新建expression_scope.js页面：
/**
* Created by 奔跑的阿甘
*/
angular.module('myApp',[]).controller('myController',function ($scope) {
$scope.speed = 'Slow';
$scope.vehicle = "Train";
$scope.newSpeed = 'Hypersonic';
$scope.newVehicle = 'Plane';
$scope.upper = function (aString) {
return angular.uppercase(aString);
};
$scope.lower = function (aString) {
return angular.lowercase(aString);
};
$scope.setValues = function (speed,vehicle) {
$scope.speed = speed;
$scope.vehicle = vehicle;
};
});
