var socket;
$(document).ready(function () {   socket = new   WebSocket("ws://localhost:1046/socket/handle"); socket.addEventListener("open", function (evnt) { $("#display").append('connection');}, false);    socket.addEventListener("message", function (evnt) { $("#display ").append(evnt.data);}, false);    socket.addEventListener("error", function (evnt) { $("#display ").append('unexpected error.');}, false);  ...  });
Or using straight method calls: function connect(){   try{   var socket;   var host = "ws://localhost:8000/socket/server/start";   var socket = new WebSocket(host);   message('<p class="event">Socket Status: '+socket.readyState);   socket.onopen = function(){   message('<p class="event">Socket Status: '+socket.readyState+' (open)');   }   socket.onmessage = function(msg){   message('<p class="message">Received: '+msg.data);   }   socket.onclose = function(){   message('<p class="event">Socket Status: '+socket.readyState+' (Closed)');    }   } catch(exception){   message('<p>Error'+exception);   }
