我有一个从firebase接收数据的角度应用程序,但我不知道如何在视图中显示数据。从firebase检索的数据是一个具有3个具有以下名称的对象的对象:KoAJWEHt6E2krjLgSuB,KoAJWEPc0seRt95JqoH,KoAJWEQDiAsOWwvL2QZ(这些名称是firebase分配的唯一键)。这3个对象保存每个人的分类数据。现在我不知道如何在视图中显示这些数据。我已经尝试过ng-repeat但它没有显示任何内容,并且控制台中没有错误。
控制器:
myApp.controller("classifiedsCtrl",["$scope","$http","$mdSidenav","$mdToast","$mdDialog","$firebaseArray",function($scope,$http,$mdSidenav,$mdToast,$mdDialog,$firebaseArray){
var ref=firebase.database().ref().child('persons');
ref.on('value',function(snapshot){
$scope.classifieds=snapshot.val();
console.log($scope.classifieds);
});
}]);
控制器视图:
<md-card flex="30" ng-repeat="classified in classifieds | filter:classifiedsFilter" class="record">
<md-card-content>
<div class="classified-info" ng-show="!showContact">
<h2 class="md-title">{{classified.title | uppercase}}</h2>
<h3>{{classified.price | currency}}</h3>
<p>{{classified.description}}</p>
</div>
<div class="classified-contact" ng-show="showContact">
<p>
<md-icon class="mdi mdi-account"></md-icon>{{classified.name}}</p>
<p>
<md-icon class="mdi mdi-phone"></md-icon>{{classified.phone}}</p>
</div>
<div layout="row">
<md-button ng-click="showContact=true" ng-show="!showContact">Contact</md-button>
<md-button ng-click="showContact=false" ng-show="showContact">Details</md-button>
<md-button ng-click="showAdmin=true" ng-show="!showAdmin">Admin</md-button>
<md-button ng-click="showAdmin=false" ng-show="showAdmin">Close</md-button>
</div>
<div class="classified-admin" ng-if="showAdmin">
<h3>Admin</h3>
<div layout="row">
<md-button class="md-raised md-primary">Edit</md-button>
<md-button ng-click="deleteClassified($event,classified)" class="md-raised md-warn">Delete</md-button>
</div>
</div>
</md-card-content>
</md-card>

将你的firebase引用传递给firebasearray,如下所示
var ref=firebase.database().ref().child('persons');
$scope.ref=$firebaseArray(ref);
$scope.ref.$loaded().then(function(){
$scope.classifieds=[];
$scope.classifieds=$scope.ref;
})
然后等待ref加载将条件放在html中,如下所示
<div ng-show="classifieds.length>0">
//put your md-card inside this div.
</div>
