對新手問題感到抱歉。我想按名稱添加過濾和排序到我的頁面。當我嘗試使用此代碼時,我正在使用控制範圍,但我在使用services.js工廠之後,從變量的產品清單它仍然可以工作,在兩個問題:離子服務工廠中的過濾和分類
- 當我鍵入搜索單詞在搜索框中,過濾器是工作,只顯示過濾項目,但我無法再次清除過濾器(當我刪除搜索詞退格時,該項目仍然被過濾)
- 訂單不再工作了用於排序的項目
下面是代碼: (HTML)
<ion-view view-title="Foods">
<ion-content class="padding">
<div class="bar bar-header item-input-inset">

(Controller.js):
.controller('FoodsCtrl', function($scope,Foods,$filter) {
$scope.foods = Foods.all();
$scope.remove = function(food) {
Foods.remove(food);
};
$scope.foodSearch = {search: ''};
$scope.filterFood = function (item){
return item.title.toLowerCase().indexOf($scope.foodSearch.search.toLowerCase()) >= 0
|| item.name.toLowerCase().indexOf($scope.foodSearch.search.toLowerCase()) >= 0;
}
$scope.isOrderOptionsHide = true;
$scope.reverse=true;
$scope.showOrderOptions = function(){
$scope.isOrderOptionsHide = !$scope.isOrderOptionsHide;
}
var orderBy = $filter('orderBy');
$scope.order = function(predicate, reverse) {
$scope.foods = orderBy($scope.foods, predicate, reverse);
$scope.isOrderOptionsHide = true;
};
})
什麼是'filterFood' in''食物中的食物=(食物|過濾器:filterFood)「',它在哪裏聲明? –
