AngularJS入门教程之Cookies读写操作示例

虽然使用JavaScript创建和获取Cookie很简单,AngularJS还是把它作为一个单独的模块进行了封装,模块名为ngCookies,和前面的教程中做法一样,先引入angular-cookies.js:

<script type="text/javascript" src="https://www.jb51.net/angular-1.3.0.14/angular-cookies.js"></script>

然后將ngCookies模块注入到我们自定义的模块中:

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

这里我们需要把Cookies读写相关的服务$cookieStore注入到控制器中。通过$cookieStore的get和put方法进行读和写操作

我们看一个完整的案例:

<!DOCTYPE html> <html ng-app="cookiesMod"> <head lang="en"> <meta charset="UTF-8"> <script type="text/javascript" src="https://www.jb51.net/angular-1.3.0.14/angular.js"></script> <script type="text/javascript" src="https://www.jb51.net/angular-1.3.0.14/angular-cookies.js"></script> <title>tutorial08</title> </head> <body ng-controller="CookiesController" ng-init="init()"> <button ng-click="getInfo()">获取Cookies信息</button> </body> <script> var cookiesMod = angular.module("cookiesMod",['ngCookies']); cookiesMod.controller("CookiesController",function($scope,$log,$cookieStore){ $scope.init = function() { $log.info("init functionn"); $cookieStore.put("person",{name:"Rongbo_J",age:23}); } $scope.getInfo = function() { var person = $cookieStore.get("person") ; alert("name : " + person.name +" , "+ "age : " + person.age); } }); </script> </html>

在页面加载时我们写入Cookies信息,cookie名为person,值为{name:"Rongbo_J",age:23},点击按钮获取cookie信息并以对话框的形式弹出。

接下来看一下效果:
