我正在使用以下代码来初始化 jQuery DataTables：

var oTable = $('#qpidvulh_to-do_list').dataTable( {
    "columns": [
        {
            "data": "item",
            "className": "editable"
        }
    ]
} )

此代码的问题在于它将editable类添加到th每列的 ，即使我只想将它添加到td每列的 。

我怎样才能让代码只将editable类添加到每列的单元格而不是它们的标题？

我有一个包含电话号码的MySQL列,问题是它们的格式不同,例如:

• 2125551212
• 212-555-1212
• (212)5551212

我想知道是否可以采用现有的10位数字,删除格式,并将它们全部更改为以下格式:(212)555-1212

不重复,因为我希望更新几千个条目而不是屏蔽新条目.

我在WordPress中使用W3 Total Cache将我的所有静态文件传输到CloudFront.除.woff和.otf字体文件外,所有文件类型都能正常工作.以下是W3TC如何配置来处理CloudFront:

知道为什么我会失踪吗？

我只是在我的WordPress网站上手动安装了一个新的插件,在MySQL中为插件的条目创建了一个表,当我尝试打开使用该插件的页面时,我收到此错误:

DataTables warning (table id = 'to-do_list'): An error occurred while 
connecting to the database 'wordpress_clouse'. The error reported by the 
server was: SQLSTATE[HY000] [2002] Can't connect to local MySQL server 
through socket '/var/lib/mysql/mysql.sock' (2)

这是我的配置文件中列出的MySQL信息(我认为是正确的):

"type" => "Mysql",
"user" => "root",
"pass" => "******",
"host" => "localhost",
"port" => "",
"db"   => "******"

这是/etc/my.cnf文件的主要内容:

# The following options will be passed to all MySQL clients
[client]
#port       = 3306
socket      = /var/run/mysqld/mysqld.sock

# The MySQL server
[mysqld]
#port       = …

我有一个关于Chrome和Safari中不透明度转换的错误.当我将鼠标悬停在父div上,触发子div上从0到1的不透明度转换时,子div下面的内容会抖动一段时间.

我已经尝试使用-webkit-font-smoothing: antialiased;上body,但效果仍然存在.有什么想法吗？您可以在此处查看问题(使用Chrome或Safari,将鼠标悬停在顶部菜单中的"帐户"链接上,您会看到闪烁).

我有一个表格单元格,其中包含用<p>标签包装的内容:

<td class=" address"><p>
    Content goes here
</p></td>

我想<p>删除标签,所以它看起来像这样:

<td class=" address">
    Content goes here
</td>

我尝试了以下jQuery,但它没有用.有人能指出我正确的方向吗？

$('.address p').replaceWith('');

我最近将EC2实例中/ var目录的所有权从"root"更改为"ec2-user",一旦我这样做,我就无法SSH回到服务器中(即使端口22在安全性中打开)组).现在,当我尝试通过该实例或任何新实例进行连接时,我收到以下消息:

Error connecting to ________, reason:
-> Connection refused

当我检查系统日志时,我看到:

启动sshd:/ var/empty/sshd必须由root拥有,而不是group或world-writable.

[FAILED]

关于如何重新进入服务器的任何想法？我尝试创建一个新实例并在那里安装旧卷,但我甚至无法SSH到新实例,因为我得到相同的"连接被拒绝"消息.

根据Google PageSpeed的推荐,我将大部分CSS都内联了.以前,我通过W3 Total Cache缩小了我的所有CSS,但是现在我内省了很多CSS,加上控制Google字体的所有CSS.

现在谷歌字体没有出现在移动设备上,但它们确实出现在台式机上.有这种情况的原因是什么？此处的移动屏幕截图显示未加载的字体.
