javascript - 如何在 Angular js中的现有数组中添加新键？

Question

我定义了空白数组 $scope.order，在表单上提交数据获取并创建新数组，然后与现有数组合并。

.controller('GuestDetailsCtrl',function($scope){
    $scope.order = [];
    $scope.itemDetails = function() {
        // Here data get after form submiti have array arrieve from form submit.
        $scope.order=$scope.order.push({name:$scope.item.name,price:$scope.item.price});
    }
});

我想要这样的结果。

$scope.order = [{name:'abc',price:100},{name:'pqr',price:80},{name:'xyz',price:50}];

When itemDetails() call at that time array merge with new data.

push 对数组进行就地操作。简单

$scope.order = [];
$scope.itemDetails = function() {
    // Here data get after form submiti have array arrieve from form submit.
    $scope.order.push({name:$scope.item.name,price:$scope.item.price});
}

(不分配它)，这应该可以!
