ball = 5
seeds = [].tap{|s| (0..19).to_a.each{|i| s << 10*i + ball}}

自定义的ruby struct怎么重载方法

set_1 = (01..11).to_a
set_2 = (12..22).to_a
set_3 = (23..33).to_a
# 23合并,随机取出3个
# 随机20次
# 20个结果做Comfirm
# 不能都属于set_2 也不能都属于set_3
set = set_2 + set_3
Comfirm = Struct.new("Comfirm", :is_legal, :data) do

在mysql中存在着各种utf8编码格式,如下表:
1)utf8_bin
utf8_bin将字符串中的每一个字符用二进制数据存储,区分大小写。

utf8_genera_ci不区分大小写,ci为case insensitive的缩写,即大小写不敏感。
3)utf8_general_cs
utf8_general_cs区分大小写,cs为case sensitive的缩写,即大小写敏感。
执行如下命令:
create table test_bin (
name varchar(32) not null prim ...
很明显,php不支持$_PUT
PUT方法提交的简单form可以
parse_str(file_get_contents('php://input'), $data);
Content-Type:multipart/form-data; 这样的form通过put方法提交就很尴尬了
解决这个问题得有思路
先去找找开源代码

很久以前,form的post需要刷新页面。后来有人发明了ajax,又有人开源了jquery,我们的form可以ajax post而无须刷新页面。 var url, method, data, element = $('form'); url = element.attr('action'); method = element.attr('method'); data = $(element[0].elements).serializeArray(); $.ajax({ url:url, type:method, data:data });但存在 ...
