JavaScript-错误：[filter：notarray]预期的数组,但收到的是：0

错误

Error: [filter:notarray] Expected array but received: 0

html

getConcessionaireList函数的激活器(菜单项).

<ion-item ng-click="getConcessionaireList()" >
</ion-item>

输入搜索$scope.concessionairesList中显示的数据的列表

<input type="search" placeholder="Search" ng-model="searchQuery">
<ion-list>

单击Activator时,此处将显示$scope.concessioniresList中的值.

<ion-item class="item item-icon-left" ng-repeat="x in concessionairesList track by $index | filter:searchQuery" href="#/app/encodereading/{{x.accountNumber}}">
    {{x.accountNumber}} - {{x.meterNumber}} - {{x.lastName | capitalize}}, {{x.firstName | capitalize}} {{x.middleName | initial}}
</ion-item>

js

将使用php从数据库中获取数据

$scope.getConcessionaireList = function(){
      $http.get('http://localhost/test/php/getConcessionaires.php').then(function(res){
        $scope.show($ionicLoading);
        console.log(res.data);
        $scope.concessionairesList = res.data;
      }).finally(function(){
        $timeout(function(){
          $scope.hide($ionicLoading);
        }, 1000)
      })
    }

解决方法:

在应用过滤器之前,您正在使用$index跟踪.要解决此问题,请将您的表达式更改为：

<ion-item class="item item-icon-left" ng-repeat="x in concessionairesList  | filter:searchQuery track by $index" href="#/app/encodereading/{{x.accountNumber}}">
