触发ng-show时调用函数？

我认为，最好监视绑定ng-
show的模型。

这是示例：

<div ng-app="myApp" ng-controller="myCtrl" ng-init="isDisplayed = true">    <div ng-show="isDisplayed">something</div>    <button ng-click="isDisplayed = !isDisplayed">Toggle</button></div>var myApp = angular.module('myApp', []).controller('myCtrl', function($scope, $log) {    $scope.$watch('isDisplayed', function(newValue, oldValue) {        if (newValue !== oldValue) { $log.log('Changed!');        }    });});
