In mobile Web development, often use to localstorage to cache some data, in general, we need to follow the following code to use it will not be a problem. if (window.localstorage) { Localstorage.setitem (' key ', ' value '); } But just so judged is not enough, now some browsers have a function called no trace browsing , as the name suggests, is the user in the process of browsing the Web page, nothing is cached, nothing record, leaving no traces.

Since the discovery of cookie storage in the development is in the HTTP request header, it greatly affects the data request interaction.So to learn the H5 of several storage optimization methods, hereby note. Storage mode:1. Local storage localstorage Sessionstorage;2. Offline storage application cache;3. Browser database IndexedDB; Study and use judgment:This is a browser-compatible search site: http://caniuse.com/Figure one:

Localstorage local storage methods are as follows:Setitem:function (key, value)Getitem:function (Key)Removeitem:function (Key)Clear:function ()Length:intKey:function (i)Isvirtualobject:trueWhen the value of K is stored locallyLocalstorage.setitem (' K ', ' a '); stored locally, you can call directly json.stringify () convert it to a string Function SetData (k,v) { var a = json.stringify (v); Localstorage.setitem (k,a); } read it out and cal

The cookie size is limited, and every time you request a new page, the cookie is sent in the past, which virtually wastes bandwidth, and the cookie needs to be specified.Domain and cannot be called across domains.WEB Storage has setitem,getitem,removeitem,clear and other methods, the operation is not as simple as a cookie requires the front-end developer to encapsulate Setcookie,getcookie.The role of cookies is to interact with the server as part of the HTTP specification and the Web storage onl

, through degrees Niang found the root cause of the problem---safari non-trace browsing will affect localstorage. So you just have to change this sentence a little bit.try { Sessionstorage.setitem ("Loginphone", Loginphone), } catch (e) { alert ("You are in a no-trace view, unable to jump for You"); }Here is the code before the modification: var Loginphone; function Submitbindinfo () {if (Checksubmitm

1,web Storage Introduction The HTML5 Web Storage feature is to have the Web page save some information on the user's computer. Web Storage is divided into two categories: (1) Local storage, corresponding to the Localstorage object. Used to save data for a long time, and any page in the site can access that data.(2) session storage, corresponding to the Sessionstorage object. Used to temporarily save data for a window (or tab). Before a visitor close

Log in when the login is successful, you need to put the information into a cookie, NPM install several Angular2-cookie ng2-cookies angular2-cookiesAccording to the above method, always error, method is undefined, Baidu Google no fruitFinally, one of the local storage solutions to LOCALSTORAGE,HTML5, easy to use Localstorage.setitem (' User ', Json.stringify (this.users)); This.user = Json.parse (Localstorage.getitem (' user ')); L

Note that the data in the Localstorage is Fu, and the Json.parse conversion is used.Ideas are as follows:1, read the cached data, for example, called Data_cache2 Judge Data_cache,if (!data_cache) {Access interface, get data, string json.stringify to the local name Data_cache, and then recursively return the function name}3 Else parse the data string and then handle it.For example://gets the first-level categorical data and saves it to a localfunctiong

HTML5 has not come to its heyday, but this does not prevent us from gradually using some of the features of HTML5 in actual projects.

The Web Storage in HTML5 includes two ways of storage: Sessionstorage and Localstorage.Sessionstorage is used to store data locally in a session, which can only be accessed by a page in the same session and destroyed when the session ends. So sessionstorage is not a persistent local store, only session-level storage.While Localstorage is used for persistent local storage, the data will never expire unless the data is actively deletedThe Web Storage in

Sometimes, we need to store data in Sessionstorage and Localstorage, and the benefits are: 1 Cached data 2 Reduce memory footprint However, storage can only store string data, but cannot be stored directly for arrays or objects that are commonly used in JS. var obj = {name: ' Jim '}; Sessionstorage.obj = obj; Localstorage.obj = obj; var arr = [1,2,3]; Sessionstorage.obj = arr; Localstorage.obj = arr; The above wording is not successf
