Disclaimler: First of all, let me state clear that I am not involved into the Framework7 project. I am not getting paid for this post. This is just my honest, personal opinion as a mobile developer. Early steps The first framework I used when I started mobile development was jQueryMobile. I was used to jQuery […]
If you’re European like me, you’re probably used to this notation: € 366.432 instead of 366,432 or 366432. In order to get this done in JavaScript you want to do the following: // Number var money = 366432; // Convert to String and add dots every 3 digits var moneyDots = money.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, “$1.”); // Set […]
The problem in Framework7 In most webapps for iOS (not only Framework7) that use -webkit-overflow-scrolling:touch for scrolling within elements instead of the whole body you will experience the following issue: You scroll up to the very top of the document and then you scroll down immediately when you get the bounce back. You will notice […]
I wanted to create a similar experience to those cards that you can swipe left and right in Tinder, but with web technology. So I did. There are already 2 libs that do this but they’re based on Ionic which I didn’t want to have a dependency on. Tindercards.js only requires jQuery and Hammer.js. The […]
If you created a website with 100% height, you might encounter the problem that iPhone5 doesn’t hide the address bar while iPhone 4/4s and older do hide it. Existing solutions There are quite some JavaScript-based solutions on this issue that use scrollTop() and add a margin at the bottom of your page, e.g.: Hide address […]
It’s really simple, just use this function: function isIphone5(){ function iOSVersion(){ var agent = window.navigator.userAgent, start = agent.indexOf( ‘OS ‘ ); if( (agent.indexOf( ‘iPhone’ ) > -1) && start > -1) return window.Number( agent.substr( start + 3, 3 ).replace( ‘_’, ‘.’ ) ); else return 0; } return iOSVersion() >= 6 && window.devicePixelRatio >= 2 […]
Update: This post may still be correct but since ES6 the keyword “class” has been introduced to JavaScript, so make sure to check this out first: ES6 classes The following is a personal best practice advice for OO with ES5 (and older) Coming from a Java background, I really miss keywords like class or extends […]
I’ll be speaking on the upcoming ZK user group conference in Mannheim, Germany on December 6th, 2011 (what’s ZK?). If you enjoy developing rich internet applications with the power of Java, I highly recommend to be there. If you want to join, just sign up for the event on zkoss.org for free and see three […]
Here we have an interesting Flash2HTML5 converter which seems to work up to (parts of) Flash8. Check out smokescreen.us for demos and more info (Thanks to Antonio for the link). Seems like it works pretty decently regarding movies and animations but I wonder if “real” applications would work with it, like for example such which […]
I am currently writing my diploma thesis at the University of Ulm on performance issues regarding Rich Internet Application technologies like Adobe Flash/Flex, JavaFX, Silverlight and various JavaScript solutions. (Update: It’s done! :-) ) I started back in December when I first noticed that Adobe’s Flash Player seriously has some performance issues. It always was […]
