Calling Python from JavaScript
I have a test.py and test.js.
I want to be able to run my test.py by opening test.js. I don't know how to create an api because it's not a web app, it's just 2 files sitting on my linux mint desktop.
I don't want to use npapi, because it's just a simple task, i don't want to use pyjamas because it's too hard to install the pyjamas desktop, so how to do it?
please note that i can use php, ajax, jquery instead of javascript, if it could be done with these languages. I am also able to use C++ or C instead of python. I just want to know a simple way to do it.
I know this can be done if i use java instead of python, but i want to know if i can do it with python, C or C++.
If you put your test.py file where ever you put your cgi files, (I think it's /usr/lib/cgi-bin by default for apache on ubuntu linux), you should be able to run the python file just by making a request to it's address.
If you just want to run the python file, and not use its output in the browser afterward,
you could probably get away with something like:
document.write('<img src="http://localhost/cgi-bin/test.py" />');
if you want to use the output in the browser, you will probably be best served by using jQuery or some other library to do an easy ajax call.
something like:
jQuery.get('/cgi-bin/test.py', function(data) {
//do stuff with the data
})
would probably do you just fine.
the second method would require that you also use apache, or equivalent, to serve the test.js file from localhost because jQuery ajax generally requires requests to go to the same domain that the script is running on.

I would like to basically call a python script from HTML, after the script is called and it finished running, I would like to execute a javascript file(wich I know how to do.) Now my question is: Can I do this with just pure HTML and javascript or do I need to get a library for python? If I dont need a library, how would I go about doing this?
You can use Two Python libraries.
Django
Flask
I recommend Django. Django is easy and fast to make.
the Flask is more complex but you can make more detail functions.
Can I do this with just pure HTML and javascript?
You might want to execute python on the browser, then look at something like this http://www.skulpt.org/, but the most common use case is that no, you need to execute javascript on the browser client-side and python on server-side
So no, you need something that executes python in a web server (apache/nginx) context, like
gunicorn (standalone/wsgi)
uwsgi (standalone/wsgi)
mod_python (apache module)
Then you would execute like this for example
browser ---http---> server(nginx) ---wsgi---> python_server(uwsgi)+library(Django)

I have a website written in html and I have a button that when clicked should run a python script. The button is programmed in javascript, and I have seen on this site how to connect javascript and python together, but the problem is that I'm running the website using xampp and localhost, so I don't know the configurations to run the python code. I have tried to use up mod_wsgi, but the instructions are very confusing and I really have no idea what I'm doing.
I don't want to use JQuery or Ajax, I'd rather use just regular javascript to run the python code. How would I accomplish this? Basically I just want the button to run a python script I have, which is in the same directory as the website is. I don't want to run the python code from localhost directly, rather I want to reference and run it from the javascript code for the button.
Edit: it has been pointed out to me that JavaScript and python are connected through a client server relationship. Therefore my question is how to run the python code through a webserver from xampp.
Thanks in advance

Convert a PHP script into a stand-alone windows executable
(7 answers)
Closed 9 years ago.
I want to make windows standalone app with php, even i want to use database, javascript in that application.
Note : i don't want to give source code to user.
I should be like exe file which user can run.
If going with Windows, try WinBinder. It allows you to develop native Windows applications using PHP.
It also supports SQLite, so you don't need a database server
Also this answer will help you
I use phc to create .exe files out of my PHP source code. It works quite well, but it's mostly good for console applications rather than full webpages.
However, you could have your PHP script include a basic "server" that allows the browser to communicate with it - I have done this in the past too, and while it might seem daunting the results were very rewarding.
I want to convert some web pages with javascript to plain html, and I found there several ways(pls tell me if I'm wrong):
Use Jython, an example: http://blog.databigbang.com/web-scraping-ajax-and-javascript-sites/
Use Java together with htmlunit
Use a proxy, an example: http://grep.codeconsult.ch/2007/02/24/crowbar-scrape-javascript-generated-pages-via-gecko-and-rest/
Use python together with qt or PyV8
Because I want to make a tiny tool to meet my request, and I thought it somewhat complicated to install V8 and qt, although python is my first choice.
So I tried to make a proxy with gecko, but it seems need a DISPLAY which I can not afford in a remote Linux server.
Now I am trying to use jython, but it seems there is no simple way to just convert a whole page to plain html.
Actually, I want to ask is there a way to convert a web page contains javascript to plain html, just like the brower does. Can node.js do this job?
I've recently built a server on top of PhantomJS that does this. I highly recommend this route.
http://phantomjs.org/
Basically, you write a quick script that has PhantomJS run the page, and configure a trigger method that lets you know the page is finished and sends the data off. My version used the built-in HTTP server, so PhantomJS easily served up the results on its own. This takes about 15 lines of code to do. (Sorry, can't paste it here... wrote it on work time. But, check out the example on their home page. It's almost complete!)
I'm working with an API with a feature that can only be accessed (easily) using Javascript, but I want to use the API to save a .txt file to my server. Is there any way to achieve this on a Mac OSX machine? I know that JS running in a browser is prohibited from doing this, so I guess this is really a two part question: (1) what's the simplest way to run a 10 line JS script on Mac OSX and (2) how would I write data to a txt file doing this?
You could go for a headless browser for example PhantomJS. I haven't used it, but it should run JS well.
The same restrictions apply though, no filesystem access from JS.
Unless you use something like the plugin framework in FF, in that case you have elevated rights for the scripts.
Besides that you could create a wrapper in php, perl or other language, and pass on the data from JS to them in an ajax call, and they write the txt for you.
