My console is not showing a simple log from below angular code.
I am getting a 304 Not Modified error in Firefox.
My HTML has the myApp and mainController defined and used.
var myApp = angular.module('myApp', []);
myApp.controller('mainController', function($scope) {
$scope.name = 'Name';
console.log($scope.name);
});
Any ideas what is going on here?
Edit - here is the HTML code:
<!DOCTYPE html>
<html lang="en-us" ng-app="myApp">

Has your console.log statement always been in your code? Or have you just added it?
If it's the former, then I'm not sure what's happening. Sorry.
If it's the latter, then it sounds like Firefox is loading a cached version of your file that doesn't include your console.log statement. In fact a response with a HTTP status code of 304 Not Modified isn't an error. It is the server telling the browser that the requested resource hasn't changed, so you can load your cached copy.
Try clearing Firefox's cache, or reloading using Ctrl + shift + R or Cmd + shift + R to override the files in the cache.

Hi im currently creating a small app that uses bootstrap and jquery and im having a little problem regarding importing the css and js files.
this is my layout.erb looks like.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Portfolio</title>
<link href="public/css/bootstrap.min.css" rel="stylesheet">
<script src="public/js/bootstrap.min.js"></script>
<script src="public/js/jquery-3.1.0.min.js"></script>
</head>
<body>
<header>
<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<ul class="nav navbar-nav">
<li>Home</li>
<li>Projects & Tutorials</li>
<li>The Division Highlights</li>
<li>Contact Us</li>
</ul>
<p class="navbar-text navbar-right"><span class="glyphicon glyphicon-user"></span> Login / Signup</p>
</div>
</nav>
</header>
<section>
<%= yield %>
</section>
<footer>
<div class="panel panel-default">
<div class="panel-footer">© Copywrite JDG</div>
</div>
</footer>
</body>
</html>
here is where i configure the files for my views folder
require 'rubygems'
require 'sinatra'
require_relative './app'
module Portfolio
class MainRoutes < Sinatra::Base
before do
#user_authentication = Portfolio::Main
end
configure do
set :views , File.expand_path('../../../Portfolio-FE/views', __FILE__)
set :root , File.dirname(__FILE__)
end
helpers do
include Rack::Utils
alias_method :h, :escape_html
end
get '/' do
erb :index
end
end
end
and this is what my Files looks like.
the css and js is not being imported in the project and i wonder why.
thanks guys.
I figured out the answer,
Just set the public folder like this:
set :public , File.expand_path('../../../Portfolio-FE/public', __FILE__)
and import the files like this.
<link href="css/bootstrap.min.css" rel="stylesheet">
<script src="js/bootstrap.min.js"></script>
<script src="js/jquery-3.1.0.min.js"></script>
Apart from setting the public folder, you might want to use Sprockets.
I have an example app here: https://github.com/katgironpe/simple-sinatra-mvc
http://www.sinatrarb.com/configuration.html
set :root, File.dirname(__FILE__)
set :public_folder, Proc.new { File.join(root, "static") }
Follow the official guides. Don't forget to set root of your app.
I was trying out David Sulc's gentle intro to Marionette.js (Backbone.js) In almost the very first exercise, I encounter a strange problem. When i run the code in chrome or firefox,i see no error in console but apparently the application has not yet started (otherwise, the text rendered by marionette should have been visible). Similarly, the "console.log" command is showing no response in the console window. Console is absolutely blank. no errors, no warnings. please help.
Here's the code. Please let me know what exactly I'm doing wrong.
<!DOCTYPE html>

console.log("ContactManager has started!");
var staticView=new ContactManager.StaticView();
ContactManager.mainRegion.show(staticView);
});
ContactManager.start();
</script>
</body>
</html>
I believe that you are mixing up the syntax for two different versions of Marionette.
If you're using start(), try:
ContactManager.on("start", function(){});
According to the docs, events are:
"before:start" / onBeforeStart: fired just before the Application starts and before the initializers are executed.
"start" / onStart: fires after the Application has started and after the initializers have been executed.

