServletResponse.getWriter();
                out.write("<script language='javascript'>alert('提交成功，你的信息已经进入审核状态...');" +
                "location.href='"+httpServletRequest.getContextPath()+"/index.jsp';</script>");
}

jsp中:
 $("#grfw").click(function(){
                var lx = '<%=lx%>'; //类型
                if(lx != null && lx=='QY'){
                    location.href="${pageContext.request.contextPath}/pages/xgfw/dwfw/dwfwIndex.jsp"; //单位服务
                }else if(lx != null && lx=='XS'){
                    location.href="${pageContext.request.contextPath}/pages/xgfw/xsfw/xsfwIndex.jsp";  //学生服务
                }
                
            });
