我正在尝试使用ng-options用一些数字填充select。这是我的代码：

Select始终为空。

您尚未关闭控制器。在$scope.changeFont函数后添加});。

此外，在发布问题之前，请格式化您的代码。对于那些试图帮助你的人来说，这是一场噩梦，它可以帮助你发现这样的问题。

编辑

在$scope.changeFont函数中，有一行if(fontSize == $scope.)。我想你希望它是if(fontSize == $scope.FontSize)。我在下面的代码段中对其进行了更改，并填充了<select>。$scope.changeFont是否按您的意愿工作，我不知道，它不在这个问题的范围内。

此外，在HTML中，您需要移动<select>中的<input>。
