Question

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。

Answer 1

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>
