本文介绍了Angular ui-router:未调用子状态控制器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在我的 Angular 应用程序中,我有以下路由结构:
.state('映射', {网址:'/映射',templateUrl: 'app/components/mapping/mapping.html',控制器:'MapCtrl 作为地图',摘要:真实,验证:真实}).state('mapping.all', {网址:'',templateUrl: 'app/components/mapping/partials/all.html',验证:真实}).state('mapping.project', {url: '/:projectName',templateUrl: 'app/components/mapping/partials/project.html',控制器:'ProjectCtrl 作为项目',验证:真实})
当访问 mapping
状态时,mapping.all
默认加载.它基本上显示了链接到 mapping.project 状态的项目列表,如下所示:
<a ui-sref="mapping.project({projectId: project.id, projectName: project.name})">...</a>
我想在访问 mapping.project
时调用 ProjectCtrl
以加载必要的数据,但它甚至从未加载过.在下面仅包含相关数据的代码段中,alert
消息永远不会弹出:
角度.module('watera').controller('ProjectCtrl', Controller);Controller.$inject = ['$stateParams', 'UserFactory', 'ProjectFactory'];功能控制器($stateParams,用户工厂,项目工厂){var proj = 这个;启用();功能激活(){警报('1');}}
js 文件链接正确,控制器命名正确.<div ui-view></div>
元素放置在 mapping.html
中,如下所示:
<div class="container-fluid"><div class="row"><div class="col-xs-12"><strong>映射</strong><p class="text-muted">在本节中...</p>
<div ui-view></div>
为什么这个控制器没有加载?
它变得更奇怪,我将结构切换为:
.state('映射', {网址:'/映射',templateUrl: 'app/components/mapping/mapping.html',摘要:真实,验证:真实}).state('mapping.all', {网址:'',templateUrl: 'app/components/mapping/partials/all.html',控制器:'MapCtrl 作为地图',验证:真实}).state('mapping.project', {url: '/:projectName',templateUrl: 'app/components/mapping/partials/project.html',控制器:'ProjectCtrl 作为项目',验证:真实})
虽然 MapCtrl
一直正常工作,但 ProjectCtrl
仍然没有.
解决方案
发现问题...本项目中有两个ProjectCtrl
实例:
显然,这会导致某种静默冲突,因为绝对没有控制台错误.由于第二个实例也在index.html
上链接,在 之后我想加载,它可能只是替换了正确的版本.调试噩梦.
现已修复.
In my Angular app, I have the following route structure:
.state('mapping', {
url: '/mapping',
templateUrl: 'app/components/mapping/mapping.html',
controller: 'MapCtrl as map',
abstract: true,
authenticate: true
})
.state('mapping.all', {
url: '',
templateUrl: 'app/components/mapping/partials/all.html',
authenticate: true
})
.state('mapping.project', {
url: '/:projectName',
templateUrl: 'app/components/mapping/partials/project.html',
controller: 'ProjectCtrl as proj',
authenticate: true
})
When accessing the mapping
state, mapping.all
loads by default. It basically shows a list of projects which link to the mapping.project state, as such:
<a ui-sref="mapping.project({projectId: project.id, projectName: project.name})">...</a>
I want to call the ProjectCtrl
when I access mapping.project
in order to load the necessary data, but it never even gets loaded. In the snippet below which includes only relevant data, the alert
message never pops up:
angular
.module('watera')
.controller('ProjectCtrl', Controller);
Controller.$inject = ['$stateParams', 'UserFactory', 'ProjectFactory'];
function Controller($stateParams, UserFactory, ProjectFactory) {
var proj = this;
activate();
function activate() {
alert('1');
}
}
The js file is correctly linked and the controller is named correctly. The <div ui-view></div>
element is placed within mapping.html
, as seen below:
<div id="ribbon" class="no-print">
<div class="container-fluid">
<div class="row">
<div class="col-xs-12">
<strong>Mapping</strong>
<p class="text-muted">In this section...</p>
</div>
</div>
</div>
</div>
<div ui-view></div>
Why is this controller not loading?
EDIT: It gets weirder, I switched the structure to:
.state('mapping', {
url: '/mapping',
templateUrl: 'app/components/mapping/mapping.html',
abstract: true,
authenticate: true
})
.state('mapping.all', {
url: '',
templateUrl: 'app/components/mapping/partials/all.html',
controller: 'MapCtrl as map',
authenticate: true
})
.state('mapping.project', {
url: '/:projectName',
templateUrl: 'app/components/mapping/partials/project.html',
controller: 'ProjectCtrl as proj',
authenticate: true
})
And while MapCtrl
keeps working correctly, ProjectCtrl
still doesn't.
解决方案
Found the issue... There were two instances of ProjectCtrl
in this project:
Apparently, this causes some sort of silent conflict because there was absolutely no console error. Since the second instance was also linked on index.html
, after the one that I wanted to load, it was probably simply replacing the correct version. Debugging nightmare.
Fixed now.
