Html – Browser with HTML5 localStorage for Windows Mobile 6.5

htmllocal-storagemobilewindows-mobile

I know this was asked a year ago but I thought there might be some developments since then. I'm looking for a browser that has support for HTML5 localStorage or Google Gears for the Windows Mobile 6.5 platform. I know Gears is no longer being developed but IMO is still relevant if HTML5 localStorage has not yet hit the WM6 platform. I've tried:

Dorothy browser
Webkit based. Some sites suggest supports localStorage but I've tested on a WM 6.5 emulator and didn't work – maybe only for Android version.

Opera Mini for WM 6.5
Looks like may have some HTML5 support but no localStorage.

Opera Mobile 10
No HTML5 localStorage.

Opera Mobile 9.5beta2
No localStorage but Google Gears local database works (emulator). Problem is it's beta and officially doesn't exist according to Opera – no downloads available, I found it as a forum attachment. Also Opera have announced no more releases for WM.

Internet Explorer Mobile 6
No HTML5 localStorage but Google say it supports Gears, however gears.google.com tells me my browser is unsupported (using emulator), although I believe the useragent is identical to that of a physical WM 6.5 IEMobile6 device.

Best Answer

It seems that Google Gears is supported only up to version 6.0 of Windows Mobile, it is marked unavailable for both IE and Opera (10.0) under Windows Mobile 6.5. I've found no link for Opera 10.5 download for WM, and as for 11, Opera announced it will no longer develop for WM.

R – what are the rules for making mobile friendly website

It's up to you whether you want to make two different websites for mobile and non-mobile devices. However, if you do so, make sure to have a link from the mobile site to the full site to enable users to switch to it.
Opera Mini does support Javascript which certain restrictions (eg. on asynchronous operations). Be aware that Opera Mini uses a proxy based approach and the JS is executed on Opera's servers which imposes certain restrictions. Plugins like Adobe Flash are not supported.
Basically, Opera Mini supports the same standards as Opera Desktop since they share the same rendering engine (Opera Presto). However, due to device restrictions, some features like CSS rounded corners are not available in Mini. See Opera Mini 5 standards support for more information, but know that meanwhile Opera Mini uses Opera Presto 2.4, the rendering engine used in Opera Desktop 10.53.
For testing websites in Opera Mini, try MicroEmulator which is Open Source and comes with a resizable skin that allows you to emulate different screen sizes.

Hope that helps :)

Javascript – Storing Objects in HTML5 localStorage

Looking at the Apple, Mozilla and Mozilla again documentation, the functionality seems to be limited to handle only string key/value pairs.

A workaround can be to stringify your object before storing it, and later parse it when you retrieve it:

var testObject = { 'one': 1, 'two': 2, 'three': 3 };

// Put the object into storage
localStorage.setItem('testObject', JSON.stringify(testObject));

// Retrieve the object from storage
var retrievedObject = localStorage.getItem('testObject');

console.log('retrievedObject: ', JSON.parse(retrievedObject));
