我这里有一个jsbin https://jsbin.com/wanegavisa/edit?html,js,console我正在尝试使用nodejs下载输出html https://output.jsbin.com/wanegavisa并解析出 javascript 中的内容jsbin 编辑器中的选项卡。我打算使用像 Cheerio 这样的 dom 解析器并获得第一个 <script> body 内的标签。我刚刚看到可以将脚本标签直接添加到正文中。
如何解析这样的文档才能得到包含
的字符串console.log('hi')
我可以从 src 等于此 url https://static.jsbin.com/js/render/edit.js 的脚本中选择同级脚本。但如果该网址发生变化，那么我就不走运了。

最佳答案
jsbin 有一个 api! :)
