现在我有一个表,当前显示所有条目形成firebase中的“事件”节点。
但是,我只想显示登录用户创建的事件。现在他们正在显示所有用户创建的事件。
我猜我可以在标签中的ng-repeat之后使用ng-if指令,但是,我不知道该放入什么内容。
这是我的表:
<table class="table table-striped">
<thead>
<tr>
<th>Title</th><th>Location</th> <th>Actions</th>
</tr>
</thead>
<tbody>
<tr scope="row" ng-repeat="event in events | reverse" >
<td>{{event.title}}</td>
<td>{{event.location}}</td>
<td><button class="btn btn-primary" ng-click="events.$remove(event)"><span class="glyphicon glyphicon-trash" aria-hidden="true"></span></button></td>
</tr>
</tbody>
用户对象如下所示:
{
"provider": "password",
"uid": "635gt3t5-56fe-400d-b50b-1a6736f8874a",
"token":
"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6Im1pY2hhZWwubGFyaXZpZXJlMTk3M0BnbWFpbC5jb20iLCJlbWFpbF92ZXJpZmllZCI6ZmFsc2UsImlhdCI6MTQ2OTEyNTYyOSwidiI6MCwiZCI6eyJwcm92aWRlciI6InBhc3N3b3JkIiwidWlkIjoiNmY5ZmM0NTUtNTZmZS00MDBkLWI1MGItMWE2NzM2Zjg4NzRhIn19.yIzzV7Or7tUlXi-sSWeioNx6LLoQ0U9qnW1X06rpSmA",
"password": {

"isTemporaryPassword": false,
"profileImageURL": "https://secure.gravatar.com/avatar/5f9effbf8cbea69792c595079cf25d38?d=retro"
},
"auth": {
"provider": "password",
"uid": "635gt3t5-56fe-400d-b50b-1a6736f8874a",
"token": {
"email_verified": false,
"email": "xxxxxx.xxxxxx1234@gmail.com",
"exp": 1469212029,
"iat": 1469125629,
"sub": "635gt3t5-56fe-400d-b50b-1a6736f8874a",
"auth_time": 1469125629,
"firebase": {
"identities": {
"email": [

]
}
}
}
},
"expires": 1469212029
}
我的控制器看起来像这样:
angular.module('myApp').controller('ChatCtrl', function($scope, user,
Ref, $firebaseArray, $timeout) {
console.dir('user: ' + JSON.stringify(user));
// synchronize a read-only, synchronized array of events, limit to most recent 10
$scope.events = $firebaseArray(Ref.child('events').limitToLast(10));
// display any errors
$scope.events.$loaded().catch(alert);
// provide a method for adding a event
$scope.addEvent = function(newEvent) {
if (newEvent) {
// push a event to the end of the array
$scope.events.$add({
title: newEvent.title,
location: newEvent.location,
createdBy: user.uid,
createdAt: Firebase.ServerValue.TIMESTAMP
})
// display any errors
.catch(alert);
}
};
function alert(msg) {
$scope.err = msg;
$timeout(function() {
$scope.err = null;
}, 5000);
}
});
这就是firebase中用户和事件的样子:

要获得您正在寻找的结果,请尝试使用angularjs过滤器。
在你的控制器中添加一个名为
的函数<tr scope="row" ng-repeat="event in events | reverse" >
此功能将作为一个过滤器,通过将事件的创建对象与用户的uid进行比较,只允许通过当前用户创建的事件。
然后在你的html中更改这一行
<tr scope="row" ng-repeat="event in events | reverse | filter:filterByUID" >
要
merge
这告诉angularjs您希望使用我们在控制器中定义的过滤器过滤您的项目。
修改:以下是使用自定义过滤器的参考:AngularJS : Custom filters and ng-repeat
