local-storage

问题 I need to increase the default quota limit of the LocalStorage in a Android WebView. Currently I can only use around 2.5MB. When trying to store more data, a quota_exceeded_err (dom exception 22) is raised. Any ideas or do I have to switch to db/file system ? 回答1: We're talking about HTML5 WebStorage DOCS There is plenty of question on the same theme, only not Android-specific HTML5 localStorage size limit for subdomains What is the max size of localStorage values?

问题 I just get a strange bug when using those two tools. I'm making an AJAX query to an API, then retrieving JSON data which is stored within localStorage and displayed into an autocomplete panel. The problem is that according to the origin of the autocomplete source, the panel will react differently. Here is the callback function called on AJAX success : function _company_names(data) { localStorage.setItem('ac_source', JSON.parse(data).Result); // Works fine $("#search_input").autocomplete(

问题 So I've run into a bit of snag with regards to local storage on Google Chrome. From what I've researched, my syntax seems to be correct, but for some reason the value is not being saved. Here's my code: chrome.storage.sync.get(accName, function(data) { var accData = data[accName]; // Stuff chrome.storage.sync.set({ accName: accData }, function() { alert('Data saved'); }); }); Every time I re-run it, data[accName] returns undefined. I've tried the same code with literal values for the sync.set

问题 I'm developing a web app for iPad (3G) that requires offline database storage. At first I tried using HTML5's LocalStorage API. When testing, I learned that if I navigate away from the page and power off the device (both iPad and iPhone), when I reopen the page later, my data cannot be accessed via LocalStorage (database appears to be missing). I see this behavior at http://diveintohtml5.ep.io/examples/localstorage-halma.html with iOS devices, but Android devices (Droid X and Galaxy) and a PC

问题 I want to store JSON data in local storage. Sometimes data stored could be more than 5MB(max threshold allowed by browsers for each domain).

I am using this json data to display on webpage..... It is like a static data which is mostly same for entire session. we provide actions like search, filter etc on this json

问题 I have indexedDb on my app for web storage. I would like to get the store form the below code. var store = myapp.indexedDB.db.transaction(['tree_nodes'],'readwrite').objectStore('tree_nodes'); It returns error.

In that case it works fine without errors. How can i get the store? please help me. Thanks in advance! 回答1

问题 I'd like to add 2 methods to localStorage. My goal is to end up with something like this: localStorage.setObject(key, object); localStorage.getObject(key); This solution works in most browsers but not IE8: Storage.prototype.setObject = function(key, value) { this[key] = JSON.stringify(value); } Storage.prototype.getObject = function(key) { return JSON.parse(this[key]); } After doing some research, apparently I could use Lawnchair.js or work around it some other way. But I'm wondering why it

问题 I have some div's on my page coded as <div id="1">Click Me to load corresponding dynamicList</div><ul class="dynamicList"></ul> <div id="2">Click Me to load corresponding dynamicList</div><ul class="dynamicList"></ul> <div id="3">Click Me to load corresponding dynamicList</div><ul class="dynamicList"></ul> <div id="4">Click Me to load corresponding dynamicList</div><ul class="dynamicList"></ul> <div id="5">Click Me to load corresponding dynamicList</div><ul class="dynamicList"></ul> Now on

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);
