Question

我尝试使用简单的数组列表过滤数组，但我似乎无法弄清楚如何使用自定义过滤器，但我无法使其正常工作。编辑：我添加了更多代码。文本框搜索工作正常，但是当我在ng-repeat上添加myFilterby时，它不再过滤。我只是想过滤掉一个数组列表。

<div class="input-group">
    <input type="text" class="form-control" placeholder="Search .." ng-model="searchText">
    <span class="input-group-btn">
      <button class="btn btn-default" type="button">
        <span class="glyphicon glyphicon-search"></span>
      </button>
    </span>
</div>
</div>

<td ng-repeat="a in product| filter:searchText | filter:myFilterBy">
    <img class="avatar" src="img/{{a.image}}" alt="">
    <div class="middleT">
        <p>{{a.brand}} {{a.model}} </p>
        <p>${{a.price}} </p>
    </div>

角：

var HandleModule = angular.module("HandleModule",['rzModule','ui.bootstrap','angular.filter']);
HandleModule.controller('HandleCtrl',function($scope,$http){
    // get data from the server in JSON format
   $scope.chk0 = ['apple', 'orange', 'banana'];
    $http.get('./loader.php').then(successCallback, errorCallback);
    function successCallback(response){
    //success code
    $scope.product = response.data;
    }
    function errorCallback(error){
    //error code
    $scope.product="error";
    }


$scope.myFilterBy = function(e) {
    return $scope.chk0.indexOf(e) !== -1;
}

PHP：

 <?php
$con = mysqli_connect("localhost","root","","product");
$query = "SELECT id, model, brand, price, description, image,  FROM fruits ORDER BY id";
  $result = mysqli_query($con, $query);
$fruits= array();
while($row = mysqli_fetch_assoc($result))
 {
$fruits[] = $row;
 }
echo json_encode($fruits);


?>

使用NG-repeat分别打印数据。我用ng-repeat在html上显示

  <p ng-repeat="a in products ">
  {{a}}

{"id":"1","model":"test1","brand":"orange","price":"4",
 "description":"orange sweet and sour","image":"orange.jpg"}

{"id":"2","model":"test2","brand":"banana","price":"3",
 "description":"yellow sweet","image":"banana.jpg"}

{"id":"3","model":"test3","brand":"apple","price":"5",
 "description":" red sweet crunchy","image":"apple.jpg"}

从我可以从您的问题和后续评论中解读，您只是尝试通过用户输入的搜索文本和静态数组来过滤您的产品数组。

您的问题是您正在尝试将对象与字符串数组进行比较。要解决您的问题，您应该将对象属性（在本例中为品牌）与字符串数组进行比较。

你可以在下面看到它。为简单起见，我删除了对此问题不重要的任何代码。

var HandleModule = angular.module("HandleModule", []);
HandleModule.controller('HandleCtrl', function($scope) {
  $scope.chk0 = ['apple', 'orange', 'banana'];

  $scope.product = [{
    "id": "1",
    "model": "test1",
    "brand": "orange",
    "price": "4",
    "description": "orange sweet and sour",
    "image": "orange.jpg"
  }, {
    "id": "2",
    "model": "test2",
    "brand": "banana",
    "price": "3",
    "description": "yellow sweet",
    "image": "banana.jpg"
  }, {
    "id": "3",
    "model": "test3",
    "brand": "apple",
    "price": "5",
    "description": "red sweet crunchy",
    "image": "apple.jpg"
  }, {
    "id": "4",
    "model": "test4",
    "brand": "pear",
    "price": "6",
    "description": "red sweet crunchy",
    "image": "pear.jpg"
  }];

  $scope.myFilterBy = function(e) {
    return $scope.chk0.indexOf(e.brand) >= 0;
  };
});

<html ng-app="HandleModule">

<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>

<body ng-controller="HandleCtrl">
  <div class="input-group">
    <input type="text" class="form-control" placeholder="Search .." ng-model="searchText" />
  </div>
  <table>
    <tbody>
      <tr>
        <td ng-repeat="a in product| filter:searchText | filter:myFilterBy">
          <div>
            <p>{{a.brand}} {{a.model}} </p>
            <p>${{a.price}} </p>
          </div>
        </td>
      </tr>
    </tbody>
  </table>
</body>
