如何筛选ng-repeat以显示某个columnfield为空字符串的所有项？当我尝试在字段中不输入任何内容时，它似乎总是给予出完整的列表（这是预期的）。我只想见id为1的人。如何调整inputfield中的某个字符对name列的空字段进行ng repeat过滤。
FiddleJs Example
我的看法：

<div class="panel-heading">
   <h3>Filtered by {{filterValue}}</h3>
   <input ng-change="filter()" ng-model="filterValue"/>
</div>
<div class="panel-body">
   <ul class="list-unstyled">
     <li ng-repeat="p in filteredPeople">
       <h4>{{p.name}} ({{p.age}}) id: {{p.id}}</h4>
     </li>
   </ul>
</div>

字符串
控制器：

var people = [{
        name: '',
        age: 32,
        id: 1
    }, {
        name: 'Jonny',
        age: 34,
        id: 2
    }, {
        name: 'Blake',
        age: 28,
        id: 3
    }, {
        name: 'David',
        age: 35,
        id: 4
    }];
    
    $scope.filter = function (value) {
     $scope.filteredPeople = $filter('filter')(people, {
        name: $scope.filterValue
     });
    }

    $scope.people = people.slice(0);
