  <div class="col-md-4 text-right">
      <a ng-class="campaign_range === 'thismonth' ? 'btn btn-blue' :  'btn btn-link'" href="#" ng-click='change_range("thismonth")'>This Month</a>
      <a ng-class="campaign_range === 'all' ? 'btn btn-blue' :  'btn btn-link'" href="#" ng-click='change_range("all")'>All Time</a>
  </div>

控制器

  $scope.campaign_range = "all";
  $scope.change_range = function(range) { 
        if (range === "all")
        {
            $scope.campaign_range = "all"
        }
        else
        {  
            $scope.campaign_range = "thismonth"
        }
  };

这就像一个魅力;)

<ul class="nav nav-pills" ng-init="selectedType = 'return'">
    <li role="presentation" ng-class="{'active':selectedType === 'return'}"
        ng-click="selectedType = 'return'"><a href="#return">return

    </a></li>
    <li role="presentation" ng-class="{'active':selectedType === 'oneway'}"
        ng-click="selectedType = 'oneway'"><a href="#oneway">oneway
    </a></li>
</ul>

三元运算符刚刚在1.1.5中被添加到角解析器中。

所以最简单的方法就是:

ng:class="($index==selectedIndex)? 'selected' : ''"

这里有一个更简单的解决方案:

function MyControl($scope){ $scope.values = ["a","b","c","d","e","f"]; $scope.selectedIndex = -1; $scope.toggleSelect = function(ind){ if( ind === $scope.selectedIndex ){ $scope.selectedIndex = -1; } else{ $scope.selectedIndex = ind; } } $scope.getClass = function(ind){ if( ind === $scope.selectedIndex ){ return "selected"; } else{ return ""; } } $scope.getButtonLabel = function(ind){ if( ind === $scope.selectedIndex ){ return "Deselect"; } else{ return "Select"; } } } .selected { color:red; } <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script> <div ng-app ng-controller="MyControl"> <ul> <li ng-class="getClass($index)" ng-repeat="value in values" >{{value}} <button ng-click="toggleSelect($index)">{{getButtonLabel($index)}}</button></li> </ul> <p>Selected: {{selectedIndex}}</p> </div>

这是我在工作中多次有条件的判断:

<li ng-repeat='eOption in exam.examOptions' ng-class="exam.examTitle.ANSWER_COM==exam.examTitle.RIGHT_ANSWER?(eOption.eoSequence==exam.examTitle.ANSWER_COM?'right':''):eOption.eoSequence==exam.examTitle.ANSWER_COM?'wrong':eOption.eoSequence==exam.examTitle.RIGHT_ANSWER?'right':''">
  <strong>{{eOption.eoSequence}}</strong> &nbsp;&nbsp;&nbsp;&nbsp;|&nbsp;&nbsp;&nbsp;&nbsp;
  <span ng-bind-html="eOption.eoName | to_trusted">2020 元</span>
</li>
