ng-repeat列表出错：令牌“$ invalid”是意外的

Question

低于我的错误：

错误：[$ parse：syntax]语法错误：令牌＆＃39; $ invalid＆＃39;是意料之外的，期待[} {[＆＃39;有错误＆＃39;：myForm.am1-0。$ invalid}]第28栏的[}]，从[$ invalid}开始。

<div class="row nopadding" ng-repeat="worker in workers">
<div class="col-md-3 nopadding"><h5>{{worker.name}}</h5></div>
<div class="col-md-1 nopadding" ng-repeat="schedule in worker.schedules">
  <div class="row nopadding">
    <div class="col-md-6 nopadding" ng-class="{'has-error': myForm.am1-{{$index}}.$invalid}"><input class="form-control nopadding" type="text" name="am1-{{$index}}" ng-pattern="/(?:[01]\d|2[0123]):(?:[012345]\d)/" ng-model="schedule.am1"
   placeholder="HH:mm" required /></div>
    <div class="col-md-6 nopadding"><input class="form-control nopadding" type="text" name="am2-{{$index}}" ng-pattern="/(?:[01]\d|2[0123]):(?:[012345]\d)/" ng-model="schedule.am2"
   placeholder="HH:mm" required /></div>
  </div>
  <div class="row nopadding">
    <div class="col-md-6 nopadding"><input class="form-control nopadding" type="text" name="pm1-{{$index}}" ng-pattern="/(?:[01]\d|2[0123]):(?:[012345]\d)/" ng-model="schedule.pm1"
   placeholder="HH:mm" required /></div>
    <div class="col-md-6 nopadding"><input class="form-control nopadding" type="text" name="pm2-{{$index}}" ng-pattern="/(?:[01]\d|2[0123]):(?:[012345]\d)/" ng-model="schedule.pm2"
   placeholder="HH:mm" required /></div>
  </div>
  <div class="row nopadding">
    <div class="col-md-6 nopadding"><input class="form-control nopadding" type="text" name="pm2-{{$index}}" ng-pattern="/(?:[01]\d|2[0123]):(?:[012345]\d)/" ng-model="schedule.total"
   placeholder="HH:mm" required /></div>
   <div class="col-md-6 nopadding" />
  </div>
</div>
<div class="col-md-1 nopadding">40</div>
<div class="col-md-1 nopadding">aaaaa</div>

任何想法??
