[英]Angular - routing why do I getting my controller 2 times called
I am using routing in angular app. 我在Angular应用中使用路由。 while the page loads, I am getting the controller function triggers 2 times.. 页面加载时,我得到了控制器功能触发2次。
How to avoid that or is it have any useful meaning to call 2 times? 如何避免这种情况,或者打电话两次有什么用呢?
any one help me and explain the mistake what i do? 有人可以帮助我并解释我的错误吗?
here is my html: //i use jade! 这是我的html://我用玉!
header
h1 Header
div.content(ng-controller="HomeController")
div(ng-view)
footer
h5 Footer
here is my js: 这是我的js:
var locations = angular.module('location', ['ngRoute']);
locations.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/', {
controller: 'HomeController',
templateUrl: 'views/home.html'
})
.when('/inbox/:name', {
controller: 'InboxController',
templateUrl: 'views/inbox.html'
})
.otherwise({redirectTo: '/'});
}]);
locations.controller('HomeController', ['$scope', function($scope){
console.log('hi'); // i am getting 2 times consoled! -why?
}]);
Because you have div.content(ng-controller="HomeController")
in your template. 因为您的模板中包含div.content(ng-controller="HomeController")
。 You don't need to explicitly define ng-controller
directive to your header template because It has already been associated using $routeProvider
您不需要为标头模板明确定义ng-controller
指令,因为它已经使用$routeProvider
进行了关联
