Angularjs: highlight a button on click - 


       <tbody md-body>           <tr md-row md-select="dessert"  md-select-id="name" ng-model="participant.partname" md-auto-select ng-repeat="participant in participants track participant.partname | filter: search">             <td md-cell>{{participant.partname}}</td>              <td md-cell><img src="./images/mute.png" ng-click="mutepart(participant.partname);" title="mute"                                  ng-class="{'selected-image' : participant.partname === muteselected}" /></td>             <td md-cell><img src="./images/unmute.png"  ng-click="unmutepart(participant.partname);" title="unmute"                                  ng-class="{'selected-image' : participant.partname === unmuteselected}"/></td>                              </tr>         </tbody>

js:

$scope.mutepart = function(muteselected) {            $scope.muteselected = muteselected;   $scope.unmuteselected = null;   $rootscope.muteind = true;   $rootscope.muted = true;  }  $scope.unmutepart = function(unmuteselected) {   $scope.unmuteselected = unmuteselected;   $scope.muteselected = null;   $rootscope.mutind = false;   $rootscope.muted = false; }

css: .selected-image { border: 1px solid red; }
