Question

我没有得到预期的输出，我得到了绑定表达式而不是名称，如下所示

预期输出：

UK
 London
 Manchestor
 Bringham
US
 Dallas
 Austin
 San Antonio
India
 HYD
 BLR
 DLH

输出：

{{country.name}} 
  {{city.name}}

这是我的编码。如果我有任何错误，请告诉我。

Answer 1

如果您的角应用程序在script.js中，请检查导入脚本的顺序。您应该在导入angularjs后导入它！按此顺序：

<script src="angular.min.js"></script>
<script src="Script.js"></script>

Answer 2

我认为没关系但是将script.js的导入移动到body标签或者在角度导入之后。

我运行了你的代码并且它有效。 angular.min.js在同一个文件夹中吗？由于库未加载，很可能是您遇到了问题

AngularJS使用ng-repeat。绑定表达式不起作用
