推荐答案

在您的controller中，使用

In your controller use $watch to check the return value of isOpen():

  $scope.$watch(
    function () {
      return $mdSidenav('left').isOpen();
    },
    function (newValue, oldValue) {
      console.log(newValue);
      if (newValue == false) {
        var button = angular.element(document.querySelector('#navButton'))
        button.removeAttr('md-focused')
      }
    });
