angularjs - ReferenceError: io is not defined - when socket server is different than localhost -


a lot of questions same title 1 different not find in existing stack overflow collection.

i have socket server @ different host , want use socket server web app.

i tried use inside index.html file of angular application way: index.html

<head> <link rel="stylesheet" href="onecss.css"> </head>  <body ng-app="myapp"> <div ui-view></div> <script ng-href="{{socketurl}}"></script> <!-- $rootscope.socketurl = "https://example.com/socket.io/socket.io.js"; --> <script src="bower_components/angular-socket-io/socket.js"></script> <script src="commsocket.js"></script> <script src="onejs.js"></script> </body>

commsocket.js

(function(app) {     'use strict';     app.factory('commsocket', function (socketfactory) {         var socketurl = "https://example.com";         var iosocket = io.connect(socketurl); // here io throws error. referenceerror: io not defined         var options = {             iosocket: iosocket         };         var socket = socketfactory(options);         socket.forward('broadcast');         return socket;     }); })(app);

i think time https://example.com/socket.io/socket.io.js loads, commsocket gets called before , throws error. question how can wait socket.io.js file load before commsocket gets called.

this works fine if connect local socket.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
