angularjs – Angular TypeError：name.replace不是ng-style的函数

我是角色的新手并且在控制台TypeError中不断收到以下错误：name.replace不是函数.我不确定究竟是什么导致它,但它似乎是由ng风格的声明引起的,也许与camelCase有关？ @H_262_1@我不明白的部分是为什么ng-style =“isFrontView()||！匹配&& {‘display’：’none’}”抛出错误,但ng-style =“！isFrontView()| |！matches&& {‘display’：’none’}“不会抛出错误.

@H_262_1@为了解决这种情况,我尝试从函数名中删除camelCase并全部小写.我也尝试使用!! isFrontView(),但似乎都没有删除错误消息.

@H_262_1@有谁知道这个错误消息的原因和潜在的修复？

@H_262_1@HTML模板：

<div class="system-view">
    <div class="controller-container fill" id="systemView1" ng-style="isFrontView() || !matches && {'display': 'none'}">
        <canvas id="canvasLayer-sHell" data-layername="front" width="617" height="427"></canvas>
        <i ng-if="!matches" class="fa fa-repeat toggle-view" ng-click="changeView()" ng-touch="changeView()"></i>
    </div>
    <div class="controller-container fill" id="systemView2" ng-style="!isFrontView() || !matches && {'display': 'none'}">
        <canvas id="canvasLayer-sHell" data-layername="BACk" width="617" height="427"></canvas>
        <i ng-if="!matches" class="fa fa-undo toggle-view" ng-click="changeView()" ng-touch="changeView()"></i>
    </div>
</div>

@H_262_1@后端代码：

$scope.frontView = true;
$scope.matches = true;

$scope.isFrontView = function() {
   return $scope.frontView;
};

$scope.changeView = function() {
    $scope.frontView = !$scope.frontView;
};

@H_262_1@附：即使控制台出错,一切仍然正常.
