我已經嘗試了很多這個問題的答案，但沒有任何工作。
的錯誤：眼下當加總的數據項符合要求的項目，該項目從列表中刪除，但名單沒有刷新與在選擇下拉菜單或子列表中刪除該項目的視圖。
我認爲有一些具體的事情我的代碼，所以我在這裏重建我的功能：
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, filterFilter) {
Array.prototype.sum = function(prop) {
var ptotal = 0
for (var i = 0, _len = this.length; i < _len; i++) {
ptotal += this[i][prop]
}
return ptotal
}
$scope.owners = [{
"id": "1",
"name": "parent 1"
}, {
"id": "2",
"name": "parent 2"
}];
$scope.children = [{
"id": "1",
"total": "2",
"owner": "1",
"name": "child 1"
}, {
"id": "2",
"total": "2",
"owner": "2",
"name": "child 2"
}, {
"id": "3",
"total": "1",
"owner": "2",
"name": "child 3"
}];
var random = Math.floor(Math.random() * $scope.owners.length);
$scope.selectedOwner = $scope.owners[random];
$scope.childrenList = $scope.children.filter(function(x) {
return x.owner == $scope.selectedOwner.id;
});
$scope.remove = function(child) {
}
$scope.ownerChange = function(owner) {
$scope.selectedOwner = owner;
$scope.childrenList = $scope.children.filter(function(x) {
return owner.id == $scope.selectedOwner.id;
});
}
$scope.data = [];
$scope.add = function(child) {
$scope.totalInit = filterFilter($scope.children, {
id: child.id
});
var total = $scope.totalInit.sum("number");
var complete = filterFilter($scope.data, {
id: +child.id
}).length;
var number = +complete + 1;
var input = {
"id": child.id,
"name": child.name,
"number": number
};
if (+number >= +child.total) {
$scope.children = $scope.children.filter(function(x) {
return x.id != child.id;
});
$scope.ownerStatus = filterFilter($scope.data, {
id: child.id
}).length;
if ($scope.ownerStatus === 0) {
$scope.owners = $scope.owners.filter(function(x) {
return x.id != child.owner;
});
}
}
$scope.data.push(input);
};

有什麼問題？當您在下拉列表中進行更改時，列表無法正確顯示？ – Pradeepb
當我進行更改（從數組中刪除項目）時，下拉選項和列表在視圖中不會更新。 – pixeloft
