在阵列角更新对象 [英] Angular update object in array

问题描述

我要更新一个对象数组中的对象。是否有另一种可能性比遍历所有项目，并更新其是匹配的人吗？当前code如下所示：

I wanna update an object within an objects array. Is there another possibility than iterating over all items and update the one which is matching? Current code looks like the following:

angular.module('app').controller('MyController', function($scope) {
    $scope.object = {
        name: 'test',
        objects: [
            {id: 1, name: 'test1'},
            {id: 2, name: 'test2'}
        ]
    };

    $scope.update = function(id, data) {
        var objects = $scope.object.objects;

        for (var i = 0; i < objects.length; i++) {
            if (objects[i].id === id) {
                objects[i] = data;
                break;
            }
        }
    }
});

推荐答案

的过滤器，在从阵列查找元件帮助，也可用于更新，直接在阵列中的元素。
在下面的code [0] - >是直接访问对象

Filters that help in finding the element from the array, can also be used to update the element in the array directly. In the code below [0] --> is the object accessed directly.
