Gettting 0x800a139e - JavaScript runtime error: SecurityError on creating websocket object in .js page

Question

Hi Team,
I am creating a websocket object in the existing webapplication I have. When creating the object with url :    var url = 'ws://localhost:4334//WebSocketServer.ashx?name=Satya'; getting error  . 0x800a139e - JavaScript runtime error: SecurityError.
var ws;
var message ;
var messageVal;
function $(id) {
    return document.getElementById(id);
function wireEvents() {
    $('sendChat').addEventListener('click', function () {
        message = $('message');
        ws.send(message.innerText);
        messageVal=message.innerText;
        message.innerText = '';
    $('btnCancelChat').addEventListener('click', function () {
        ws.close();
function Chat () {
    wireEvents();
    var conversation = $('conversation');
    var url = 'ws://localhost:4334//WebSocketServer.ashx?name=Satya';
    //var url = 'ws://https://127.0.0.1:444/WebSocketsServer.ashx?name=Satya';
    ws = new WebSocket(url);
    ws.onerror = function (e) {
        conversation.appendChild(createSpan('Problem with connection: ' + e.message));
    ws.onopen = function () {
        //conversation.innerHTML = 'Client connected <br/>';
    ws.onmessage = function (e) {
        conversation.appendChild(createSpan(e.data.toString()));
    ws.onclose = function () {
        conversation.innerHTML = 'Closed connection!';
The same works fine if i create a new application i access as a HTML page on page load.
Can any one help me on this?
Thanks,
Satya Chenna
