I am having trouble with using OpenLayers in Gmaps4Rails (Gem version 1.5.2.) When I click on a marker I would like to show the typical callout (Infobox). Unfortunately I get the following JavaScript error:
this.serviceObject is undefined
Firebug calls the line 195 of the file "gmaps4rails.openlayers.js" responsable:
return this.serviceObject.addPopup(popup);
If I use Google Maps as API provider instead, everything works fine. Showing and hiding the infobox works nicely. This is why I assume that the error must be somewhere in "gmaps4rails.openlayers.js"
I tried on the latest FF and Chrome on Mac.
For reproducing the error in a reduced example, I created a simple HTML page in the public folder of my Rails 3.2 app and directly linked the needed JS and CSS files. To create the HTML page I copied the HTML code of my broken Rails app and reduced it.

<script type="text/javascript" charset="utf-8">
Gmaps.map = new Gmaps4RailsOpenlayers();
Gmaps.load_map = function() {
Gmaps.map.map_options.provider = "openlayers";
Gmaps.map.initialize();
Gmaps.map.markers = [
{"description":"<p>This shall be in in the popup</p>",
"id":117979030,

"lng":2.64694}
];
Gmaps.map.create_markers();
Gmaps.map.adjustMapToBounds();
Gmaps.map.callback();
};
Gmaps.oldOnload = window.onload;
window.onload = function() {
Gmaps.triggerOldOnload();
Gmaps.loadMaps();
};
</script>
</body>
</html>
Unfortunately I could not find a working example of a successful Gmap4Rails–Openlayers integration on the web. Am I missing a mandatory parameter?
Thanks in advance.
It's a bug.
Replace:
return this.serviceObject.addPopup(popup);
with:
return this.map.addPopup(popup);
I'll push a fix soon, thanks and +1

Just struggling to get the Attach addon working. The main xterm (4.4.0) comes up fine, but the Chrome browser Javascript console reports 'Uncaught TypeError: AttachAddon is not a constructor' when I try to reference the addon. The webserver is golang/echo, and I pull in the xterm.js and xterm-addon-attach.js from the packages as follows:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
<script src="xterm-addon-attach.js"></script>
</head>
<body>
<div id="terminal"></div>
<script>
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://example.net:8080/ws')
const attachAddon = new AttachAddon(ws);
term.loadAddon(attachAddon);
</script>
</body>
</html>
Can anyone help to point out what I've done wrong?
Also the examples in the docs where I took this from doesn't have the term.open() call, so how would the Terminal instance know what element to attach to? Eg at https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-attach
Many thanks in advance
Andy
Update:
I changed the HTML to include the import statements, as follows:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
</head>
<body>
<div id="terminal"></div>
<script type="module">
import { AttachAddon } from "./xterm-addon-attach.js";
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://boundstone.dynamic-dns.net:8080/ws');
const attachAddon = new AttachAddon(ws);
term.loadAddon(attachAddon);
</script>
</body>
</html>
but the Chrome console now reports: "The requested module './xterm-addon-attach.js' does not provide an export named 'AttachAddon'". The webserver serves the script with content type application/javascript, and the Chrome console recognises the structure of the AttachAddon as a Webpack it seems.
I'm afraid I'm not familiar as I clearly should be with JS modules. The web server for my project is not (and can't be) Node, but does that make a difference?
Many thanks in advance
Andy
This is what worked for me. The only thing you have to do is use AttachAddon twice as shown below using the OP's example. That's the only trick to getting it working. I am also using the fit addon and it was the same thing with that.
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
</head>
<body>
<div id="terminal"></div>
<script>
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://boundstone.dynamic-dns.net:8080/ws');
const attachAddon = new AttachAddon.AttachAddon(ws);
term.loadAddon(attachAddon);
</script>

I am trying to build a small mobile app with JQuery Mobile and EmberJS.
This is actually a Rhodes Application (Rhomobile).
This is my Layout.erb:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Todo</title>
<!-- Ember Libraries -->
<script src="/public/js/libs/handlebars-1.0.0.js"></script>
<script src="/public/js/libs/ember.js"></script>
<script src="/public/js/libs/ember-data.js"></script>
<!-- Ember Application -->
<script src="/public/js/application.js"></script>
<script src="/public/js/router.js"></script>
<script src="/public/js/models/todo.js"></script>
<script src="/public/js/controllers/todos_controller.js"></script>
<script type="text/javascript">
$(document).bind("mobileinit", function(){
$.mobile.loadingMessage = false;
$.mobile.loadingMessageDelay = 300; // in ms
$.mobile.defaultPageTransition = 'none';
$.mobile.defaultDialogTransition = 'none';
$.mobile.ajaxEnabled = false;
$.mobile.pushStateEnabled = false;
$.mobile.loadingMessageDelay = 50; // in ms
});
</script>
<link rel="stylesheet" href="/public/jqmobile/jquery.mobile-1.3.1.min.css">
<link rel="stylesheet" href="/public/css/jqmobile-patch.css">
<script src="/public/jqmobile/jquery.mobile-1.3.1.min.js"></script>
<script src="/public/js/jqmobile-patch.js"></script>
</head>
<body data-platform="<%= Rho::System.getProperty('platform') %>">
<%= #content %>
</body>
</html>
As you can see I have disabled Ajax and PushState and stuff. This is my index.erb:
<script type="text/x-handlebars" data-template-name="todos">
<div data-role="page">
//My Template
</div>
</script>
Now when I try it, I just get a blank grey page. But no error in console or in Ember-Console (extension of Chrome). It even detects my views and controllers properly.
Then I try commenting the JqueryMobile CSS files and what I get is a page's height worth of blank space with "Loading" message and then I see my application below and it works fine. And if I remove JqueryMobile JS, I get the stuff but its not styled.
What is the problem?
It's kind of hard to say without seeing some more code of your app. If you only have the one template defined ('todos') it may be the case that Ember doesn't know how to kickstart the rendering of your app. You may need to define an 'application' template. It might be as simple as:
<script type="text/x-handlebars" data-template-name="application">
{{outlet}}
</script>
when I tried to run even a blank app, the console output is:
"Error calling js to fire nativeReady event. Did you include cordova.js in your html script tag?"
Doctype is:
<!DOCTYPE html>
And this are script references:

