提示:本篇将完成菜品管理的前后端开发
信息获取:先查看新增菜品,再查看展示页面信息进行补充。
这里我们使用黑马提供的下载资料。下载后,向数据库导入菜品管理SQL;
之前已经讲了导入方法,这里就不赘述了。
详情请看:点我第三部分
图片远程调用服务器,可能是黑马已经删了,所以不显示。
理由:查看数据库tb_dish表的image字段
解决办法
IDEA
VsCode
修改id回显
在价格前加上¥
将时间修改为年月日时分秒格式
口味需要客户进行书写,不够友好,我们的目标如下,使得用户直接选择就可以。
下面就不一 一放图了,直接给源代码:
具体代码如下:

目标:
修改标题
修改背景图
添加背景图
修改背景图路径
效果
我们发现,登录界面挡住了小车,修改css样式:
.login {
display: flex;
justify-content: flex-end; /* 修改为居右对齐 */
align-items: center;
height: 100%;
padding-right: 20%; /* 添加右内边距以保持20%间距 */
background-image: url("../assets/images/login-background1.jpg");
background-size: cover;
}
结果如下图:
