var net = require('net');
var server = net.createServer(function(connection) {
console.log('client connected');
connection.on('end', function() {
console.log('closed');
});
// connection.write('100');
connection.pipe(connection);
});
server.listen(5001, function() {
console.log('server is listening');
});
function addInput(){
var value = document.getElementById("textId").value;
console.log(value);
document.getElementById("textId").value="";
//connection.write(value);
}I want to send data to the client in the button function addinput, but I can't send it, how can I use socket.write in the function
Is that code that you commented (connection.write(value);) supposed to work?
You won't be able to make it work since connection is only within the scope of the function you wrote into var server.
Other than that, to get your server to do anything you'll have to make a request to it, possibly with net.createConnection() (check doc here: https://nodejs.org/api/net.html). I'm not seeing any code in your example that would do that so far.
