在AngularJS中管理本地存储,您可以使用内置的$window.localStorage
对象
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
localStorageService
的服务,该服务将封装对$window.localStorage
的操作:var app = angular.module('myApp', []);
app.service('localStorageService', function($window) {
this.setItem = function(key, value) {
$window.localStorage[key] = value;
};
this.getItem = function(key) {
return $window.localStorage[key];
};
this.removeItem = function(key) {
delete $window.localStorage[key];
};
this.clear = function() {
$window.localStorage.clear();
};
});
localStorageService
服务,并使用它来存储、检索、删除和清除本地存储数据:app.controller('myController', function($scope, localStorageService) {
// 设置本地存储项
localStorageService.setItem('username', 'JohnDoe');
// 获取本地存储项
$scope.getUsername = function() {
return localStorageService.getItem('username');
};
// 删除本地存储项
$scope.removeUsername = function() {
localStorageService.removeItem('username');
};
// 清除本地存储
$scope.clearLocalStorage = function() {
localStorageService.clear();
};
});
ng-click
指令调用函数以执行本地存储操作:<!DOCTYPE html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>AngularJS LocalStorage Example</title>
</head>
<body ng-controller="myController">
<h1>AngularJS LocalStorage Example</h1>
<p>Username: {{getUsername()}}</p>
<button ng-click="removeUsername()">Remove Username</button>
<button ng-click="clearLocalStorage()">Clear Local Storage</button>
</body>
</html>
现在,您已经在AngularJS应用程序中成功管理了本地存储。使用localStorageService
服务,您可以轻松地在应用程序中存储、检索、删除和清除数据。
