How to copy content of text file into another text file when a button clicked using Javascript?

Question

What I have done so far is a PHP code which is running when the page is refreshed:

<?php
    $pageRefreshed = isset($_SERVER['HTTP_CACHE_CONTROL']) && $_SERVER['HTTP_CACHE_CONTROL'] === 'max-age=0';

    if($pageRefreshed) {
        $file01 = file_get_contents("file01.txt");
        $path = "file02.txt";
        $file02= file_get_contents($path);
        if ($file01!== $file02){
            file_put_contents($path, $file01);
        }
    }   
?>

but, I have an HTML button:

<button class="btn" id="refreshPanel" onclick="refresh_panel()">Refresh Panel</button>

and I want to copy the content of file01 into file02 if this button is clicked using pure javascript.

Both files and .html and .js files stored in the same folder in my computer.

Thanks for your help and time in advance!

How do you plan to run the JavaScript? Node.js? Classic ASP? Cordova? Something else? — Quentin, Oct 06 '17 at 09:05

@maziarser — Would you like it if any website you visited could include a bit of JavaScript and be able to read and write to any file on your hard disk? — Quentin, Oct 06 '17 at 09:23

If you are trying to write a file on client machine, You can't do this in any cross-browser way.

If you want to do something like this, you must pass the execution of these actions to server-side

So, I need to use ajax - for example? – maziarser Oct 06 '17 at 09:08
@maziarser — No. Ajax lets you make HTTP requests. It doesn't let you modify files. – Quentin Oct 06 '17 at 09:24
@Quentin is there any solution to get my issue being solved? – maziarser Oct 06 '17 at 09:30
