我必须从我的控制器中的表中删除一个项目问题是我没有使用作用域，我使用的是函数控制器。如果我试图添加一个函数，就会崩溃并给出错误。

希望你们能帮我

homeController:

// homeController.js

(function () {
    'use strict';
    angular.module('myApp')
        .controller('homeController', homeController);

    function homeController() {
        var vm = this;
        vm.autos = [
            {id: 1, 'Omschrijving': 'A 180', Prijs: '24.242 € ', Type: 'A'},
            {id: 2, 'Omschrijving': 'A 180 CDI BlueEFFICIENCY', Prijs: '26.015 € ', Type: 'A'},
            {id: 3, 'Omschrijving': 'B 200 CDI BlueEFFICIENCY', Prijs: '30.129 € ', Type: 'B'},
            {id: 4, 'Omschrijving': 'C 250 CGI BlueEFFICIENCY', Prijs: '40.414 € ', Type: 'C'},
            {id: 5, 'Omschrijving': 'C 300 CDI 4MATIC BlueEFFICIENCY', Prijs: '48.642 € ', Type: 'C'},
            {id: 6, 'Omschrijving': 'C 350 CGI 4MATIC BlueEFFICIENCY', Prijs: '50.941 € ', Type: 'C'},
            {id: 7, 'Omschrijving': 'CL 500 CDI 4MATIC BlueEFFICIENCY', Prijs: '129.954 € ', Type: 'CL'},
            {id: 8, 'Omschrijving': 'CL 600', Prijs: '170.489 € ', Type: 'CL'}
        ];
    }

};
})();

home.html

<div>
    <table style="text-align: left;">
    <th>
    Omschrijving
    </th>
    <th>
    Prijs
    </th>
    <th>
    Type
    </th>
        <tr ng-repeat="autos in homeCtrl.autos">
        <td width="75%">
            <a ng-href="#/detail/{{autos.id}}">
            {{ autos.Omschrijving }}
            </a>
            </td>
            <td width="25%">
            {{ autos.Prijs }}
            </td>
            <td width="25%">
            {{ autos.Type}}
            </td>
            <td>
            <a ng-click="delete(something)">Delete</a>
            </td>
        </tr>
    </table>
    <a href="#/add">Auto Toevoegen</a>
</div>

所以基本上，我只需要知道如何在我的视图和控制器中添加一个函数来删除一个项目。

    // homeController.js

(function () {
    'use strict';
    angular.module('myApp')
        .controller('homeController', homeController);

    function homeController() {
        var vm = this;
        vm.autos = [
            {id: 1, 'Omschrijving': 'A 180', Prijs: '24.242 € ', Type: 'A'},
            {id: 2, 'Omschrijving': 'A 180 CDI BlueEFFICIENCY', Prijs: '26.015 € ', Type: 'A'},
            {id: 3, 'Omschrijving': 'B 200 CDI BlueEFFICIENCY', Prijs: '30.129 € ', Type: 'B'},
            {id: 4, 'Omschrijving': 'C 250 CGI BlueEFFICIENCY', Prijs: '40.414 € ', Type: 'C'},
            {id: 5, 'Omschrijving': 'C 300 CDI 4MATIC BlueEFFICIENCY', Prijs: '48.642 € ', Type: 'C'},
            {id: 6, 'Omschrijving': 'C 350 CGI 4MATIC BlueEFFICIENCY', Prijs: '50.941 € ', Type: 'C'},
            {id: 7, 'Omschrijving': 'CL 500 CDI 4MATIC BlueEFFICIENCY', Prijs: '129.954 € ', Type: 'CL'},
            {id: 8, 'Omschrijving': 'CL 600', Prijs: '170.489 € ', Type: 'CL'}
        ];
        vm.delete = function(id){
            // delete vm.autos[id];
           vm.autos.splice(id-1, 1); // this is better
        }
    }

})();

home.html

<div>
    <table style="text-align: left;">
    <th>
    Omschrijving
    </th>
    <th>
    Prijs
    </th>
    <th>
    Type
    </th>
        <tr ng-repeat="autos in homeCtrl.autos">
        <td width="75%">
            <a ng-href="#/detail/{{autos.id}}">
            {{ autos.Omschrijving }}
            </a>
            </td>
            <td width="25%">
            {{ autos.Prijs }}
            </td>
            <td width="25%">
            {{ autos.Type}}
            </td>
            <td>
            <a ng-click="homeCtrl.delete(autos.id)">Delete</a>
            </td>
        </tr>
    </table>
    <a href="#/add">Auto Toevoegen</a>
</div>
