Question

我正在使用forEach循环遍历两个数组（蛋糕和结霜）。警报确认预期结果。如何将结果添加到第3个数组？（cakeOptions）这个小提琴展示了到目前为止的工作： http://jsfiddle.net/_StephenC/ov5syuwb/20/

由于

function CakeController($scope) {
$scope.cakes = [{
    name: 'chocolate',
    'price': 6
}, {
    name: 'yellow',
    'price': 5
}, {
    name: 'coconut',
    'price': 7
}
];
$scope.frostings = [{
    'name': 'chocolate',
        'price': 5
},

{
    'name': 'vanilla',
        'price': 5
}, {
    'name': 'coconut',
        'price': 8
}];

$scope.cakeOptions = [];

angular.forEach($scope.cakes, function (value, key) {
var thisCake = JSON.stringify(value.name);
angular.forEach($scope.frostings, function (value) {
var thisFrosting = JSON.stringify(value.name, value.value);
alert(thisCake + ' cake with ' + thisFrosting + ' frosting');

我创建了一个实际上有效的新小提琴，并添加了从组合数组中填充第三个框的示例：

JSFiddle

<强> HTML

<div ng-app="cakeApp">
    <div ng-controller="cakeCtrl">
        <div id="one"><strong>Cakes</strong><br>
            <div class="order" ng-repeat="cake in cakes">
                {{cake.name}}
            </div>
        </div>
        <div id="two"><strong>Frostings</strong><br>
            <div class="order" ng-repeat="frosting in frostings">
                {{frosting.name}}
            </div>
        </div>
            <div id="three"><strong>Combinations</strong><br>
            <div class="order" ng-repeat="cakeOption in cakeOptions">
                {{cakeOption}}
            </div>
        </div>
    </div>
</div>

<强> JAVASCRIPT：

var app = angular.module('cakeApp', []);
app.controller('cakeCtrl', ['$scope', function($scope) {
    $scope.cakes = [{
        name: 'chocolate',
        price: 6
    }, {
        name: 'yellow',
        price: 5
    }, {
        name: 'coconut',
        price: 7
    }];

    $scope.frostings = [{
        'name': 'chocolate',
            'price': 5
    },

    {
        'name': 'vanilla',
            'price': 5
    }, {
        'name': 'coconut',
            'price': 8
    }];
    $scope.cakeOptions = [];

    angular.forEach($scope.cakes, function (value, key) {
        var thisCake = JSON.stringify(value.name);
        angular.forEach($scope.frostings, function (value) {
            var thisFrosting = JSON.stringify(value.name, value.value);
            $scope.cakeOptions.push(thisCake + ' cake with ' + thisFrosting + ' frosting');
        });
    });
}]);

在Angular中，如何循环遍历两个数组以填充第三个？
