如何将当前文档的innerHTML下载为文件？

Question

Is there a way I could download the current document's innerHTML as file programmatically ?

I've made the following attempt without success. It does download the current document's source, however that's not what I am looking for, since I want to preserve any post-load document modifications .

 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);

Perhaps something like this? It's probably not very cross-browser however, but it works in 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();
