我用我的角角的应用程序UI的路由器。对于路由部分,我已经写了
I'm using angular ui-router in my angular application. For the routing part I've written
var routerApp = angular.module('routerApp', ['ui.router']); routerApp.config(function($stateProvider, $urlRouterProvider) { $urlRouterProvider.otherwise('/home'); $stateProvider // HOME STATES AND NESTED VIEWS ======================================== .state('home', { url: '/home', templateUrl: 'partial-home.html', controller : function($scope,$state){ $scope.$on('$viewContentLoaded', function(){ console.log("home content loaded",$state.current); }) } }) // nested list with custom controller .state('home.list', { url: '/list', template: 'I am using a list.' }) // nested list with just some random string data .state('home.paragraph', { url: '/paragraph', template: 'I could sure use a drink right now.' }) });在局部home.html做为我wriiten: -
In partial-home.html I've wriiten:-
<div class="jumbotron text-center"> <h1>The Homey Page</h1> <p>This page demonstrates <span class="text-danger">nested</span> views.</p> <a ui-sref=".list" class="btn btn-primary">List</a> <a ui-sref=".paragraph" class="btn btn-danger">Paragraph</a> </div> <div ui-view></div>现在,当我执行这个程序在浏览器中,如果我开的路线
Now when I'm executing this app in browser, if I open the the route
/home浏览器控制台显示出家庭内容加载一次,然后如果我点击列表中的链接,地址栏变为
The browser console is showing "home content loaded" once, and then if I click on the list link, the addressbar changes to
/home/list然后还控制台显示一次。
And then also the console is shown once.
但是,如果我刷新浏览器选项卡在那个时候(当路线是家庭/列表),控制台显示的两倍。请帮我,为什么这件事情发生了。
But if I refresh the browser tab at that time (when the route is home/list), the console is shown twice. Please help me why this thing happening.
推荐答案由于home.list一种家的孩子的状态,当你重新加载页面home.list它首先初始化视图家居控制器比查看列表控制器,所以$ viewContentLoaded被调用两次
because home.list is a child state of home and when you reload page for home.list it first initializes view of home controller than view of list controller so $viewContentLoaded is called twice
我猜你使用这会导致孩子和家长共享相同的范围家里模板中的UI视图。 u的聆听双方的孩子和家长的范围事件。所以很自然地被调用两次
i guess that you use ui-view inside home template which causes child and parent to share the same scope. u are listening to both child's and parent's scope for the event. so it is natural to be called twice
