Jquery: $("input:checkbox:not(:checked)").each(function() { var columnName = $(this).attr('name'); $('td:nth-child(' + columnName + '),th:nth-child(' + columnName + ')').hide(); }); $("input:checkbox").click(function() { var columnName = $(this).attr('name'); $('td:nth-child(' + columnName + '),th:nth-child(' + columnName + ')').toggle(); }); HTML: <input type="checkbox" name="1" checked="checked"/> It works when I put values in the :nth-child(1) but not when I include the variable. Am I doing it

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: In SCSS , you can use @mixin and @extend to reuse code. For example: %even-row { background: pink; } @mixin even-rows-mixin($columns) { @for $i from 1 through $columns { &:nth-child(#{2 * $columns}n + #{$i + $columns}) { @extend %even-row; } } } li { @include even-rows-mixin(8); width: 12%; } Will generate: li:nth-child(16n + 9), li:nth-child(16n + 10), li:nth-child(16n + 11), li:nth-child(16n + 12), li:nth-child(16n + 13), li:nth-child(16n + 14), li:nth-child(16n + 15), li:nth-child(16n + 16) { background: pink; } li { width: 12%; } However

# [Python3爬虫] 爬取用户信息和全部微博（pyquery+selenium+mongodb ）

微博爬虫爬取手机版微博会比较简单，而手机版里面 微博彩板标准版 比较适合爬取。 需要代理IP和代理账号，IP代理最好不要使用免费的，例如西刺，免费代理多数挂的快，不稳定而且速度慢，速度慢就无法再超时设置的规定时间内加载出网页，导致出现异常，程序终止 微博账号购买： IP代理商： http://h.zhimaruanjian.com/getapi/#obtain_ip 数据存入MongoDB中，确保MongoDB已安装并且可以连接成功 主要步骤： 测试代理ip 模拟登陆 获取用户基本信息 获取用户所有微博 proxy = "http://58.218.200.248:3178"#设置代理IP # 测试代理IP def check_ip(): print(r'正在检查代理IP是否可用...') # 测试ip是否可用 proxies = { 'http': proxy, 'https': proxy, } print('当前测试的代理IP为：' + proxy) print('...') print('测试结果：') try: r = requests.get('http://ip111.cn/', proxies=proxies,timeout=3)#超时设置,避免使用不稳定的IP r.encoding = 'utf-8' doc = pq(r.text) # print(doc)
