(1)在Servlet中放回一个参数aa,在界面上显示出aa所对应的值,比如显示“取款100元整”
request.setAttribute("aa", "取款"+QuKuanJinE + "整!"); // ////////跳转界面 request.getRequestDispatcher("QuKuan.jsp").forward(request,response);
<tr> <td colspan="3" align="center"><font color="#FF0000">${aa}</font> <input type="button" value="返回" onclick="window.location='index.jsp'"></td> </tr>
