Question

在自定义过滤器中我有很多function get_detail_transaction($id){ $query = mysql_query("SELECT a.*, b.*, c.*, d.unit_name AS unit_konversi_name, b.transaction_detail_unit, j.unit_name AS unit_utama_name, e.*, f.item_type_name, g.* FROM transactions a JOIN transaction_details b ON b.transaction_id = a.transaction_id JOIN items c ON c.item_id = b.item_id LEFT JOIN units d ON d.unit_id = b.transaction_detail_unit LEFT JOIN item_harga e ON e.item_id = b.item_id LEFT JOIN items_types f ON f.item_type_id = c.item_type LEFT JOIN item_details g ON g.item_id = b.item_id LEFT JOIN members h ON h.member_id = a.member_id LEFT JOIN units j ON j.unit_id = c.unit_id WHERE a.transaction_id = '$id' GROUP BY b.item_id"); return $query; }条件，如果我有选择的话，我想避免重复我的代码。

我尝试创建一个功能，但似乎不想工作。是否可以在过滤器内创建一个功能？如果没有，我如何从过滤器调用函数（如果可能）？

我试图像这样声明：

"if但由于$ scope而收到错误消息。
$scope.mySearch = function(mySearch, searchArr, filled)，但我怎么称呼它？
function(mySearch, searchArr, filled)，收到有关标签mySearch的警告信息。

mySearch : function(mySearch, searchArr, filled)

// I TRIED TO INJECT $SCOPE, BUT THE WAY I DID IT WASN'T PROBABLY GOOD : 

.filter('searchFilter', function($filter, $scope)

    .filter('searchFilter', function($filter)
    {
        return function(items, mySearch, searchArr)
        {

            if((mySearch === "") && (searchArr.name !== ''))
            {         
                var firstSearch = $filter('filter')(items, searchArr.name);
                var city = $scope.myTestFunc(mySearch.result, searchArr, firstSearch);
                return city;
            }


    // THE FUNCTION I WOULD LIKE TO CALL ABOVE

           $scope.myTestFunc = function(mySearch, searchArr, firstSearch)
           {
               // Do the job
           }

       };
});

Answer 1

var my_search = function(mySearch, searchArr, filled){};
//or
function my_search(mySearch, searchArr, filled){}

我更喜欢第一个...将匿名函数存储到变量中。

是否可以在AngularJS中的过滤器内编写函数？
