How many ng-App attributes can be declared in in Angular JS? and under what circumstances?
据我所知，ng-app 用于 Angular JS 应用程序的自动引导。
最佳答案
http://docs.angularjs.org/api/ng.directive:ngApp
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.
TL; DR:你可以有多个，但只有第一个会被引导。
