jQuery HTML5 Websocket or AJAX Chat: jQuery Chat plugin using Websockets or AJAX

Code to initialize object:
var ms = new $('#msgchat').jqh5ajx({ msg_link:server_url, clbk_fnc:'setchatdtls' });

where server_url is the server url to call, and setchatdtls is the callback function. 

Code to send data using websocket:
// use this condition to make sure it is using websocket connection
if(typeof ms.mcevs != 'undefined' && ms.mcevs != null && typeof ms.chattype != 'undefined' && ms.chattype != null && ms.chattype == 'ws') {
    ms.send('text');

// use this condition to make sure it is using websocket connection
if(typeof ms.mcevs != 'undefined' && ms.mcevs != null && typeof ms.chattype != 'undefined' && ms.chattype != null && ms.chattype == 'ws') {
    ms.close();
