如何对a元素应用悬停效果,但不对a类的元素应用active？
a:hover(not: .active)
似乎缺少某些东西.
我在下面列出了以下内容/home/david/conf/supervisor.conf:
[unix_http_server]
file=/home/david/tmp/supervisor.sock
[supervisord]
logfile=/home/david/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10 ; (num of main logfile rotation backups;default 10)
loglevel=info ; (log level;default info; others: debug,warn,trace)
pidfile=/home/david/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=false ; (start in foreground if true;default false)
minfds=1024 ; (min. avail startup file descriptors;default 1024)
minprocs=200
childlogdir=/home/david/tmp
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///home/david/tmp/supervisor.sock
并开始监督:
$ supervisord -c /home/david/conf/supervisor.conf
但是为什么supervisorctl还会使用默认值http://localhost:9001作为serverurl？ …
我正在尝试将cat输出传递给curl:
$ cat file | curl --data '{"title":"mytitle","input":"-"}' http://api
但input实际上是一个-.
当我将鼠标悬停在我的按钮上时,它会在开始转换时首先发出白色闪光.当我将css3转换应用到我的按钮时,为什么会出现闪烁？我的浏览器是Google Chrome
<button>Log In</button>?
CSS:
button {

background: -moz-linear-gradient(top, #ff3019 0%, #cf0404 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ff3019), color-stop(100%,#cf0404));

$baseUrl = 'http://foo';
$config = array();
$client = new Guzzle\Http\Client($baseUrl, $config);
为Guzzle设置默认标头而不将其作为参数传递给每个人的新方法是什么$client->post($uri, $headers)？
有$client->setDefaultHeaders($headers),但它是不推荐使用.
setDefaultHeaders is deprecated. Use the request.options array to specify default request options
我们叫这个表terms_relation:
+---------+----------+-------------+------------+------------+--+
| term_id | taxonomy | description | created_at | updated_at | |

| 3 | tag | non | 3434343434 | 3434343434 | |
| 4 | tag | non | 3434343434 | 3434343434 | |
+---------+----------+-------------+------------+------------+--+
这是表terms:

看看我的配置:
$ echo $GOPATH && ls -r $GOPATH
/home/cyrus/.go
src pkg bin
$ echo $GOROOT && ls $GOROOT
/usr/local/go
api AUTHORS bin CONTRIBUTORS doc favicon.ico include lib LICENSE misc PATENTS pkg README robots.txt src test VERSION
你可以看到我为它设置了路径$GOPATH.另外,我创建了我可能不需要的子目录.
题:
为什么以下命令会生成此错误消息？
$ go get code.google.com/p/go-tour/gotour
package code.google.com/p/go-tour/gotour: cannot download, $GOPATH not set. For more details see: go help gopath
你推荐的应该是我应该用于响应式布局的宽度？
/* Default Width: */
.container { width: 940px; margin: 0 auto; }
/* Smaller than standard 960 (devices and browsers) */
@media only screen and (max-width: 959px) {}
/* Tablet Portrait size to standard 960 (devices and browsers) */
@media only screen and (min-width: 768px) and (max-width: 959px) {}
/* All Mobile Sizes (devices and browser) */
@media only screen and (max-width: 767px) {}
/* Mobile Landscape Size to Tablet Portrait (devices and browsers) */
@media only screen and …我试图比较这三个,但它似乎只有array_map作用.
$input = array( ' hello ','whsdf ',' lve you',' ');
$input2 = array( ' hello ','whsdf ',' lve you',' ');
$input3 = array( ' hello ','whsdf ',' lve you',' ');
$time_start = microtime(true);
$input = array_map('trim',$input);
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "Did array_map in $time seconds<br>";
foreach($input as $in){
echo "'$in': ".strlen($in)."<br>";
}
