copied!<p>ok, for web applications, support for python is going to be based on whether or not the browser has python support either provided as a plugin or built in to the browser. it probably isn't a good idea to rely on this being the case for most people who view the application. If you do, its just a matter of including the script in a <code><SCRIPT type="text/x-python" src="path-to-your-pyfile.py"></code> tag in the html. As an alternative, javascript, thanks to html5 now has support to write to files with both text and binary data. See the file api <a href="http://www.w3.org/TR/file-writer-api/" rel="nofollow">here</a>.</p> <p>if there there is a problem with using the file api, you can always create a link to a file for the user to save from javascript using data URIs like so:</p> <p>data:text/plain;base64,aGVsbG8gZnJvbSBhIGRhdGEgdXJpISEh</p> <p>here is an example of an html file that generates files on the fly from javascript note i rolled my own base64 encoder but there are many js libraries available for this.</p> <pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> <SCRIPT type="text/javascript" > var BASE_64_ALPHABET =//for encoding base64 [ 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z', 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z', '0','1','2','3','4','5','6','7','8','9','+','/' ]; var BASE_64_PAD = '='; function valueAt(source,index) { var result = null; if(source.charAt) result = source.charAt(index); else result = source[index]; if(result.charCodeAt) result = result.charCodeAt(0); if(result === null | result === undefined) return 0; return result; } function toBase64(data, offset, length) { var padSize = (3-(length % 3)); if(padSize == 3 && length != 0) padSize = 0; var bufferSize = ((4*(length-(length%3)))/3); + padSize; var buffer = new Array(bufferSize); var iterationLimit = length + (length % 3) - 1; var octetMask = 0xFF; var sextetMask = 0x3F; for(var sourceIndex=0,destinationIndex=0;sourceIndex<iterationLimit;sourceIndex+=3,destinationIndex+=4) { var readBlock = ( ((valueAt(data, offset+sourceIndex) & octetMask) << 16) | ((valueAt(data, offset+sourceIndex+1) & octetMask) << 8) | (valueAt(data, offset+sourceIndex+2) & octetMask) ); buffer[destinationIndex] = BASE_64_ALPHABET[(readBlock >>> 18) & sextetMask]; buffer[destinationIndex+1] = BASE_64_ALPHABET[(readBlock >>> 12) & sextetMask]; buffer[destinationIndex+2] = BASE_64_ALPHABET[(readBlock >>> 6) & sextetMask]; buffer[destinationIndex+3] = BASE_64_ALPHABET[readBlock & sextetMask]; } for(var i = 0; i < padSize; i++) buffer[buffer.length - 1 - i] = BASE_64_PAD; return buffer.join(""); } function makeDataURI() { var data = document.getElementById("datasource").value; var mime = document.getElementById("mimesource").value; alert("data:"+mime+";base64,"+toBase64(data,0,data.length)); } </SCRIPT> </head> <body> <INPUT id="datasource" type="text" value="enter your file data here"></INPUT> <INPUT id="mimesource" type="text" value="enter your mime type here"></INPUT> <INPUT type="button" onclick="makeDataURI();" value="Generate URI"></INPUT> </body> </html> </code></pre>
