若如初见. 提交于 2020-03-18 12:27:11
问题 I'm Actually using Ionic Storage. and I heard About The Ionic Native Storage I Don't Know the Exact Difference Between Them. Which One Is Preferred to use? Which is the Best Choice? Thank You!, 回答1: They have basically the same purpose and both work with key/value to store items, but i think Ionic Storage is better and i'll tell why.

Speed/cost of localStorage

问题 How fast is looking up a value in localStorage with Javascript? Does anyone have links to any performance tests that indicate whether or not it is worth caching the data in a JavaScript object? Or does the browser already cache values that are accessed from localStorage anyway? I am particularly interested in Firefox and Chrome implementations of localStorage. 回答1: For what it's worth, here is a jsperf test. The benchmark usage of localStorage is significantly slower than access of a regular

萝らか妹 提交于 2020-03-06 02:40:30
问题 I have a little question. Does localStorage get wiped off once the user clears the bowser history? If yes, then is there a way that I can save a URL as a string on the mobile device somewhere which always stays there even if the user or any other application forces the browser history to be cleared. And I can go get that string(URL) whenever I need it for my mobile app. The thing is I want to save URL of a restful service which fetches updates to the mobile client. I want that whenever a user

Syncing localStorage

六月ゝ 毕业季﹏ 提交于 2020-03-01 04:17:46
问题 I'm looking for a solution that allows a browser's localStorage to be less local, so that people can access their data on multiple devices. The traditional way is to run a database on a server and have people log in; but I'm trying to avoid doing that. I'd like the server side to be lightweight - perhaps even completely static if possible - and to not have the job of safely storing passwords, worrying about data protection etc. Many browsers have a login of some sort -- Google Account,

How can i use localStorage to maintain state after a page refresh in React

三世轮回 提交于 2020-02-05 05:17:48
问题 Each time a user logs in, i want the state to remain at 'true' even if there is a page reload. The state is set initially to false, (let _authed = false). But when i reload the page, it goes back to false, which is the index page. What i did When the user logs in, i save the user's details in localStorage and when the user logs out, i cleared the localStorage and i set it to false. (this works fine) In the setAuthed() function, i tried to check if the user i stored in localStorage is not null
