Javascript / JQuery Save value to file

Question

I have a few radio buttons in a page and I need to save their values or whatever value is selected to a file.

Here is a sample code:

 <input name="select" type="radio" value="a" />
 <input name="select" type="radio" value="b" />
 <input name="select" type="radio" value="c" />
 <input name="select" type="radio" value="d" />

Whenever the user selects one I need it saved / appended into a file.

Possible?

UPDATE:

Tried this:

<script>
  $(document).ready(function () {

$("input[name='select']").change(function(e) {
    e.preventDefault();
    $.post("zzz.html", { selectedValue : $(this).val()  }, function(response) {
        // do something with server response
        alert('saved');
    });
});



});
  </script>

Result: No Result. Nothing created / Nothing Saved.

On the server? On the client? Where?

$("button").click(function(){
    $.post('save_values.php', $("form").serialize(), function(){
             alert('saved');
    });
    return false;
});

If you want to save the the text to a file on your server, then you can use php.

This example checks to see if a file name has been set, and the text to log has also been set. It opens the file and appends text to it by specifying "a+".

So visiting

http://websitename.com/myfile.php?filename=test.txt&log=string to write

Will create and append the text to that file on your server. If then you want to provide the textfile to the user to download you can just use

http://websitename.com/test.txt

This code is untested

<?php
if(isset($_GET["filename"]) == true && isset($_GET["log"]) == true){
    $fp = fopen($_GET["filename"], "a+");

    if($fp !== null){
        fputs($fp, $_GET["log"] . "\r\n");
        fclose($fp);
    }
}
?>

jquery get method

$.get("myfile.php", { filename: "text.txt", log: "string to write" });

Assuming you want to save the selected value every time the radio group has been changed:

$("input[name='select']").change(function(e) {
    e.preventDefault();
    $.post("foo.html", { selectedValue : $(this).val()  }, function(response) {
        // do something with server response
    });
});

If it is on server you can submit to a servlet and open a file and write on the file.

if it is in client side you can try using this jQuery plugin http://jquery.tiddlywiki.org/twFile.html and do that...
