问题描述
限时送ChatGPT账号..以下脚本是使用 angularfire、firebase 和 angular 对 firebase 的简单读取.问题是，当我将 AngularFire 从 0.7.1 升级到 .0.8.0 时，脚本完全停止工作，我不确定我做错了什么?
<部分 ng-app="myapp" ng-controller="MyController"><div ng-repeat="数据中的项目"><h3 ng-cloak>{{item.title}}</h3></节><脚本>angular.module("myapp", ["firebase"]).factory("FirebaseService", ["$firebase", function ($firebase) {var furl = "https://helloworldtest.firebaseio/";var ref = new Firebase(furl);返回 $firebase(ref);}]).controller('MyController', ["$scope", "FirebaseService", function ($scope, firebaseservice) {$scope.data = firebaseservice}]);
有了这个配置就可以正常工作了:
<script src='https://cdnjs.cloudflare/ajax/libs/angular.js/1.2.6/angular.min.js'></script><script src='https://cdn.firebase/js/client/1.0.17/firebase.js'></script><script src='https://cdn.firebase/libs/angularfire/0.7.1/angularfire.min.js'></script>但是这样就行不通了:
<script src="https://ajax.googleapis/ajax/libs/angularjs/1.3.0-beta.17/angular.min.js"></script><script src="https://cdn.firebase/js/client/1.0.18/firebase.js"></script><script src="https://cdn.firebase/libs/angularfire/0.8.0/angularfire.min.js"></script>也许最好不要升级.
参见工作 JSFiddle:http://jsfiddle/chrisguzman/z8Lpj63w/看到不工作的 JSFiddle(使用 angularfire 升级):http://jsfiddle/chrisguzman/z8Lpj63w/ 解决方案在你的控制器中:-
$scope.data = firebaseservice.$asArray();//或 .$asObject或者在您的服务中进行:-
return $firebase(ref).$asObject();//或 .$asObject演示
我从未使用过 Firebase，但似乎这是为改进功能而引入的重大更改，在这里找到
<块引用>在以前的版本中，Firebase 数据在 AngularFire 绑定初始化时加载.改进后的 API 提供了两种加载不同格式数据的方法.这些方法是 $asObject() 和 $asArray().
根据来自 Kato
的评论更新这是更改日志，说明了新版本.它说明了许多重大更改的引入，所以我想在 1.0 稳定版本完成之前你可以期待同样的变化.这是官方 API 文档.
The following script is a simple read from firebase using angularfire, firebase, and angular. The issue is that when I upgrade AngularFire from 0.7.1 to .0.8.0 the script completely stops working and I'm not sure what I'm doing wrong?
<body>
<section ng-app="myapp" ng-controller="MyController">
<div ng-repeat="item in data">
<h3 ng-cloak>{{item.title}}</h3>
</div>
</section>
<script>
angular.module("myapp", ["firebase"])
.factory("FirebaseService", ["$firebase", function ($firebase) {
var furl = "https://helloworldtest.firebaseio/";
var ref = new Firebase(furl);
return $firebase(ref);
}])
.controller('MyController', ["$scope", "FirebaseService", function ($scope, firebaseservice) {
$scope.data = firebaseservice
}]);
Wit this configuraiton it works fine:
<script src='https://cdnjs.cloudflare/ajax/libs/angular.js/1.2.6/angular.min.js'></script>
<script src='https://cdn.firebase/js/client/1.0.17/firebase.js'></script>
<script src='https://cdn.firebase/libs/angularfire/0.7.1/angularfire.min.js'></script>
but with this, it doesn't work:
<script src="https://ajax.googleapis/ajax/libs/angularjs/1.3.0-beta.17/angular.min.js"></script>
<script src="https://cdn.firebase/js/client/1.0.18/firebase.js"></script>
<script src="https://cdn.firebase/libs/angularfire/0.8.0/angularfire.min.js"></script>
Perhaps it's better not to upgrade.
See working JSFiddle: http://jsfiddle/chrisguzman/z8Lpj63w/ See not working JSFiddle (with angularfire upgrade): http://jsfiddle/chrisguzman/z8Lpj63w/ 解决方案In your controller do:-
$scope.data = firebaseservice.$asArray(); //or .$asObject
Or do it in your service:-
return $firebase(ref).$asObject(); //or .$asObject
Demo
I have never used Firebase but seems like this is a breaking change introduced to improve the functionality, Found it here
In previous versions, Firebase data loaded when the AngularFire binding initialized. The improved API provides two methods that load data in different formats. Those methods are $asObject() and $asArray().
Update based on comment from Kato
Here is the change log stating the changes in the new version. It states the introduction of many breaking changes, so i guess you can expect the same until 1.0 stable release is done. Here is the official api documentation.
