【问题描述】:
我正在创建一个单页应用程序,用户在其中搜索一个术语,结果保存在一个变量中,然后路由一个显示结果的新页面。我有这个功能,但是我希望在用户返回上一页时清除变量,最重要的是当用户注销时。这样做的正确方法是什么?我希望工厂为我想要的某些页面保存内容,并为某些我不想要的页面清除它们,例如“home”或“logout”。
工厂:
angular.module('firstApp')
.factory('fact', function () {
var service = {};
var _information = 'Default Info';
service.setInformation = function(info){
_information = info;
}
service.getInformation = function(){
return _information;
}
return service;
});
控制器:
angular.module('firstApp')
.controller('InformationCtrl', function($scope, $http, $location, fact) {
$scope.message = 'Hello';
$scope.result = fact.getInformation();
$scope.sub = function(form) {
console.log($scope.name);
$scope.submitted = true;
$http.get('/wiki', {
params: {
name: $scope.name,
}
}).success(function(result) {
console.log("success!");
$scope.result = result;
fact.setInformation(result);
$location.path('/informationdisplay');
});;
}
});
路线
angular.module('firstApp')
.config(function ($routeProvider) {
$routeProvider
.when('/information', {
templateUrl: 'app/information/input.html',
controller: 'InformationCtrl',
authenticate : true
})
.when('/informationdisplay', {
templateUrl: 'app/information/results.html',
controller: 'InformationCtrl',
authenticate : true
});
});
input.html
<div class="row">
<div class="col-md-6 col-md-offset-3 text-center">
<p>{{result}}</p>
<form class="form" name="form" ng-submit="sub(form)" novalidate>
<input type="text" name="name" placeholder="Name" class="form-control" ng-model="name">
</br>
<button class="btn btn-success" type="submit" class="btn btn-info">Check</button>
</div>
</div>
结果.html
<div ng-include="'components/navbar/navbar.html'"></div>
<div class="row">
<div class="col-sm-4 col-sm-offset-4">
<h2>Information Results</h2>
<p>{{result}}</p>
</div>
</div>
</div>
