Genius在其embed.js中使用document.write，因此我们需要做相同的操作或替换write函数
请注意，这些脚本将允许API中的任何代码在您的站点范围内运行。

iframe文档.write
**注意：**由于iframe限制，第一个示例在SO中不起作用，但它在jsfiddle和您的站点中起作用

const result = `<div id='rg_embed_link_437103' class='rg_embed_link' data-song-id='437103'>Read <a href='https://genius.com/Ed-sheeran-thinking-out-loud-lyrics'>“Thinking Out Loud” by Ed Sheeran</a> on Genius</div> <script crossorigin src='//genius.com/songs/437103/embed.js'><\/script>`

let ifrm = document.getElementById('song');
try {
  let ifrWin = ifrm.contentWindow || ifrm.contentDocument.defaultView
  ifrWin.document.write(result);
  ifrWin.document.close();

} catch (e) {
  console.log(e.message)
}

/* does not work
const [html,scriptStr] = result.split('<script');
console.log(html)
const div = document.getElementById('mySong')
div.innerHTML = html;
const scriptSrc = scriptStr.match(/src='(.*?)'/)[1]
console.log(scriptSrc);
const script = document.createElement('script');
script.setAttribute('crossorigin',true)
script.src=`https:${scriptSrc}`;
document.querySelector('head').appendChild(script);
// div.appendChild(script); // does also not work

<iframe id="song"></iframe>

替换文档.write

const result = `<div id='rg_embed_link_437103' class='rg_embed_link' data-song-id='437103'>Read <a href='https://genius.com/Ed-sheeran-thinking-out-loud-lyrics'>“Thinking Out Loud” by Ed Sheeran</a> on Genius</div> <script crossorigin src='//genius.com/songs/437103/embed.js'><\/script>`

   
const [html,scriptStr] = result.split('<script');
console.log(html)
const div = document.getElementById('song')
div.innerHTML = html;
const scriptSrc = scriptStr.match(/src='(.*?)'/)[1]
console.log(scriptSrc);
const script = document.createElement('script');
script.setAttribute('crossorigin',true)
script.src=`https:${scriptSrc}`;

const saveWrite = document.write;
document.write = str => div.innerHTML += str;

document.querySelector('head').appendChild(script);

<div id="song"></div>
