Question

我遇到的问题是搜索过滤器不会过滤表格。对问题的任何建议或帮助？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保存，以便将数据存储在firebase数据库中。然后通过搜索过滤能量。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不是数组[]，而是复杂的JavaScript对象{}。

如果您将其更改为：

$scope.customers=[];

并且将Firebase返回的复杂哈希表转换为数组，它可以工作（为了便于解释，我首先检查Firebase是否有返回数组的方法而不是使用这个特定的解释代码）：

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

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

Angular JS搜索过滤器不使用Firebase过滤数据
