Angular's cookie read/write method, angularcookie read/write

AngularJS encapsulates a separate module for cookie operations, the module name is ngCookies, if you want to use the need to first introduce angular-cookies.js in the page:

<script src="js/angular.min.js"></script><script src="js/angular-cookies.js"></script>

Then inject the ngCookies module into the dependent modules of our custom modules:

var app = angular.module("myApp",['ngCookies']);

The ngCookies module provides two services related to the reading and writing of cookies: $ cookies and $ cookieStroe. Regardless of the type used, you must first inject it into the controller. To compare the differences between the two, inject it into the controller:

app.controller('namesCtrl', ['$cookies','$cookieStore',function($cookies, $cookieStore){}]);

Set the cookie using the put () method:

$cookies.put(key, value[, options]);

$cookieStore.put(key, value);

For example, set a cookie named "userName" with the value "yangmin ":

// Use $ cookies to set cookies $ cookies. put ('username', 'yangmin ');

// Use $ cookieStore to set cookie $ cookieStore. put ('username', 'yangmin ');

Use the get () method to obtain the cookie:

$cookies.get(key);

$cookieStore.get(key);

For example, obtain the "userName" set above ":

$cookies.get(userName);//yangmin

$cookieStore.get("userName"); //yangmin

Use remove () to delete a cookie ():

$cookies.remove(key[, options]);

$cookieStore.remove(key);

For example, deleting "userName"

$cookies.remove("userName");

$cookieStore.remove("userName");

Difference between $ cookies and $ cookieStore:

1. the cookie value set by $ cookies is generally a string, and $ cookieStroe can be used to set strings, objects, arrays, and so on.

$cookies.put("person",{name:"Amy",age:23});var person = $cookies.get("person");console.log(person.age);//undefined

$cookieStore.put("person",{name:"Amy",age:23});var person = $cookieStore.get("person");console.log(person.age);//23

2. $ cookies can be set as parameters. For example, you can set the cookie expiration time. $ CookieStore cannot set parameters

Var expireDate = new Date (); expireDate. setDate (expireDate. getDate () + 1); $ cookies. put ("userName", "yangmin", {'expires': expireDate}); // "userName" expires one day later
