local-storage

问题 Can i use a Local Storage object to store another Local Storage object ? Thank u in advance 回答1: You can store any object in Web Storage, as long as you can stringify it. But you have only one instance of localStorage in your browser, so you don't have to ask if you can do that, because you can't create new instances. 来源： https://stackoverflow.com/questions/10269334/data-supported-by-html5-local-storage

问题 I am using Ionic 2 storage for storing user credentials. On uninstalling the App, storage is not clearing so after re-installing, the App is picking up the user credential of the previous user. This issue is occurring only in signed APKs. Tested on samsung on7 and lenova vibe models. How to clear the storage on uninstall? what I am doing wrong? 回答1: Set android:allowBackup to false in AndroidManifest to XML 回答2: you should not need to do anything for this to happen. This looks like a bug in

问题 I don't think it matters for the purpose of this question what my exact setup is, but I just noticed this in my React and React Native apps, and suddenly realized they are not actually checking any kind of validity of the JWT that is stored. Here is the code: const tokenOnLoad = localStorage.getItem('token') if (tokenOnLoad) store.dispatch({ type: AUTH_USER }) It's probably not really an issue, because the token is attached to the headers and the server will ignore any request without a valid

问题 Well, I'm starting with nuxt and I have following routes: /home /dashboard /login I want to protect the /dashboard, but only for users logged in with a token in localStorage . The simplest way I thought of doing this was by creating a /middleware/auth.js export default function () { if (!window.localStorage.getItem('token')) { window.location = '/login' } } and registering it in the /dashboard/index.vue component. <script> export default { middleware: 'auth', } </script> But I cannot access

问题 I was just reading the jQuery .data() API reference. Beforehand, I speculated that it might work by assigning 'data-*' attributes to page elements; effectively a shortcut to $('#foo').attr('data-foobar', 'bar') . (1) Imagine it did work like this, though it seems it doesn't, and you switched from one jQuery Mobile page to another and then back again, would the 'data-*' attributes still be attached to the elements, or does jQM effectively reload from the downloaded HTML? In the reference,

问题 How do I use LocalStorage with MSAL.js? According to this, there's a property, cacheLocation, I need to set to 'localStorage'. The following is still using sessionStorage: var clientApplication = new Msal.UserAgentApplication(applicationConfig.clientID, applicationConfig.authority, function (errorDesc, token, error, tokenType) { // Called after loginRedirect or acquireTokenPopup }); clientApplication.cacheLocation = 'localStorage'; 回答1: Looks like the documentation is slightly out of date,

问题 I'm not sure why, as i've done this before and it worked fine, and i'm thinking it might be because of a browser issue/bug: localStorage.setItem('foo', 'bar') alert(localStorage.getItem('foo')); I'm in Firefox 3.6.6 and it alerts "bar" but if I do: //localStorage.setItem('foo', 'bar') alert(localStorage.getItem('foo')); I get NULL. It should return bar still as it's in my storage. Also, this is just a web page that it's running on. 回答1: Are you running the script locally via file: ? If so,

问题 How can I count how many different values I have in 1 localstorage key. For example: This is my localstorage: [{"id":"item-1","icon":"google.com"},{"id":"item-2","icon":"youtube.com"}] For this example I'd like an alert of 2 different values. So basically I want to count the {} .. Is that possible? 回答1: localStorage is an object, so just localStorage.length gives you the number of entries. However I think I might be misunderstanding you. Do you mean you have one key, and that key's value is a

问题 I want to just store the image or pdf or any type of file in local storage. So, is there a way to store a file in LocalStorage? 回答1: Here is a standalone service which works on Angular 6/7/8. It downloads, stores and retrieves a file in local storage. import { Injectable } from '@angular/core'; import { Observable } from 'rxjs'; import { HttpClient } from '@angular/common/http'; import { map, flatMap } from 'rxjs/operators'; @Injectable({ providedIn: 'root' }) export class

问题 I want to make an app which gets my coördinates and shows them in google maps (using phonegap and testing on emulator 2.2). Then stores those coördinates in localstorage. I have never used localstorage before so i am not sure on how to do this. I got the geolocation part working. If anyone could adjust my code or show a tutorial which explains how to save the lat/long that i will retreive as i don't have a lot of experience using web-langauges. It would be greatly appreciated. <!DOCTYPE HTML
