编辑/更新数组

Question

我正在使用angularjs处理数组。我可以使用push添加数组。但是，我不知道如何编辑现有数组。正如你所看到的，我有我的添加项的推送方法，这是正常的。但是我应该怎么处理编辑按钮？

这是我的代码。

jsonData

angular.module('app')
    .factory('WebApi', function () {
        var owners = [{
                value: "Amy",
                text: "Amy",
            }, {
                value: "Peter",
                text: "Peter"
            }, {
                value: "Jim",
                text: "Jim"
            }];

        var sex = [{
                value: "Male",
                text: "Male",
            }, {
                value: "Female",
                text: "Female"
            }];

        var country = [{
                value: "Canada",
                text: "Canada",
            }, {
                value: "US",
                text: "United States"
            }, {
                value: "China",
                text: "China"
            }];

        var tempData = [];
        var someDate = new Date();

        //Display 100 dummy item 
        for (var i = 0; i < 100; i++) {


            var selectedCountry = country[Math.floor((Math.random() * country.length))];
            var selectedSex = sex[Math.floor((Math.random() * sex.length))];
            var selectedOwners = owners[Math.floor((Math.random() * owners.length))];

            tempData.push({
                id: i,
                owners: selectedOwners.text,
                country: selectedCountry.text,
                sex: selectedSex.text,
            })
        }
        ;

        return {
            getAll: function () {
                return tempData;
            },
            getCountry: function () {
                return selectedCountry.text;
            },
            getSex: function () {
                return selectedSex.text;
            },
            getOwners: function () {
                return selectedOwners.text;
            }
        }

        editData: function(newData) {
            tempData = newData;
        }

    });

添加并保存按钮
