Is it possible to retrieve a Javascript file from a server?

Question

In Python, I can retrieve Javascript from an HTML document using the following code.

import urllib2, jsbeautifier
from bs4 import BeautifulSoup

f = urllib2.urlopen("http://www.google.com.ph/")

soup = BeautifulSoup(f, "lxml")
script_raw = str(soup.script)

script_pretty = jsbeautifier.beautify(script_raw)
print(script_pretty)

But how about if the script comes from a Javascript file on the server, like:

<script src="some/directory/example.js" type="text/javascript">

Is it possible to retrieve "example.js"? If so, how?

Context: I'm examining the Javascript of phishing web pages.

In urllib use urlretrive here is an example http://stackoverflow.com/questions/257409/download-image-file-from-the-html-page-source-using-python — Hisham Karam, Oct 14 '16 at 05:25

The easiest way is to right click on that page in your browser, choose page script, click on that .js link, and it will be there.

If you want to load at run time, like some part of your javascript is dependent on other javascript, then for loading javascript at run time, you can use require.js .
