This error occurs in angular because the controller was not introduced and is modified as follows:

Only need to add a controller to the module

<Script>    varapp=Angular.module ('MyApp',['Ngroute']); App. Config (['$routeProvider',function($routeProvider) {$routeProvider. When (' /Home', {templateurl:'home.html', Controller:"'        }). When ('/cn', {templateurl:'cn.html', Controller:"'        }). When ('/other', {templateurl:'other.html', Controller:"'        }). Otherwise ({redirectto:' /Home'})}]) App.controller ('Myctrl',function($scope) {})</Script>
