为什么不隐藏元素ng-hide？

Question

如果value为零，我需要隐藏元素。我试过了：

<span ng-hide="currentCount.appointment == 0">{{currentCount.appointment}}</span>

在console.log(currentCount.appointment)我看到currentCount.appointment的更改值为零后，为什么span块不会隐藏？

完整代码：

request.success(function () {

$scope.currentCount = CounterNotificationService.setCounterInc('appointment', 'decr');
console.log($scope.currentCount.appointment);
});

Answer 1

似乎有效，

{{currentCount.appointment == 0}}

评估为

true

我使用ng-hide和ng-class方法创建了a fiddle

Answer 2

试试这个：

<span ng-hide="currentCount.appointment == '0'">{{currentCount.appointment}}</span>
