如何将当前文档的innerHTML下载为文件？

Question

有没有办法innerHTML以编程方式将当前文档作为文件下载？

我做了以下尝试但没有成功.它确实下载了当前文档的源代码,但这不是我想要的,因为我想保留任何后载文档修改.

 var save = document.createElement('a');
 save.href = "my location href.attr";
 save.target = '_blank';
 save.download = fileName || 'unknown';

 var event = document.createEvent('Event');
 event.initEvent('click', true, true);
 save.dispatchEvent(event);

也许是这样的？但它可能不是非常跨浏览器,但它适用于Chrome.

function downloadCurrentDocument() {
  var base64doc = btoa(unescape(encodeURIComponent(document.documentElement.innerHTML))),
      a = document.createElement('a'),
      e = new MouseEvent('click');

  a.download = 'doc.html';
  a.href = 'data:text/html;base64,' + base64doc;
  a.dispatchEvent(e);
}
    
downloadCurrentDocument();
