Safari Private Browsing Session Storage
with iOS 7 throws this error. I've been looking around for a resolvant, but considering I'm not even browsing in private, nothing is relevant. I don't understand why localStorage would be disabled by default in iOS 7, but it seems it is? I've tested on other websites as well, but with no luck. I even tried testing it using this website: http://arty.name/localstorage.html, but it doesn't seem like it's saving anything at all for some weird reason. Has quotaexceedederror localstorage anyone had the same problem, only they've had luck fixing it? Should I switch my storage method? I tried hard-debugging it by only storing a few lines of information, but to no avail. I used the standard localStorage.setItem() function to save. javascript iphone html5 local-storage share|improve this question asked Jan 16 '14 at 10:35 NicT 86731020 1 It usually means you tried to store something with a size that exceeded available storage space. What browser are you using (Safari, Chrome, etc.)? Can you share a little more of the code you have been using and if possible the data you're trying to store. –K3N Jan 16 '14 at 21:32 1 This should be considered as a bug or issue on the Safari side. It does not make sense that you can not use localStorage in incognito mode... –Maksim Luzik Feb 1 at 12:09 add a comment| 8 Answers 8 active oldest votes up vote 195 down vote accepted I found the same behaviour on Safari to be caused by private mode browsing. It seems that while on private browsing Safari does not allow local storage to be used at all. The solution for me was to warn the user that the app needs non-private mode to work. share|improve this answer answered May 4 '14 at 7:48 Cristian Dinu 2,009166 2 Your post was just incredibly he

When Safari (OS X or iOS) is in private browsing mode, it appears as though localStorage is available, but trying http://stackoverflow.com/questions/21159301/quotaexceedederror-dom-exception-22-an-attempt-was-made-to-add-something-to-st to call .setItem throws an exception. store.js line 73 "QUOTA_EXCEEDED_ERR: DOM Exception 22: An attempt was made to add something to storage that exceeded the quota." What happens is that the window object still exposes localStorage in the global namespace, but when you call setItem, this exception is thrown. Any calls to .removeItem are ignored. I believe the simplest fix (although I haven't tested this cross browser yet) https://github.com/marcuswestin/store.js/issues/42 would be to alter the function isLocalStorageNameSupported() to test that you can also set some value. currently: function isLocalStorageNameSupported() { try { return (localStorageName in win && win[localStorageName]) } catch(err) { return false } } proposed: function isLocalStorageNameSupported() { try { var supported = (localStorageName in win && win[localStorageName]); if (supported) { localStorage.setItem("storage", ""); localStorage.removeItem("storage"); return supported; } catch(err) { return false } } Of course it's kind of silly to call this every time you want to check that storage is supported, so you could memoize it, but you get the idea. Owner marcuswestin commented Mar 30, 2012 Hi @tjarratt, thanks for the report! You can (and should) check store.disabled. If persistance is not possible and you require it, you should probably display a message saying that the user needs to switch browser or exit private mode. if (store.disabled) { alert('error: storage is disabled') } The check for store.disabled is currently on https://github.com/marcuswestin/store.js/blob/master/store.js#L188. I think I prefer the current implementation since whether the browser supports localStorage or not is a different issue from whether persistance using localStorage is possible on the current webpage. localStorage may be supported but temporarily disabled. Let me know if that addresses your issue, and feel fre
the quota." Safari in Private Browsing on iOS and OSX So apparently Apple didn’t want to (or for undisclosed http://www.mattburkedev.com/dom-exception-22-quota-exceeded-on-safari-private-browsing-with-localstorage/ technical reasons couldn’t) support the WebStorage standard (known as localStorage and sessionStorage) in Private Browsing mode. Other browsers fully support the protocols, with the understanding that at the end of the private browsing session the storage will be wiped clean. As far as I know the feature specification doesn’t define what browsers should do in Private dom exception Browsing, so I suppose its not technically a spec violation. If Apple didn’t want to support it, they should have just not exposed the localStorage or sessionStorage properties on window. Then everybody’s if (window.localStorage) checks would work correctly and we could move on with our lives.1 But instead of doing that, they made it seem like dom exception 22 it was available but instead throw an exception when you try to write to it. Reading just returns null, and remove is apparently a no-op. But as soon as you attempt to write, your page explodes. This is probably half way through some process, making it more difficult to diagnose than necessary. Why expose a broken API? Frequently Asked Questions Why did Apple do this? I don’t know. Care to speculate? Sure. It’s probably some difficulty with their technical implementation that made it difficult to clear the storage at the end of the session. They’re already doing that with cookies, so I doubt it was just the confused orders of some middle manager. How do I reliably feature detect localStorage? You’ll have to attempt a write and catch the raised exception. It’s not enough to just check the existence of window.localStorage. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 function isPrivateBrowsingSupportedEvenIfThisIsSafari() {
