WordPress 使用今日诗词 API

看到龙笑天下和扶苏的网站评论框里会随机出现一个跟浏览者当前环境相关性很不错的古诗词名句，感觉很有趣，找到了相关的文章及代码自己也添加了一下。

function dr_show_jinrishici(){
    echo '<script src="https://sdk.jinrishici.com/v2/browser/jinrishici.js" charset="utf-8"></script> <script type="text/javascript"> jinrishici.load(function(result) { var c = result.data.content+" ---- "+result.data.origin.dynasty+"·"+result.data.origin.author+"《"+result.data.origin.title+"》"; document.getElementById("comment").placeholder=c;; }); </script>';
}
add_action( 'wp_footer', 'dr_show_jinrishici' );

以上是第一版代码，一般来说 Wordpress 直接使用即可什么都不需要修改，我用了子比主题害怕作者把评论框的 ID 魔改掉就 F12 检查了一波，试错了几次之后发现还好，并没有，评论框的 ID 还是 comment，什么都不用修改。

PS：在使用过程中发现当你处在主页或者没有评论框的位置代码也会执行，控制台会有一个报错。

• jquery.min.js?ver=3.6.0:2
• Uncaught TypeError: Cannot set properties of null (setting ‘innerHTML’)

向大佬龙反馈之后没一会儿新的方案就出来了，神速
