我有一个调用控制器中的函数的按钮。单击按钮时，它正在更新变量buttonDisplay的值，但该值不会在视图中更新。
<button type="button" class="btn btn-default btn-lg navButton" aria-label="Center Align" ng-controller = "buttonViewCtrl" ng-click="nav()">
<span class="glyphicon glyphicon-align-justify" aria-hidden="true"></span>
</button>
<div ng-controller = "buttonViewCtrl"> My name is {{buttonDisplay}} </div>
控制器
.controller('buttonViewCtrl', [ '$scope', function($scope) {
$scope.buttonDisplay = 0;
$scope.nav = function() {
$scope.buttonDisplay++;
};
对于上下文，我在下面为我的整个应用程序提供代码。

您在该页面上多次声明ngController次。这不会创建一个共享实例，但会创建许多独立实例。将您的元素包装在容器中，然后使用ngController：
<div ng-controller="buttonViewCtrl">
<button type="button" class="btn btn-default btn-lg navButton" aria-label="Center Align" ng-click="nav()">
<span class="glyphicon glyphicon-align-justify" aria-hidden="true"> </span>
</button>
<div> My name is {{buttonDisplay}} </div>
</div>

这是您的预期功能：plunkr
相关代码：
<button type="button" class="btn btn-default btn-lg navButton" aria-label="Center Align" ng-click="nav()">
<span class="glyphicon glyphicon-align-justify" aria-hidden="true"></span>
</button>
<div> My name is {{buttonDisplay}} </div>
我不确定你究竟遇到了什么问题，但这可能是不必要的ng-controller指令。

您不必拥有多个控制器定义，必须像这样包装
<div ng-controller="buttonViewCtrl">
<button type="button" class="btn btn-default btn-lg navButton" aria-label="Center Align" ng-click="nav">
<span class="glyphicon glyphicon-align-justify" aria-hidden="true"></span>
</button>
My name is {{buttonDisplay}}
</div>
