Question

我已经阅读过Angular中的ng-repeat和表格，但我仍然无法弄明白。

我的HTML代码如下：

<div class="container">
<h3>table</h3>
    <table>
        <tr ng-repeat="car in userCars">
            <td>{{ car }}</td>
        </tr>
    </table>
</div>

我的控制器看起来像那样：

app.controller('ManageCarsController', function ($scope, $location, UserService) {
    'use strict';
    (function () {
        console.log('code is getting here');
        $scope.userCars = [1,2,3];
        $scope.UserService = UserService;
    })();

它会留下一张空表。但是如果我将代码更改为这样，它可以正常工作（但这对我的使用不利）：

app.controller('ManageCarsController', function ($scope, $location, UserService) {
    'use strict';
    $scope.userCars = [1,2];
    (function () {
        $scope.UserService = UserService;
    })();

我不认为IIFE（立即调用的函数表达式）可以帮助您。你可能应该完全删除它，这反过来会使一切正常对你

app.controller('ManageCarsController', function ($scope, $location, UserService) {
$scope.userCars = [1,2];
$scope.UserService = UserService;

如果你真的想使用IIFE，你应该将整个代码放在其中

'use strict';
(function () {
app.controller('ManageCarsController', function ($scope, $location, UserService) {
'use strict';
$scope.userCars = [1,2];
    $scope.UserService = UserService;
})();

ng-repeat无法识别范围数据
