例如,我有这么简单的片段:
var sampleApp = angular.module('sampleApp', []);
sampleApp.config(['$routeProvider',
function($routeProvider, $rootScope) {
$routeProvider.
when('/AddNewOrder', {
templateUrl: 'add_order.html',
controller: 'AddOrderController'
}).
when('/ShowOrders', {
templateUrl: 'show_orders.html',
controller: 'ShowOrdersController'
}).
otherwise({
redirectTo: '/AddNewOrder'
});
}]);
sampleApp.controller('AddOrderController', function($scope, $rootScope) {
$scope.message = 'This is Add new order screen';
$scope.$on('$viewContentLoaded', function (event, toState, toParams, fromState, fromParams) {
console.log("Add new order");
});
});
sampleApp.controller('ShowOrdersController', function($scope,$rootScope) {
$scope.message = 'This is Show orders screen';
$scope.$on('$viewContentLoaded', function (event, toState, toParams, fromState, fromParams) {
console.log("Show orders");
});
});
它是来自ng示例的app.js,在浏览器中它的示例看起来如此:

哪里有些奇怪:
$scope.$on('$viewContentLoaded', function (event, toState, toParams, fromState, fromParams) {
console.log("Add new order");
和
$scope.$on('$viewContentLoaded', function (event, toState, toParams, fromState, fromParams) {
console.log("Show orders");
});
每次点击链接时都会调用两次。 我也尝试使用'$ routeChangeSuccess',但结果相同。 为什么会这样? 需要做些什么才能获得$ scope的调用。$ on(..)?
答案 0 :(得分:2)
将您的href="#AddNewOrder"
更改为href="#/AddNewOrder"
。
因为你的控制器初始化了两次。
