Everything works from the phones browsers just not from the WebView. Activity: public class BrowserActivity extends Activity { @Override public final void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView browser = (WebView) findViewById(R.id.webView); browser.setHapticFeedbackEnabled(true); browser.getSettings().setJavaScriptEnabled(true)

npm test is fine, but it also raises the error uncaught at askBackend ReferenceError: localStorage is not defined

I'm happy to put a button saying "Delete my data", this is under my control, but are there ways beyond my control that localStorage data may be deleted? Or not used (ie. Incognito mode/private browsing mode)? Thanks 回答1: localStorage is editable by the user , it's similar to the cookies . User can delete / edit it if he wants , so you should make ur tests on server sides ... here's an

localStorage is not defined (Angular Universal)

When my client starts, it read a token about user info from localStorage. @Injectable() export class UserService { foo() {} bar() {} loadCurrentUser() { const token = localStorage.getItem('token'); // do other things }; } Everything works well, however I got this in the server side (terminal) because of server rendering: EXCEPTION: ReferenceError: localStorage is not defined I got the idea from ng-conf-2016-universal-patterns that using Dependency Injection to solve this. But that demo is really old.

vue：使用不同参数跳转同一组件，实现动态加载图片和数据，以及利用localStorage和vuex持久化数据

由 本秂侑毒 提交于 2019-12-03 05:21:12
需求：通过不同的参数复用同一组件，实现动态加载数据和图片，同时，在页面刷新时，图片依旧可以加载成功。 过程出现的bug和问题： 　　1、使用params传参后，再次刷新页面，参数丢失导致数据无法再次加载 　　2、改用query进行传参后，页面刷新后图片无法加载，这是由于图片的url是在created钩子函数调用查询数据api后才进行赋值，而赋值之后页面已经渲染完成，导致图片无法加载成功 解决方案： 　　1、通过localStorage将数据持久化，在跳转到当前路由时，先使用localStorage将数据持久化，这里可以配合vuex进行操作 　　2、页面渲染前，图片的url直接读取localStorage的值，就不会出现页面渲染完成，url还没被赋值导致图片无法加载的情况 附上代码： 　　需要从 /zyview 跳转至 /viewmessage 　　/zyview跳转部分： this.$router.push({ // path: `/viewmessage/${this.names[index]}`, // 使用下列方法方法跳转路由，就不会出现点击tab后再次跳转的bug name: "viewmessage", query: { name: this.lists[index].m_name, // 此为药品名称 index: index, // 药材索引 mid: this

关于localStorage储存多个数据

由 有些话、适合烂在心里 提交于 2019-12-03 04:29:16
localStorage： 是一种你不主动清除它，它会一直将存储数据存储在客户端的存储方式，即使关闭了客户端（浏览器)，属于本地持久层储存 sessionStorage： 用于本地存储一个会话（session）中的数据，一旦会话关闭，那么数据会消失，比如刷新。 localStorage只能存字符串 ，如果需要存对象，首先要转化为字符串 利用JSON.stringify() ( 存单个就不用考虑这些了 ) setItem 存 let rowVal = { bCode: row.gymnasium.code, bName: row.gymnasium.name, bAddress: row.gymnasium.address, bCoachName: row.coach.name, bCozchNickName: row.coach.nickname, bIphone: row.coach.phoneNumber }; localStorage.setItem("rowVal", JSON.stringify(rowVal)); 然后取出rowVal对象用JSON.parse() 再把字符串转为对象( 然后用哪个 "." 哪个就行了 ) getItem 取 computed: { rowVal() { const rowVal = JSON.parse(localStorage

Does HTML5 localStorage maximum size include key names?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: HTML5's localStorage WebStorage has a maximum size of 5MB. Does this include the key names? For instance, if I were to use key names "quite-a-long-key-name-and-this-is-only-1" instead of "key1", would I run out of space sooner? On a slightly related topic; is there any de-facto convention for naming localStorage keys? How are namespace collisions prevented when using third party JS scripts? 回答1: Does this include the key names? Yes those do, they become part of data eg they identify data you store and later retrieve so that got to be saved

Does iOS 5.1 clear the localStorage when I close a PhoneGap app in the multitasking bar?

But Kerri Shotts wrote a code to support NATIVE persistence of localStorage with phoneGap : http://pastebin.com/5881768B (it will copy the localstorage file to a secure folder and restore it if necessary) And phonegap team is working on that : https://issues.apache.org/jira/browse/CB-330 回答2: It's a widely published misconception that closing apps on the 'multitasking bar' actually closes the application. It does no such thing - the
