问题描述
我正在使用cordova插件来处理方向.如果方向发生变化,我想更改为其他视图.因此,我尝试在$ scope中定义一个变量,并在UI上进行相关更改.这是我的代码
I am using cordova plugin to handle orientation. I want to change to a different view if orientation changes. So I try to define a variable in $scope and do related changes on UI. here is my code
window.addEventListener("orientationchange", function() {
$scope.orientation = screen.orientation;
});
我从cordova插件定位首页中引用的此代码段.但方向改变时,UI不会发生任何变化.我什至没有定义$ scope.orientation(我通过ng-show测试了)
this code snippet I referred from cordova plugin orientation homepage. but the UI doesn't have any change when orientation changes. I even got $scope.orientation undefined(I tested by ng-show)
这是怎么发生的?感谢您的帮助.
How did this happen? Thanks for any help.
推荐答案
使用$apply()
.
angular.element($window).on("orientationchange", function() {
$scope.orientation = screen.orientation;
$scope.$apply();
});
这使AngularJS框架知道发生了更改.
This lets the AngularJS framework know a change has occurred.
