我已经尝试过编译和指令，但我没有到任何地方。示例中的编译代码直接从有角度的网站上删除，但我不知道如何使用它。任何指导都非常感激。

I have tried compile and directives but I'm not getting anywhere. the compile code in the example is ripped straight off the angular website but i've no idea how to use it. Any guidance much appreciated.

推荐答案

你正在绊倒 ng-repeat 创建一个新的范围。所以您的更新仅在子范围内发生，不会显示在父范围内。

You are tripping over the fact that ng-repeat creates a new scope. So your updates are happening in the child scope only and not showing up in the parent scope.

您可以在此视图中执行此操作：

You could do something like this in your view:

<div ng-repeat="name in names">
  <input ng-model="name.name" ng-click="changeName($index)" value="{{ name.name }}">
</div>

$ index 然后在你的控制器中：

$index in the 0 based counter. Then in your controller:

$scope.changeName = function($index) {
    $scope.names[$index].name = $scope.nameselected;
};
