我开始学习Express和Angularjs。在项目中,我想在服务器端呈现HTML并通过Angularjs绑定数据,但它不起作用。我在浏览器中看到ng-repeat被禁用
<body ng-app="photoApp" class="ng-scope">
<h1>Express</h1>
<p>Welcome to Express</p>
<!-- ngView: -->
<div ng-view="" class="ng-scope">
<div id="photos" class="ng-scope">
<!-- ngRepeat: photo in vm.photos -->
</div>
</div>
</body>
,因此没有显示数据。请帮我解决这个问题,谢谢先进!
