Javascript question

PsychoHermit · 10-01-2022, 02:12 PM

Greetings folks,

This isn't really a Linux question so forgive me for posting it but I m stumped and don't know where to turn. I have a web page and am trying to make a hit counter. I have it inside of <script></script> tags. The file count.txt is world writable. Any assistance would be most welcome.

Thanks in advance.

Code:

// Requiring fs module in which
// writeFile function is defined.
const fs = require('fs');

var visitCount = fs.readFile('count.txt');
visitCount = Number(visitCount) + 1;
fs.writeFile('count.txt' visitCount err);
 if (err) throw err;

mods, please move this to the programming forum

Quick example:

hc.html

Code:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>

<body>
    <div>
        <p>The number of visitors is : <span id="cntr">0</span></p>
    </div>

    <script>
    function counter_fn() {
        var counter = document.getElementById("cntr");
        var count = 0;
        count = parseInt(counter.innerHTML);
        count = count + 1;
        counter.innerHTML = count;
    }
    window.onload = counter_fn
    </script>
    
   <button onclick = "counter_fn()"> Reload </button> 
</body>
</html>
