用于$ js的$ scope的console.log
Mad*_*d-D 3 javascript angularjs angularjs-scope console.log angularjs-controller
为什么我无法控制输出$ scope值？我正在尝试从页面中提取用户指定的值并在控制器中检索.最终我想将此传递给服务,以便多个控制器可以访问这些数据.

<h4> This is what you entered : {{ name }} </h4>
<h4 style=color:red> now filtering: {{ lower() }}</h4>

APP.JS
var myApp = angular.module('myApp', []);
myApp.controller('mainController', ['$scope', '$filter', function($scope, $filter) {
$scope.name = 'Test ';
$scope.lower = function(){
return $filter('lowercase')($scope.name);
}
$scope.name = $scope.lower();
console.log($scope.name);
console.log($scope.lower());
}]);
控制台将在初始化时输出值,但不会在用户进行更改后输出.

您需要观察范围变量:
$scope.$watch('name', function() {
console.log($scope.name);
});
