Angular JS 搜索过滤器未使用 Firebase 过滤数据

Angular JS search filter is not filtering the data by using Firebase

我遇到的问题是搜索过滤器不过滤 table。关于问题可能是什么的任何建议或帮助?我正在制作的应用程序很简单,用户应输入两个文本字符串并将其保存,以便数据可以存储在 firebase 数据库中。然后通过搜索筛选能力。但是,搜索不起作用。

Index.html

 <table class="table table-bordered">
  <thead>
    <th>Plate Number</th>
    <th>Car Brand</th>
  </thead>
  <tbody>
    <tr ng-repeat="customer in customers | filter:search">
      <td>{{customer.CustomerPlateNumber}}</td>
      <td>{{customer.CustomerCarBrand}}</td>
    </tr>
  </tbody>
</table>

script.js(使用 Firebase)

angular.module('myApp', []);

angular.module('myApp').controller('customerCtrl', function($scope) {

  $scope.CustomerPlateNumber = "";
  $scope.CustomerCarBrand = "";
  $scope.customers = {};

  $scope.myData = new Firebase("https://sizzling-torch-2102.firebaseio.com/CustomerInformation");

  // PS, husk at CustomerPlatenumber: må være lik navnet på ng-model. 
  $scope.saveCustomerData = function() {
    $scope.myData.push({CustomerPlateNumber: $scope.CustomerPlateNumber, CustomerCarBrand: $scope.CustomerCarBrand});

  // Empty input after storing data
  $scope.CustomerPlateNumber = "";
  $scope.CustomerCarBrand = "";

  };

  // Two parameters, needs to know what its going to be fired upon, and a function that tells what to do when it is fired. 
  $scope.myData.on('value', function(snapshot) {
    $scope.customers = snapshot.val();
    //not recommended, look at "refresh bindings angular"
    $scope.$apply(); 
  });

});

问题是$scope.customers不是一个数组[]而是一个复杂的JavaScript对象{}。

如果您将其更改为:

$scope.customers=[];

并将 Firebase returning 的复杂散列 table 转换为一个数组,它有效(为了解释,我首先检查 Firebase 是否有方法 return 一个数组而不是使用这个特殊的解释代码):

$scope.myData.on('value', function(snapshot) {
var values = snapshot.val();
for(var myVal in values)
{
  var item = values[myVal];

  $scope.customers.push(item);
}
});
