新老客户大回馈,云服务器低至5折

在自己做一个项目玩时,在做评论的时候。

选中了semantic.js原型,这个在国内用的不是很多,但是在github上star数量很高,想当初我想找一个js框架是就在上面找的。

semantic中文网:http://www.semantic-ui.cn/

用了他的评论UI组件:http://www.semantic-ui.cn/views/comment.html

如下图所示

但是它的评论框不能用表情,于是在网上找了一个emoji 选择器

github地址:https://github.com/OneSignal/emoji-picker

它的效果如下

然后和semantic集成效果如下:

接下来,如果你的数据库编码不对,会报错

要将你的数据库编码方式从utf-8变成utf8mb4

mysql版本要5.5+

1. 修改表字段字符集为utf8mb4

alter table 表名 modify column 字段名 varchar(500) character set utf8mb4;

2.修改表字符集utf8mb4

alter table 表名 charset=utf8mb4;

3.修改数据库的字符集utf8mb4

alter database 数据库名 character set utf8mb4;

修改完后记得重启一下mysql服务

windows下重启mysql服务的办法:

1.我的电脑——(右键)管理==>服务与应用程序==>服务==>MYSQL==>停止==>开启

2.Win+R==>net stop mysql==> net start mysql

如果上面不行的话,那就祭出大招:改mysql配置my.ini

[client]
default-character-set=utf8mb4
[mysqld]
character_set_server=utf8mb4

然后重启

查看mysql编码方式如下

然后就可以放心的存储表情

ok.

题外话:

可以用其他公司提供的评论框组件,功能会更加完善。