I'm using JQuery Mobile, and now I would like to navigate through pages with the minimum of loading amount of scripts everytime a page is being loaded, I mean that I would like to import only ONCE all the general scripts of all the pages (JQuery.js, jquery_mobile.js, main.js etc...) and
So I have an index.html with the following code :
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">
<title>Hybrid App</title>
<link rel="stylesheet" href="jqueryMobile/jquery.mobile-1.4.4.css" />
<link rel="stylesheet" href="jqueryMobile/jquery.mobile.icons-1.4.4.css" />
<link rel="stylesheet" href="css/jquery.mmenu.css" />
<link rel="stylesheet" href="css/main.css" />
<script>window.$ = window.jQuery = WLJQ;</script>
<script type="text/javascript" src="js/jquery-2.1.1.js"></script>
<script type="text/javascript" src="jqueryMobile/jquery.mobile-1.4.4.js"></script>
<script type="text/javascript" src="js/jquery.mmenu.min.js"></script>
<script type="text/javascript" src="js/initOptions.js"></script>
<script type="text/javascript" src="sharedResources/customersObject.js"></script>
<script type="text/javascript" src="js/main.js"></script>
<script type="text/javascript" src="js/messages.js"></script>
</head>
<body style="display: none;">
<div data-role="page" id="page">
<link rel="stylesheet" href="css/pages/splash-view.css" />
<div data-role="header" id="header" data-position="fixed"></div>
<div data-role="content" id="pageContent">
<div id="splash-wrapper">
<div class="splash-content">
Login
</div>
</div>
</div>
<div data-role="footer" id="footer" data-position="fixed"></div>
<nav id="menu">
<ul data-role="listview" data-inset="true">
<!-- list of items in the slide sidebar menu (called drawer menu in Andorid -->
</ul>
</nav>
<script src="js/pages/splash-view.js"></script>
</div>
</body>
so when clicking on the link I go to an external HTML file located in : pages/faqs-view.html with the following code :
<div data-role="page" id="page" data-url="pages/faqs-view.html">
<link rel="stylesheet" href="css/pages/faqs-view.css">
<div data-role="header" id="header" data-position="fixed"></div>
<div data-role="content" id="pageContent">
<div id="faqs-wrapper">
<div class="faqs-content">
<div data-role="collapsible-set" data-corners="false" data-collapsed-icon="arrow-r" data-expanded-icon="arrow-d" id="faq-set">
</div>
</div>
</div>
</div>
<div data-role="footer" id="footer" data-position="fixed"></div>
<nav id="menu">
<p class="employee-name">Welcome, Ali</p>
<ul data-role="listview" data-inset="true">
<!-- list of items in the slide sidebar menu (called drawer menu in Andorid -->
</ul>
</nav>
<script src="js/pages/faqs-view.js"></script>
The problem is that when loading the faqs-view.html page, I can see that none of the scripts included in the <head> are being executed, I have tried to put them after the <body> tag, but it's the same, BUT the CSS files are being interpreted.
How can I achieve that ? Thank you.
Worklight-based applications are Single Page Applications. This means you should never navigate away from the index.html. Doing so will cause the app to lose its context to the Worklight framework, thus it will begin to fail.
If you'd like to add multi-page navigation to the application, you can do so using the API provided by 3rd-party frameworks. Here you are using jQuery Mobile.
You've changed the loading order of scripts. You shouldn't.
Use the Worklight Studio wizard in order to create an app template with jQuery Mobile (new project > new hybrid application (click on "configure javascript libraries" > select the library you would like to add))
Keep initOptions.js, main.js and messages.js where they are by default, at the bottom
The index.html you get is your template with jQuery Mobile
If you want to replace the bundled jQuery, you need to comment out (slide #6) the following script tag: <script>window.$ = window.jQuery = WLJQ;</script>. Worklight is bundled with jQuery 1.9.x.
For a bare-bones example of multi-page navigation in a Worklight-based application, using jQuery Mobile, take a look at this project.
As you navigate between pages, you only replace the contents of the data-role="page". The scripts have already been loaded. You can load additional scripts per where required when loading a specific page.
They are executed in the order you put them on the page.
window.$ = window.jQuery = WLJQ;
Cannot be executed before jQuery is included.
Edit:
When you load a new page without the header it's clear that it won't be excecuted because it is not there.
When you replace html in your page you should look at the "on" function for events.
I am trying to build my first project for iOS using PhoneGap. I have picked up an example from this page:
http://www.codeproject.com/Articles/579532/Building-an-iPhone-App-using-jQuery-Mobile
And my code looks like this after changing reference to 1.4.1 ans 1.9:

This page, if you copy to an html file will display formatted text. However when I copy the App to iPhone it displays simple text.
Can someone please tell me what I am doing wrong?
I think I have just solved the issue.
I made a reference to cordova.js in main html file. And as a precaution copied cordova.js to www folder. And the text started appearing formatted the JQM way.
I'm starting out with Angular and am running in to problems. I'm not sure I am understanding how module dependencies work.
When creating a module, you pass in an array of required modules (that contain services), right? And when you actually use a controller in that module, you pass it a service function defined in one of your required modules.
This is the error I am encountering in my application:
Failed to instantiate module MyApp due to:
Error: [$injector:modulerr]

I define my service modules like this:
var MachineServices = angular.module('MachineServices', ['http']);
MachineServices.factory('Rest', function($http){
return{
//get machine from server
//save machine to server
//delete machine from server
//get machine list from server
}
});
In setup.js, after the modules with services are loaded, I create my main module:
var MyApp = angular.module('MyApp', ['ngRoute', 'ngAnimate', 'CustomerServices', 'InspectionServices', 'MachineServices']);
There is something wrong with the way these modules and their containing services are created. When I remove them as dependencies I no longer get an error.
What am I missing here?
Thanks in advance.
I think your problem is likely within your module definition:
var MachineServices = angular.module('MachineServices', ['http']);
You don't need to depend upon http. The $http service is part of the Angular core, so it is not a module you need to import. Doing so will give you an error.
I should also correct you on your use of "Services" and "Modules" interchangeably. A module is a collection of factories, services, directives, controllers, filters, etc that can be injected into other modules to use. "Service" has a specific meaning in Angular and is more granular than "Module".
