Small question:
Is it possible to make new file using JavaScript? I'm looking for something like the PHP function fopen and fput. Is this totally impossible? And what about JavaScript function OpenTextFile()?

@IswantoSan That is not a dupe, both the Q and A imply IE and ActiveX.bfavaretto– bfavaretto2013-04-02 00:33:40 +00:00Commented Apr 2, 2013 at 0:33

That can't be one from the client side. Send the data to the server, then serve a new txt file for download.bfavaretto– bfavaretto2013-04-02 01:08:25 +00:00Commented Apr 2, 2013 at 1:08

Is the text file just for storing data you're going to use in the javascript application later, or do you need to use it otherwise like a text file, i.e., in other applications?jwrush– jwrush2013-04-02 01:11:42 +00:00Commented Apr 2, 2013 at 1:11

Only possible with HTML5 apparently.
And here's creating text files:

i have used the second link in IE . but no result. Is it need any special plug in ?
Imran Abdur Rahim
i used it in my site ( linux server ) .
Eugene
You need ActiveX plugin installed.
Imran Abdur Rahim
will you please make me clear . This plugin is for IE . ok . But is it work in linux server ? I mean i wanna use this file in my site hosted on linux server. possible ?
Eugene
I did not write the solution in the link, merely found the link for you. I don't see why it wouldn't work on a linux server. The only thing I can think is that it may not work on the latest versions of IE as ActiveX was dropped. Give me 5 mins and I'll look a bit further into it.

Here are some resources to get you started.
Writing to a file/directory: http://www.html5rocks.com/en/tutorials/file/filesystem/
Downloading a file: http://html5-demos.appspot.com/static/a.download.html
Downloading a zip: http://stuk.github.com/jszip/
Reading a file: http://www.html5rocks.com/en/tutorials/file/dndfiles/
The top 2 only work in chrome.
jszip has mixed support, and reading files with HTML5 has support in all modern browsers.
It is possible to set the data to a link's href. But a user will have to right click > save link as and add the extension.
<a id="test" target="_blank">click me</a>
document.getElementById('test').href = "data:text/json;charset=utf-8," + escape("Your String goes here");

it just download a file with
part extension. but i need to create a .txt file. possible ?In the browser, no. Server-side (as in node.js), yes.
There is no js function to open a text file from the file system, but you can fetch the contents of a text file on your server with an Ajax request.

I suspect the File API won't do what slash-bang is looking for, as I suspect he wants to do general file IO in pure js, so bfavaretto is right in spirit.

Right, I forgot about the file api. That solves reading local files on modern browsers, but not writing.

+1 good point. But it's possible to open a text file using
XMLHttpRequest on local filesystem.bfavaretto
@metal_fan Is it? I don't think so.
