local-storage

问题 What is the difference between ngStorage and $window.localStorage? When is it better to use one instead that the other? I have to choose one of them for a web app. I have to save data of profile user and the token 回答1: This is normal html5 local storage: With local storage, web applications can store data locally within the user's browser. Before HTML5, application data had to be stored in cookies, included in every server request. Local storage is more secure, and large amounts of data can

问题 I have a web application that store information about recently visited pages, let's call them A. When a user visits another page type, called B, I render a menu at the top with a button to point to the most recently visited A-page. The B-pages are accessible either through an A page or a B page and can by the user be considered a property of A. This works fine but it becomes a problem when someone opens two tabs and when being on a B-page in tab 1 with a link to the A-page A1 they open a new

问题 I'm trying to build a custom Angular 2 http request by extending the default and I'm using Ionic 2 local storage to store the auth token. (Will likely use file system in future). My issue is how to return a resolved promise from my http service so I can subscribe to the Observable within my component. I've tried Observable.fromPromise and other variations to no avail. request(url: string|Request, options?: RequestOptionsArgs): Observable<Response> { // Get the token used for this request. //

问题 I'm looking for a way to get all the information out of localStorage. The trouble I'm having is I don't know what the data will be as it is user generated. So here what happens, a user inputs some text, it uses javascript to manipulate it depending on what check boxes they have ticked on the input form. these boxes are for symbols for example if they tick the box for @ then the text + the @At (symbol then word) will be placed in local storage with the other half of the pair as a Boolean (1 or

问题 I have a rest api for generating token, which i'm using in angular 4 client side, but the question is where to store this token. In the internet i found that i can store in local storage or in the cookie. So my question is, if store token is the local storage for example, and i have just copied the valid token from another browser, then i will have a valid token, so there is any security of storing token like that, and basically the same with cookies, or maybe i missed some important

问题 I'm working on a web application, which acts pretty much like a native application for both iOS and Android. However the Javascript files (jQuery + my own) and the css file together are pretty large for mobile use, which make the app slow to load if the user doesn't have 3G enabled. I therefore started to think about storing these files offline. However aside from the cache.manifest (which in my knowledge only kicks in when there is no internet connection to enable offline use) I have found

问题 I would like to use HTML5 Local Storage with my Ember.js. I haven't been able to find any examples of doing this without Ember Data. How should this be done? What do I need to consider? 回答1: So let's say we have an object called Storage that in our real-world implementation would represent an adapter-like object for the localStorage to store and retrieve data: App.Storage = Ember.Object.extend({ init: function() { this.clearStorage(); var items = ['foo', 'bar', 'baz']; localStorage.items =

问题 I've made a Chrome extension with an options page. The data is saved in localstorage and works just fine. Chrome doesn't sync the localstorage to the cloud, just the extensions. This means that any user data will not sync to other computers of the same google account. I can not find an API at http://developer.chrome.com/extensions/docs.html which allows me to sync the user-chosen preferences. What methods do you suggest? 回答1: In the (hopefully near) future, you'll be You are now able to store

问题 I am setting some values at the option page. This is now working okay. But i am unable to access the data setted in the background.html or in the content script. I have read that something like this is possible with messaging but for me is the documentation a little bit hard to understand. If someone could point me out in the right direction it would be good. Example story> I am setting this value at the options page localStorage.setItem("somedata" , "true"); Then if i would access the same

问题 Trying to simply store a variable using localStorage, retrieve it later on as an integer, add it to another integer and then store it again. However, it seems to be treating the integer as a string and concatenates numbers instead. I have tried using JSON.stringify and parse but it doesn't work and I can't see why. (the variable hours is definitely an integer.) if (localStorage.getItem('hours_worked') === null) { localStorage.setItem('hours_worked', JSON.stringify(hours)); } else { var temp
