Angularjs切换图像onclick

Question

我正在尝试在用户点击它时切换按钮图像.如果可能的话,我更喜欢使用angularjs而不是jquery.现在我有一个可以在点击时切换图像的工作版本,唯一的问题是它会在点击时更改所有图像.如何缩小范围或传递img元素的src属性？

    <div ng-repeat="merchant in merchants">
      <div class="followrow">
        <a ng-click="toggleImage()"><img id="followbutton" ng-src="{{followBtnImgUrl}}"  /></a>
      </div>
    </div>

app.controller('FollowCtrl', function CouponCtrl($scope) {
    $scope.followBtnImgUrl = '/img1'


    $scope.toggleImage = function () {
        if ($scope.followBtnImgUrl === '/img1.jpg') {
            $scope.followBtnImgUrl = baseUrl + '/img2.jpg';
        } else {
            $scope.followBtnImgUrl = 'img1.jpg';
        }
    }
});

我可以将img src属性传递给toggleImage(this.img.src)或类似的函数吗？

<div ng-repeat="merchant in merchants">
  <div class="followrow">
    <a ng-click="toggleImage(merchant)"><img id="followbutton" ng-src="{{merchant.imgUrl}}"  />
    </a>
  </div>
</div>

.

app.controller('FollowCtrl', function CouponCtrl($scope) {
    $scope.followBtnImgUrl = '/sth.jpg'
    $scope.merchants = [{imgUrl: "img1.jpg", name:"sdf"}, 
                         {imgUrl: "img2.jpg", name: "dfsd"}];


     $scope.toggleImage = function(merchant) {
         if(merchant.imgUrl === $scope.followBtnImgUrl) {
             merchant.imgUrl = merchant.$backupUrl;
         } else {
             merchant.$backupUrl = merchant.imgUrl;
             merchant.imgUrl = $scope.followBtnImgUrl;
         }
    };
});
