I'm starting with Node.js and I have already a problem in my first program. Below is the code I'm using. Index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Random Temperatures</title>
</head>
<body>
<input type="text" id="tb" name="tb" />
<input type="button" value="Random Number!" id="myButton" name="myButton"/>
<script src="client.js"></script>
</body>
</html>
Client.js:
const textBox = document.getElementById('tb');
const button = document.getElementById('myButton');
button.addEventListener('click', function(e) {
var rnd = Math.floor(Math.random() * 100);
textBox.value = rnd;
});
Server.js:
var app = require('http').createServer(response);
var fs = require('fs');
app.listen(8080);
console.log("App running…");
function response(req, res) {
fs.readFile(__dirname + '/public/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Failed to load file index.html');
}
res.writeHead(200);
res.end(data);
});
}
When I start the application I go to the browser the text box and the button appear. But in the browser console I'm getting these errors:
client.js:1 Uncaught SyntaxError: Unexpected token <
ContentScript.js:112 Exception in onResRdy: TypeError: Cannot read
property 'htmlRes' of undefined
localhost/:1 Unchecked runtime.lastError: Could not establish
connection. Receiving end does not exist.
I guess my problem is the linking between the 3 files but I tried several things and I can't solve the problem. I'm sure it's a stupid error but forgive me I'm just getting start. Any advice?
