How can i create a local file using javascript?

Question

The problem is, i want to save a text file (or anything) in the local system using javascript.

javascript does not have access to the file system. This is not possible. — Amir Raminfar, Aug 17 '11 at 20:21
Indeed, but you can store data through other means. Is it just arbitrary data you'd want to store, or do you actually need a file somewhere? — TJHeuvel, Aug 17 '11 at 20:21
like once the user have completed writing in an input box in the page, i want to give them the option to save as text file. — shahalpk, Aug 17 '11 at 20:23

@Amir Raminfar, you're incorrect actually. Some browsers have a filesystem API, however most require that the page be loaded from a `file://` path to use it. — zzzzBov, Aug 17 '11 at 20:35

There is no practical real world way to create a local file. However if you want to to just store data locally then try these two methods.

The old way:

The new way:

Alternatively, you could create a file with php and serve it out to the user.

You can't write to the user's file system. But you initiate a file download that the user can then save wherever they'd like.

In PHP, you can just use

header('Content-Disposition: attachment; filename=file.txt'); 
echo('File contents');
