我正在尝试使用 angularJS 重复 3 行的 div 卡。但是，它似乎不起作用。它不是在行中显示卡片，而是显示纯 html，其中 {{ }} 中的对象关键字以普通方式显示。这是所有相关代码。

最佳答案
您在 Controller 中使用 $scope 并在 HTML 中使用 Controller as 语法。
按照任一方式，为了使用 $scope 变量，请将 HTML 更改为，
<div ng-controller="lineController">
<div class="row" ng-repeat="line in linesList track by $index" ng-if="$index % 3 == 0">
<div class="col-md-4" ng-repeat="i in [$index, $index + 1, $index + 2]" ng-if="linesList[i] != null">
<div class="card">
<div class="card-header">
{{line.name}}
</div>
<div class="card-body">
<p class="card-text">{{line.description}}</p>
<ul class="list-group list-group-flush">
<li class="list-group-item">Time: {{line.time}}</li>
<li class="list-group-item">Number of People: {{line.numPeople}}</li>
<li class="list-group-item"><a href="#" class="card-link">Card link</a></li>
</ul>
</div>
</div>
</div>
</div>
</div>
