Question

I just started learning Angular, and when I tried to write a small demo, I got an error. . .

html:

js:

Error report:

------New error message= =#----

Rewritten according to @张博汉's method

Still getting the same error

Then I put ng-app="myApp"

Reported a new error T^T

Answer 1

Cannot be used directlyfunction来定义controller

var myApp = angular.module('myApp',[]);

myApp.controller('GreetingController', ['$scope', function($scope) {
  $scope.greeting = 'Hola!';
}]);

Reference: https://docs.angularjs.org/guide/controller
