local-storage

问题 I have a localStorage item named as "1" and containing "something". I want to change the name to "2" and leave the contents intact. How can I do that? I know that I can copy the entire contents to "2" and then delete "1" but is there any other direct method? 回答1: You can take a look at the official specification. The storage interface looks like this: interface Storage { readonly attribute unsigned long length; DOMString? key(unsigned long index); getter DOMString getItem(DOMString key);

问题 I am developing an HTML5 app specifically for Android and Chrome . The problem I have stems from the requirement to track open browser tabs. I do this by creating a unique ID stored in each tab's sessionStorage. I then track the open tabs by registering each ID in a localStorage array that each tab has access to. The problem is that I cannot remove the ID from localStorage when closing a tab by using the window.onunload event. The code works fine in desktop Chrome but I cannot get it working

问题 I want to listen for changes that are happening in the localStorage API on the same page (Not in multiple tabs like the spec says). I am currently using this code: var storageHandler = function () { alert('storage event 1'); }; window.addEventListener("storage", storageHandler, false); localStorage.setItem('foo', 'bar'); Does anyone know a vanilla JavaScript way to listen to events on localStorage on one page (no jQuery) 回答1: Since JS is dynamical language just rewrite original functions. var

问题 I'm developing a hybrid app (for iOS and Android only) using PhoneGap/Cordova and want to use HTML5 localStorage to store content for offline access. http://caniuse.com/#search=localStorage says - "In iOS 5 & 6 localStorage data is stored in a location that may occasionally be cleared out by the OS."
