提高 WordPress 后台加载速度

屏蔽自动更新及不需要的查询,将下面的代码粘贴到当前主题目录下的函数文件 functions.php 中

//去除后台没必要的功能
function disable_dashboard_widgets() { 
	remove_meta_box('dashboard_recent_comments', 'dashboard', 'normal');//近期评论 
	remove_meta_box('dashboard_recent_drafts', 'dashboard', 'normal');//近期草稿
	remove_meta_box('dashboard_primary', 'dashboard', 'core');//wordpress博客 
	remove_meta_box('dashboard_secondary', 'dashboard', 'core');//wordpress其它新闻 
	remove_meta_box('dashboard_right_now', 'dashboard', 'core');//wordpress概况 
	remove_meta_box('dashboard_incoming_links', 'dashboard', 'core');//wordresss链入链接 
	remove_meta_box('dashboard_plugins', 'dashboard', 'core');//wordpress链入插件 
	remove_meta_box('dashboard_quick_press', 'dashboard', 'core');//wordpress快速发布 
} 
add_action('admin_menu', 'disable_dashboard_widgets');
//移除 WordPress 加载的JS和CSS链接中的版本号
function wpdaxue_remove_cssjs_ver( $src ) {
	if( strpos( $src, 'ver=' ) )
	$src = remove_query_arg( 'ver', $src );
	return $src;

add_filter( 'style_loader_src', 'wpdaxue_remove_cssjs_ver', 999 );
add_filter( 'script_loader_src', 'wpdaxue_remove_cssjs_ver', 999 );
//移除自动保存
wp_deregister_script('autosave');
//移除修订版本
remove_action('post_updated','wp_save_post_revision' );
//后台禁用Google Open Sans字体,加速网站
add_filter( 'gettext_with_context', 'wpdx_disable_open_sans', 888, 4 );

Chrome crx Could not establish connection

Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.

Chrome 扩展 sendResponse 返回 undefined (时而返回 undefined 时而返回 成功)

chrome.runtime.onMessage.addListener(function (res, sender, sendResponse) {
    sendResponse('done');
    return true
});

多次尝试发现仅 manifest.json 中 content_scripts 设定的域名可以接受通信,非设定的域名无法通信。

另网页加载过程中通信也会造成返回失败,可以判断 tab 的 status 是否等于 complete,再进行通信

SpiderKeeper 上传找不到 Spider 的问题

1、使用命令行上传,查看提示错误信息,可能服务端缺少某些库

scrapyd-deploy <target> -p <project>

2、setting 中注释掉 log

# LOG_FILE = LOG_DIR + time.strftime("%Y-%m-%d") + '.log'
# LOG_STDOUT = True

一道题

一个二维数组,如何循环遍历将第一个数组作为下一级数组的父级,然后生成一个树型结构

<?php
$a = [['a'],['b'],['c'],['d'],['e']];
function getTree($list) {
    static $tree = array();
    static $i=0;
    $i++;
    $len = count($list);
    foreach($list as $k => $row) {
        if($i+$k == $len) {
            $tmp[] = $row[0];
            $tmp['child'] = isset($tree[count($tree)-1])?$tree[count($tree)-1]:$tree;
            $tree[] = $tmp;
            getTree($list);
        }
    }
    return end($tree);
}
$c  = getTree($a);
var_export($c);

结果

array (
  0 => 'a',
  'child' => 
  array (
    0 => 'b',
    'child' => 
    array (
      0 => 'c',
      'child' => 
      array (
        0 => 'd',
        'child' => 
        array (
          0 => 'e',
          'child' => 
          array (
          ),
        ),
      ),
    ),
  ),
)

PHP 使用 BerryChat 倍洽

$postUrl = 'https://hook.bearychat.com/=bwGFg/incoming/70e24a628680e77277fa35be7a11017x';
$curlPost = array("text" => json_encode($branch_data, JSON_UNESCAPED_UNICODE));

$curlPost = json_encode($curlPost);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $postUrl);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
	'Content-Type: application/json; charset=utf-8',
	'Content-Length:' . strlen($curlPost),
	'Cache-Control: no-cache',
	'Pragma: no-cache'
));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_exec($curl);
curl_close($curl);

iOS 微信浏览器 input 输入框BUG

iOS 微信浏览器 调起收起键盘 input 输入框失去焦点后无法点击的BUG

解决如下

$("input").blur(function () {
	setTimeout(() => {
		const scrollHeight = document.documentElement.scrollTop || document.body.scrollTop || 0;
		window.scrollTo(0, Math.max(scrollHeight - 1, 0));
	}, 100);
})

还有可能是 有些 display none 里面的元素有占位,特别是使用了 全屏 fixed 元素后,全屏无法点击
