local-storage

问题 I'm facing a problem with phonegap cookie based authentication: After i force the iPhone to close my app (double click on the physical button and close), i lose the cookie that i established with the server.

I'm using: iPhone - iOS 6.1 and Cordova 2.5 Thanks 回答1: I would advice you

问题 I would like to read the browser's "localstorage" when the browser is off using the OS ! I want to save client data in localstorage and then switch off the browser and the internet and then let an OS program (a windows exe) access and analyse that data and then write new data into that localstorage area so that when the browser restars the new data is in localstorage. This should be possible because my OS (i.e. windows) can read can delete cookies from the browser "files" ... so presumably

I would like to know if i can use local storage for consistent session storage that php can use

问题 I've been trying to use web sql database api in webkit based browsers. I have been using the async api in the main ui thread and a web worker . Both threads access the same database (which as you know is sqlite underthehood) Everything behaves fine but occassionally transactions are lost or one transaction fails and it seems to be a timing/race condition. It appears access to the underlying sqlite database is not thread-safe. A bit more background. My web worker is simply executing a query

问题 My Windows Store (aka Windows 8) application uses the default Grid Application template to show the items. The item template there includes an image with overlaid text information. To diminish the size of application I do not store the images for every item, instead I save an Uri with absolute path (http) to the webserver where the image resides. I modified the standard template to bind to the image Uri (I had to convert the Uri to string for this to work properly) and now whenever I start

问题 I'm trying to save an array consisting of multiple JS objects via localStorage. I guess I'm having the same trouble as Fail when pushing an array of js objects to localStorage and then retrieving it and parsing, but there's no solution to it. var featureArray=[]; map.on('click', function(evt) { if (feature) { featureArray.push(feature.values_); } }); function saveFeatures() { localStorage.setItem('features', featureArray); } saveFeatures(); when I try to load them via localStorage.getItem(

问题 I'm trying to save a value from a url query string that needs to be inserted into forms an any page the user navigates to, but so far I can't get the code to work past the initial landing page that contains the original query string. Using this method to grab the query string value for X, and save it in localStorage for key Xcode: <script> var field = 'x'; var url = window.location.href; if(url.indexOf('?' + field + '=') != -1) { function getUrlVars() { var vars = [], hash; var hashes =
