สอบถาม websocket connect ip ได้ แต่ domain name ไม่ได้

const socket = new WebSocket('ws://localhost:8080');

function webSocketSupport() {
        if (browserSupportsWebSockets() === false) {
            $('#ws_support').html('<h2>Sorry! Your web browser does not supports web sockets</h2>');
            $('#wrapper').hide();
            return;
        }

        // Open Connection
        // socket = new WebSocket('ws://ip:8089');
        socket = new WebSocket('wss://domaim.com:8089');

        socket.onopen = function(e) {
            $('#connect').html("ONLINE<br><br>");
        };

        socket.onmessage = function(e) {
            //
        };

        socket.onerror = function(e) {
            onError(e)
        };

    }

    function onError(e) {
        alert('Error');
    }

var exampleSocket = new WebSocket("wss://www.example.com/socketserver", "protocolOne");
