我正在使用 AngularJS,并且我已经加入了子文档(来自下面的 JSON 的“orderfood”)并获取了我的 JSON 数据的数量总和,在 orderfood
下我有 confirm
属性。我只想过滤 confirm
属性中具有值 placed
的数据。我的plunker demo
我得到的结果
3 quantities of V 4 Vanilla should be prepared
3 quantities of Power cut should be prepared
预期结果
2 quantities of V 4 Vanilla should be prepared
3 quantities of Power cut should be prepared
JSON
[{
"_id": "56e3bff0e9932ca6425e6f65",
"orderfood": [
{
"qty": "2",
"confirm": "placed",
"name": "V 4 Vanilla"
}
],
"name": "Rohit",
"created": "2016-03-12T07:06:24.424Z"
},
{

"__v": 10,
"orderfood": [
{
"qty": "1",
"confirm": "cancelled",

"name": "Power cut"
}
],
"name": "Rohit",
"created": "2016-03-12T06:55:23.244Z"
}];
Controller
$scope.getOrderFoods = function() {
var orderfood = [];
$scope.reduce= function(data){
return data.reduce(function(previousValue,
currentValue, currentIndex, array) {
return previousValue + parseInt(currentValue.qty);
}, 0);
}
angular.forEach($scope.orders, function(order) {
angular.forEach(order.orderfood, function(orderfoo) {
if (orderfood.indexOf(orderfoo) == -1) {
orderfood.push(orderfoo);
}
})
});
return orderfood;
}
HTML
<div ng-repeat="(key,data) in getOrderFoods() | groupBy:'name'">
<p><span>{{reduce(data)}}</span> quantities of <span>{{key}}</span> should be prepared </p>
</div>
最佳答案
只需将条件添加为 ng-repeat
中的过滤器即可:
<div ng-repeat="(key,data) in getOrderFoods() | filter: {confirm: 'placed'} | groupBy:'name'">
