具有自定义过滤功能的AngularJS多重过滤器

javascript

我正在尝试使用多个过滤器+自定义过滤器功能过滤列表。

我想添加一个自定义过滤器,以使其 年龄 基于两个输入值 min_agemax_age (在年龄之间)进行过滤。

在研究文档之后。我发现有人有类似的问题,用户MarkRajcok回答了看起来不错,应该可以工作。但是我在将其应用于我的代码时遇到了问题,这主要是因为我还有其他多个过滤器。

视图

<div ng-app ng-controller="MainController">
<table class="fancyTable">
    <tr>
        <th>Player id</th>
        <th>Player name</th>
        <th>Age</th>
    </tr>
    <tr>
        <td><input ng-model="player_id" /></td>
        <td><input ng-model="player_name" /></td>
        <td>
            Min Age:<input ng-model="min_age" />
            Max Age:<input ng-model="max_age" />
        </td>
    </tr>
    <tr ng-repeat="player in players | filter:{id: player_id, name:player_name, age:ageFilter}">
        <td>{{player.id}}</td>
        <td>{{player.name}}</td>
        <td>{{player.age}}</td>
    </tr>
</table>

控制者

function MainController($scope) {

$scope.player_id = "";
$scope.player_name = "";
$scope.player_age = "";
$scope.min_age = 0;
$scope.max_age = 999999999;

$scope.ageFilter = function(player) {
    return ( player > $scope.min_age && player.age < $scope.max_age);
}

$scope.players = [
        {"name": "Rod Laver",
            "id": "rod",
            "date": "1938/8/9",
            "imageUrl": "img/rod-laver.gif",
            "age": 75},
        {"name": "Boris Becker",

尝试这个:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}
