问题描述
$locationChangeSuccess 和 $locationChangeStart 有什么区别?
它们都是与 window.location 相关的未记录事件.
They are both undocumented events related to window.location.
推荐答案
$locationChangeStart 在 AngularJS 开始根据通过 $location 完成的更改更新浏览器位置时触发服务($location.path(), $location.search()).
The $locationChangeStart is fired when AngularJS starts to update browser's location based on mutations done via $location service ($location.path(), $location.search()).
应用程序可能会侦听 $locationChangeStart 事件并对其调用 preventDefault().在这种情况下，第二个事件 ($locationChangeSuccess) 将不会广播.
It might happen that an application will listen to the $locationChangeStart event and will call preventDefault() on it. In this case the second event ($locationChangeSuccess) won't be broadcasting.
简而言之:$locationChangeStart 在位置更新时触发.如果没有阻止第一个操作，则后面跟着 $locationChangeSuccess.
In short: $locationChangeStart fires when the location gets updated. It is followed by $locationChangeSuccess if the first action wasn't prevented.
