如果你更新到 WordPress 的 4.2 版本，查看網頁源代碼你會發現 WordPress 會自動在加載一段用于支持 emjo 表情的腳本（JS+CSS）。對于大部分人來說，這個是十分雞肋的功能，再加上 GFW 的強大力量，反而影響加載速度。
我們有兩種解決方法：啟用或禁用。
原因分析
腳本就是類似下面的代碼：
- <script?type=“text/javascript”>
- “baseUrl”:“http://s.w.org/images/core/emoji/72×72/”,“ext”:“.png”,“source”:{“concatemoji”:“http://devework.com/wp-includes/js/wp-emoji-release.min.js?ver=4.2”}};
- ?!function(a,b,c){function?d(a){var?c=b.createElement(“canvas”),d=c.getContext&&c.getContext(“2d”);return?d&&d.fillText?(d.textBaseline=“top”,d.font=“600?32px?Arial”,“flag”===a?(d.fillText(String.fromCharCode(55356,56812,55356,56807),0,0),c.toDataURL().length>3e3):(d.fillText(String.fromCharCode(55357,56835),0,0),0!==d.getImageData(16,16,1,1).data[0])):!1}function?e(a){var?c=b.createElement(“script”);c.src=a,c.type=“text/javascript”,b.getElementsByTagName(“head”)[0].appendChild(c)}var?f;c.supports={simple:d(“simple”),flag:d(“flag”)},c.supports.simple&&c.supports.flag||(f=c.source||{},f.concatemoji?e(f.concatemoji):f.wpemoji&&f.twemoji&&(e(f.twemoji),e(f.wpemoji)))}(window,document,window._wpemojiSettings);
- ?<style?type=“text/css”>
- ?img.emoji?{
- ?border:?none?!important;
- ?height:?1em?!important;
- ?margin:?0?.07em?!important;
- ?background:?none?!important;
- ?}
- functions.php 文件中：
- function?disable_emojis()?{
- ?remove_action(?‘wp_head’,?‘print_emoji_detection_script’,?7?);
- ?remove_action(?‘wp_print_styles’,?‘print_emoji_styles’?);
- ?remove_filter(?‘the_content_feed’,?‘wp_staticize_emoji’?);
- ?remove_filter(?‘wp_mail’,?‘wp_staticize_emoji_for_email’?);
- ?}
- function?disable_emojis_tinymce(?$plugins?)?{
- ?if?(?is_array(?$plugins?)?)?{
- return?array_diff(?$plugins,?array(?‘wpemoji’?)?);
- ?}?else?{
- return?array();
- ?}
- Twitter Emoji 表情包下載，下載后直接解壓至主題目錄，文件夾名不變。將以下代碼放在主題目錄下的 functions.php 文件中：
- function?smilies_reset()?{
- ?global?$wpsmiliestrans,?$wp_smiliessearch;
- ?if?(!get_option(‘use_smilies’))?{
- return;
- ?}
- $wpsmiliestrans_fixed?=?array(
- ?‘:mrgreen:’?=>?“xf0x9fx98xa2”,
