不是本科可以吗？？

又不要PHP

已投

可惜我在广州

@Jackyang 不是出错，是正常的

@DavidNineRoc 不是AJAX

@23tl 这样是回到B页面的。

有邮箱么 或者 先加个微信聊聊呢

@leo laravel有

User::when($role, function ($query) use ($role) {
                    return $query->where('role_id', $role);
})->get()

有更简单的。我不喜欢写if ,喜欢写when

钱少了

@Openset 不懂，你有没有详细的？

@Openset 比如A有5个，，，B有3个.....C有2个
正确来说，，，ABACABACBA
如果按权重 ABCABCABAA

@Openset 2121有32个，但是你查一下，有很多中间是一样的
