Why JavaScript email obfuscation does not work
#!/usr/bin/env python
from requests_html import HTMLSession
import re
session = HTMLSession()
resp = session.get(put_your_url_here)
resp.html.render()
email = re.findall(r'[\w\.-]+@[\w\.-]+', resp.html.html)
print(email)
Here’s a page with different obfuscation techniques. Feel free to use it for scrapping.

That depends on how you implement it. I pondered on this for a while and in the end decided to use a fake link that triggers a piece of JS that injects the proper e-mail mailto: link into the DOM tree. That works. I tried the above script and it fails for brainbaking.com ;-) Cheers!

Well, you do not publish your email on the page, you dynamically create it upon interaction with the content. That falls out of the test cases. Although, as a visitor, I appreciate the elegance of the approach. This exact form acts somewhat similar and successfully prevents spam comments from bots. But again, it's a dynamic content creation _upon interaction_.

Should state the version of python and libraries needed to run your code. It's far from trivial to install requests_html and invoke without error.

Jim, Python 2 is deprecated, so it is Python 3. Installation is quite simple: $pip install requests-html
