Question

我需要过滤器1接收一个整数数组。

<select class="form-control"
                            ng-model="vm.data.form.idService"
                            ng-options="service.idService as
                            service.title for service in vm.data.services 
                            |  filter: {active: 'true'} 
                            |  inArray:vm.data.form.servicesIds:'idService'"></select>

我的自定义过滤器是：

angular.module('mainApp').filter('inArray', function($filter){
    return function(list, arrayFilter, element){
        if(arrayFilter){
            return $filter("filter")(list, function (listItem) {
                for (var i = 0; i < arrayFilter.length; i++) {
                    debugger;
                    if (arrayFilter[i][element] == listItem[element]){
                        return true;
                    }else{
                        return false;
                    }
                }
                return true;
            });
        }
    };

var vm.data.form.servicesIds结果为：{{11,12}}，但无效。

此过滤器的目的是接收数组和过滤器，如T-SQL：

SELECT * FROM SERVICES WHERE IdService in (11,12)

这是错误的：

提前谢谢

Answer 1

为什么要在这里注入$ filter

angular.module('mainApp').filter('inArray', function($filter){

不需要。就像保持它一样

angular.module('mainApp').filter('inArray', function(){

Answer 2

我认为您在过滤器的最后一行中缺少一个括号

});

Answer 3

我正在将一个对象与一个简单的数组进行比较。

解决了分号

angular.module('mainApp').filter('inArray', function($filter){
    return function(list, arrayFilter, element){
        if(arrayFilter){
            return $filter("filter")(list, function(listItem){
                for (var i = 0; i < arrayFilter.length; i++) {
                    debugger;
                    if (arrayFilter[i] == listItem[element])
                        return true;
                }
                return false;
            });
        }
    };
});

非常感谢
