I'm trying to take input from a form and save it into a text file that is in the same folder as the html file. This is what I have so far:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Reservation</title>
<meta name="description" content="The HTML5 Herald">
<meta name="author" content="SitePoint">
<link rel="stylesheet" href="css/styles.css?v=1.0">
<script>
function writeToFile(item, name, time)
{
alert("Hello " + item);
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.OpenTextFile("E:/labChart/etc/reserve.text", 8);
fh.WriteLine(item);
fh.Close();
}
function readFile()
{
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.OpenTextFile("reserve.text", 1, false, 0);
var lines = "";
while (!fh.AtEndOfStream) {
lines += fh.ReadLine() + "\r";
}
fh.Close();
return lines;
}
</script>
</head>
<body>
Reservation
<br>
<form>
Item:
<br>
<input type="text" name="item" id="item">
<br>
Name:
<br>
<input type="text" name="name" id="name">
<br>
Time:
<br>
<input type="date" name="time" id="time">
<br>
<br>
<input type="submit" value="Submit" onclick="writeToFile(document.getElementById('item').value, document.getElementById('name').value, document.getElementById('time').value)">
</form>
<script src="js/scripts.js"></script>
</body>
</html>This does take the info from "item" and pass it to the function writeToFile() because the test alert does work. But whenever I check the file reserve.text nothing is written there. I'm very new to javascript and most of this is an amalgamation of code I saw other people using online for similar effects. Does anyone know why it is not working? Am I writing the path incorrectly? Am I not writing the script correctly?

There is a built-in Module or in-built library in NodeJs which handles all the writing operations called fs (File-System). It is basically a JavaScript program (fs. js) where function for writing operations is written. Import fs-module in the program and use functions to write text to files in the system.
The easiest way to write to files in Node. js is to use the fs. writeFile() API.
JavaScript Display Possibilities Writing into an HTML element, using innerHTML . Writing into the HTML output using document.write() . Writing into an alert box, using window.alert() . Writing into the browser console, using console.log() .
readFile() and rs. writeFile() methods are used to read and write of a file using javascript. The file is read using the fs. readFile() function, which is an inbuilt method.
The problem with this is simple: Lets say a developper created javascript code to go through all your filesystem and populate it with dummy files, ruining your hard drive in the process? That is why javascript won't allow you to do this kind of operation. When we want to save information, usually, its done using server-side code and not the client's computer (unless of course we are talking about things like cookies).
The point of my answer is to let you rethink who does the saving and to where. It should be up to the server to save and retain any information for a user, and so you would not write this kind of javascript code... It is best to save data somewhere your client cannot control or edit, like on the server for instance.
I could suggest some easy PHP code, and instead of storing inside a text file, try a database... PHP is a server-side language which will let you save things to files on your server computer, however your server must be able to run PHP, most computers don't come built in with the PHP language and so you will also need a webserver with php built-in..
