Is there a way to create a text file on the client side and prompt the user to download it without any interaction with the server?
I know I can't write directly to their computer (security, etc.), but can I create the file and prompt them to save?
Simple solution for HTML5 browsers...
function download(filename, text) { var element = document.createElement('a'); element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text)); element.setAttribute('download', filename); element.style.display = 'none'; document.body.appendChild(element); element.click(); document.body.removeChild(element); }
form * { display: block; margin: 10px; }
use
download('test.txt', 'Hello world!');
You can use data URI. Browser support varies; seeWikipedia. Example:
text file
Octet stream is used to force download prompts. Otherwise, it may open in the browser.
For CSV you can use:
