jQuery Mobile Tutorial: Creating a Restaurant Picker Web App Mar 08 2012 With an increase in the number, diversity and complexity of smartphones, more and more companies want to have their own mobile app, but creating a native app can be pretty expensive. It requires special skills, as well as special coding tools, and then there is also the need to build an app per platform (Android, iOs, BlackBerry, Windows Phone, etc). All of this figures in to a higher price tag for the app development. The jQuery framework has been around the web for a while now, but the jQuery base technology was basically designed for browser apps. jQuery Mobile is a framework based on jQuery that enables web designers to create web-apps that are optimized for use on a mobile device (Smartphone and tablets). In this jQuery Mobile tutorial, we will create a nice demo app from scratch, to show some of the things that can be easily done using this powerful tool. The Concept of the Mini App: Restaurant Picker Wireframing Our Application. Home Screen : Choose a Plate Choose a Town
Aptana Retina.js | Retina graphics for your website How it works When your users load a page, retina.js checks each image on the page to see if there is a high-resolution version of that image on your server. If a high-resolution variant exists, the script will swap in that image in-place. The script assumes you use Apple's prescribed high-resolution modifier (@2x) to denote high-resolution image variants on your server. For example, if you have an image on your page that looks like this: <img src="/images/my_image.png" /> The script will check your server to see if an alternative image exists at this path: "/images/my_image@2x.png" How to use JavaScript The JavaScript helper script automatically replaces images on your page with high-resolution variants (if they exist). Place the retina.js file on your server Include the script on your page <script type="text/javascript" src="/scripts/retina.js"></script> (put it at the bottom of your template, before your closing </body> tag) That's it!

15. AJAX, Django and JQuery — How to Tango with Django 1.5.4 To make the interaction with the Rango application more seamless let’s add in a number of features that use AJAX, such as: Add a “Like Button” to let registered users “like” a particular categoryAdd inline category suggestions - so that when a user types they can quickly find a categoryAdd an “Add Button” to let registered users quickly and easily add a Page to the Category AJAX essentially is a combination of technologies that are integrated together to reduce the number of page loads. Instead of reloading the full page, only part of the page or the data in the page is reloaded. If you haven’t used AJAX before or would like to know more about it before using it, check out the resources at the Mozilla website: To simplify the AJAX components you can use a library like JQuery. $(document).ready(function() { // JQuery code to be added in here. }); Then in your base template include: 15.1. 15.1.1. 15.1.2. 15.1.3. 15.1.4. 15.1.5. 15.2. 15.2.1.
Using Backbone.js with jQuery Mobile Backbone.js is an architectural framework that helps you write well-structured Web applications. It is not, however, a user interface framework and it therefore doesn’t help you with the way your application looks. Backbone’s confined scope is a good thing: it’s lightweight, non-intrusive, not coupled to things you don’t need, and it lets you use the UI toolkit of your choice or simply roll your own styles and widgets. Quest for a Mobile UI Toolkit After that post, I wanted to create a mobile version of the same application; a version that I could package with PhoneGap and that would look and behave like a native app. Another Way to Use jQuery Mobile jQuery Mobile (jQM) is one option that I’ve explored before (here and here), but it fits more in the category of full-stack frameworks that tie together architectural structure and UI controls and behaviors. Sample Application NOTE: Another approach would be to use jQM’s “routing” instead of Backbone’s. Here is the app: How it works Source Code

Using Virtual Environments in Django At first I was a little hesitant to virtual environments in Django. Not because I didn't think it was a good idea, but because it seemed like a lot of extra work. After finally spending some time learning more about it, I can tell you that overall it is pretty easy and I would highly recommend it for all Django development. Using Virtual environments not only makes rebuilding your environments easier, it also makes deploying to a service such as Heroku or Google App Engine possible. Here is the general workflow I use when dealing with virtual environments. Create environment git clone path-to-github.git new_directory_name cd new_directory_name virtualenv venv All my Django projects have a requirements.txt file saved in the git repository. pip install -E venv -r . Using the Virtual Environment Before starting my development or debugging, I simple open up the command line, navigate to the new folder I created and run: source venv/bin/activate python project_name/manage.py runserver venv *.pyc
jQuery Mobile – Entwicklung einer kleinen Website / App (Tutorial) » Seite, jQuery, Mobile, Website, Kontakt, Attribut » iPhone Entwicklung und Programmierung Ich hatte ja bereits vor einiger Zeit über das Framework “jQuery Mobile” berichtet.

Die Funktionsweise von jQuery möchte ich an dieser Stelle in einem kurzen Tutorial vorstellen. Wer möchte, scheint sich vorab die fertige Beispiel Version an. Bücher zu jQuery Mobile Wer sich nach dem Tutorial etwas genauer mit der Materie befassen möchte und gerne etwas festes in der Hand hat, der hat momentan schlechte Karten. Erste Schritte – jQuery Implementierung Zunächst können die benötigten Dateien (jQuery und jQuery Mobile + CSS) heruntergeladen werden, sofern man diese selber hosten möchte. Wer die Dateien selber hosten möchte, muss hier entsprechend die Links ändern. Rufen wir jetzt die bestehende Seite auf, gibt es leider noch allzu viel zu sehen – bis auf eine leere weiße Seite.

jQuery: Smooth Scrolling Internal Anchor Links | Sycha Web Design & Development November 13th, 2010Charlie Evans Here’s a neat little jQuery trick to fancy up your internal anchor links, by making them scroll smoothly to their target as opposed to jumping instantly. Internal anchor links are very common place, e.g. “back to top” links, or FAQ pages which list all the questions at the top. This is what it looks like in action, click the following link:Scroll to comments This technique is very simple. Set up your link as you normally would, e.g. href=”#comments” (where comments is the id of your target) Add a class=”scroll” attribute to the link element, so it now looks something like this: Finally add the following jQuery code wherever is most appropriate And that’s all there is to it A common mistake in implementing this script is using “named anchors” for your target, instead of an id attribute on your target element.
