Is Safari on iOS 6 caching $.ajax results?
$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
// you can use originalOptions.type || options.type to restrict specific type of requests
options.data = jQuery.param($.extend(originalOptions.data||{}, {
timeStamp: new Date().getTime()
}));
});
iOS6 Safari orientation change bug?
Safari Overflow Hidden Problem
There may be times when you need to hide the overflow (scrollbars) being visible on a page. You can specify to have all scrollbars hidden or the x and y scroll bars separately. When trying to hide the overflow of a project I was working on I realized that the ‘overflow:hidden’ was not working on the Safari browser. This was very frustrating because it worked on all other browsers except Safari. Well, there is a very simple solution to solve this problem… All you have to do is set that element to have a relative position. For instance, if you were to specify for the body to hide the horizontal scrollbars you would want to have the following css in your stylesheet:
body { position:relative; overflow-x:hidden; }
iOS 6 Beta 1: HTML5 new APIs, Remote Debugging and native apps integration
Public new features for Safari on iOS 6
File uploads
Finally! We can now select an image from the Photo Library or opening the Camera from a web form. The question is about HTML Media Capture being implemented or not (see later for the answer).
Web Audio API
With the Web Audio API we can enhance HTML5 games and multimedia apps with mixing, filtering and processing operations through JavaScript.
CSS Filters
CSS 3 Filters a set of image operations (filters) that we can apply using CSS functions, such as grayscale, blur, drop-shadow, brightness and other effects. These functions will be applied before the content is rendered on screen. We can use multiple filters using spaces (similar to transforms).
Smart App Banners
It’s a way to connect websites to native applications. When you browse a web that has a related native application, Safari can show a banner inviting the user to install or open the native app. The website can also send parameters to the native app. It’s not clear how this is going to be implemented. My guess is through meta tags. The same behavior is available on Internet Explorer 10 for Windows 8.
Full Screen support on landscape
When you orient your device in landscape mode you can then move to a full-screen mode, including hiding the status bar and the Safari toolbar at the bottom. Transparent buttons are replacing the toolbar. A similar behavior is available on Nokia Browser for Symbian. It’s not clear at this point if we can use the FullScreen API to request the feature (see later for the answer)
Remote Web Inspector
This is a big feature. Announced as a very small feature in the new APIs for developers. In the keynote there was no other information. As you may know, I’ve developed iWebInspector for iOS 5 because of the lack (or the hiding) of a web inspector tool for debugging web apps. It’s not public if this new Remote Web Inspector through LAN (like BlackBerry Remote Web Inspector) or through USB (like Google Chrome for Android)… the answer, later in this post.
Crossfade CSS Function
This feature was published in the keynote with “font-face: 3px” but I’ve seen it. It’s an image function that will create a crossfade between two images (Spec draft), for example:
1.background-image: -webkit-cross-fade(url("image1.png"), url("image2.png"), 40%);Will it work with transitions?
Other announced features and questions
iCloud Tabs
You can synchronize your tabs between all your devices, including Macs, iPhones and iPads. So the same URL will be distributed through all devices. Be careful on your mobile web architecture!
Offline Reading List
when the user adds a page to the reading list it will be also downloaded and precache. Is there any API to know if our page is being executed from the cache?
Maps
Google Maps native app was replaced by a new Maps app (directly from Apple). The question is, is this app still capturing http://maps.google.com URLs? (I hope not) and how to open the native app or driving instructions from a web.
Twitter and Facebook
Both social networks are not integrated in the operating system. It will be good if at some point web apps can also use these credentials.
Questions from the past
WebGL? IndexedDB? getUserMedia (camera access)? Nitro engine on Web Views?