This error disappears only when I remove the jquery mobile stuff...
Thanks in advance.
I would avoid JQuery Mobile in PhoneGap applications. I got to meet Andrew Trice, Adobe PhoneGap Evangelist, at a DC Droid Meet and listened to him present in a few Webinars. I've heard him say more than once that JQuery Mobile has huge performance issues. He recommended using other frameworks if possible. There are many other frameworks out there with good design, widgets, and samples that make them easy to learn. I think he even created his own called AppUI. Just look around and you'll find some really cool ones.
That error is definitely what it says: your cordova.js file is not being included correctly. Fix that first.
To answer your larger question: Angular, jQuery Mobile, and PhoneGap will play together but it comes with some big caveats.
The biggest issue is that the jQuery Angular Mobile adapter is currently abandoned while they invest time in building a better solution: angular-jqm. That means that the adapter only works with outdated versions of the libraries.
Second: those outdated library versions have some issues working with Windows Phone. These are fixable, too, but lock you into an even less maintainable version of them.
So here is the setup:
<script src="javascripts/vendor/jquery-mobile-1.3.1.js"></script>
<!-- this angular-1.0.6 includes a patch to support WP8 URLs: https://github.com/angular/angular.js/issues/2303 -->
<script src="javascripts/vendor/angular-1.0.6.js"></script>
<script src="javascripts/vendor/jquery-angular-mobile-adapter-1.3.2.js"></script>
Unfortunately I was never able to get partials to load via XHR so I included all pages in index.html document.
<body ng-controller="AppController">
<div data-role="page" id="first" ng-controller="FirstController">
<h1>First Page</h1>
<p>{{foo}}</p>
<p>Second Page</p>
</div>
<div data-role="page" id="second" ng-controller="SecondController">
<h2>Second Page</h2>
</div>
</body>
Then you need to switch off a few niceties in the JavaScript and set up your routes:
<script>
var so_example = angular.module('so_example', []).
config(function ($routeProvider, $locationProvider, $compileProvider) {
// turn off html5 mode so that we just navigate around using hashes
$locationProvider.html5Mode(false).hashPrefix("");
// allow for the odd URLs included in Windows Mobile PhoneGap
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel|x-wmapp0):/);
$routeProvider.
when('/second', {
templateUrl: '#second',
jqmOptions: { transition: 'slide' }
}).
when('/', {
templateUrl: "#first"
});
}).
controller("FirstController", function ($scope) {
$scope.foo = "Hello, World!";
}).
controller("SecondController", function ($scope) {
});
</script>
Now you need to leverage the Cordova library before you bootstrap Angular to your HTML:
var app = (function () {
function onDeviceReady() {
angular.bootstrap(document, ['so_example']);
$.mobile.phonegapNavigationEnabled = true;
}
return {
initialize: function() {
document.addEventListener('deviceready', onDeviceReady, false);
}
};
})();
app.initialize();
I have a phone gap application with jquery mobile and I can get external links to work and single page navigation working but I cannot open another file in my application. All the files are located in the www folder. The error message is "Failed to load webpage with error: The requested URL was not found on this server. If i comment out the jquery-1.6.4.min.js file it will work but that's not a good solution. I've tried rel="external" and several other things I've seen by googling but nothing seems to work

<script type="text/javascript" charset="utf-8" src="phonegap-1.3.0.js"></script>
<script type="text/javascript">

{
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady()
{
//do something
}
</script>
</head>

Make sure that you update your PhoneGap manifest. Look for PhoneGap.plist, open it and look for ExternalHosts. You need to add the urls one by one, or you can simply add "*". This will allow the use of all urls within the application. PhoneGap blocks all urls by default.
I have started a new ASP.NET MVC project and have included the ExtJS library files. This all works fine when built from Visual Studio and i can display various ExtJS objects. The problem however is that FireBug has stopped showing errors in the Console, even when i type nonsense into the code block.
Setup is:
VS 2008 SP1
FireBug 1.4.2
FireFox
3.5.2
Firebug is working with other public web sites and when viewing other PHP based sites I'm developing.
Does anyone have any ideas what might be causing this?
Thanks for any suggestions
Stuart
Thought i would give some more info...
