<ul ng-repeat="permission in permissions" ng-click="permission.assigned=!permission.assigned">
  <a class="list-group-item" ng-class="{active: permission.assigned, disable: permission.name=='default'}">
    <div class="row">
      <div class="col-md-3">
        <input type=checkbox aria-label="checkbox" ng-model="permission.assigned" ng-click="$event.stopPropagation()">
      </div>
      <div class="col-md-4">{{ permission.name }}</div>
      <div class="col-md-6">{{ permission.description }}</div>
    </div>
  </a>
</ul>

Answer 1

将以下内容添加到输入元素 - ng-disabled="permission.name === 'default'"。
