copied!<p>Without any more insight into your specific requirements, I would not recommend a pure Javascript/HTML solution. From a user perspective you would probably get the best results writing a native application. However if it will be faster to use Javascript/HTML, I recommend using a local application hosting a lightweight web server to serve up your content. That way you can cleanly handle the file saving server-side while focusing the bulk of your effort on the front-end application. </p> <p>You can code up a web server in - for example - Python or Ruby using very few lines of code and without 3rd party libraries. For example, see:</p> <ul> <li><a href="http://fragments.turtlemeat.com/pythonwebserver.php" rel="nofollow noreferrer">Making a simple web server in python</a></li> <li><a href="http://microjet.ath.cx/webrickguide/html/Writing_Custom_Servlet.html" rel="nofollow noreferrer">WEBrick - Writing a custom servlet</a></li> <li><a href="http://www.blendedtechnologies.com/python-trick-really-little-http-server/220" rel="nofollow noreferrer">python-trick-really-little-http-server</a> - This one is really simple, and will easily let you server up all of your HTML/CSS/JS files:</li> </ul> <pre> <code> """ Serves files out of its current directory. Doesn't handle POST requests. """ import SocketServer import SimpleHTTPServer PORT = 8080 def move(): """ sample function to be called via a URL""" return 'hi' class CustomHandler(SimpleHTTPServer.SimpleHTTPRequestHandler): def do_GET(self): #Sample values in self for URL: http://localhost:8080/jsxmlrpc-0.3/ #self.path '/jsxmlrpc-0.3/' #self.raw_requestline 'GET /jsxmlrpc-0.3/ HTTP/1.1rn' #self.client_address ('127.0.0.1', 3727) if self.path=='/move': #This URL will trigger our sample function and send what it returns back to the browser self.send_response(200) self.send_header('Content-type','text/html') self.end_headers() self.wfile.write(move()) #call sample function here return else: #serve files, and directory listings by following self.path from #current working directory SimpleHTTPServer.SimpleHTTPRequestHandler.do_GET(self) httpd = SocketServer.ThreadingTCPServer(('localhost', PORT),CustomHandler) print "serving at port", PORT httpd.serve_forever() </code> </pre> <p>Finally - Depending on who will be using your application, you also have the option of compiling a Python program into a <a href="http://www.devshed.com/c/a/Python/How-Python-Runs-Programs/4/" rel="nofollow noreferrer">Frozen Binary</a> so the end user does not have to have Python installed on their machine.</p>
