如何在一个视图的控制器之间切换 angular js
How can I switch between controllers for one view angular js
我有一个 angular 应用 with one main view
和 two main controllers
我想 toggle between
这两个控制器 depending on the button click.
[=24 如何实现=]js?
完整说明:
我有一个包含一些动态文本和图表的网页。我想要英语和德语两种语言。基本上,如果语言切换为英语,我希望一个控制器更改英文文本,而另一个控制器切换为德语。我试过 Angular Translate 但我不确定如何使用它来翻译从函数返回的值,所以决定通过控制器更改它。
我通过下面的 ui-router 代码更新页面
function routerConfig($stateProvider, $urlRouterProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$stateProvider
.state('home', {
url: '/',
templateUrl: 'app/main/main.html',
controller: 'MainController',
controllerAs: 'main'
})
.state('line', {
url: '/lineChart',
templateUrl: 'app/simplerChart/simplerChart.html',
controller: 'SimpleChartController'
});
我们有两条路线和两个控制器绑定到每条路线。您可以在两条路线之间切换:/english
和 /german
。两者都有不同的控制器,都有不同的模板。
1) 如果您单击 "First View",您将被带到 URL“#/english”,在那里您绑定了 MainFirstCtrl
这个 HTML:
<div style="background: mediumpurple">{{ctrl.title}}</div>
2) 如果您单击 "First View",您将被带到 URL“#/english”,在那里您绑定了 MainSecondCtrl
这个 HTML:
<div style="background: yellowgreen">{{ctrl.title}}</div>
3) 现在使用 ui-sref 你可以改变状态:
<button type="button" ui-sref="first">Go to First View (/english)</button>
<button type="button" ui-sref="second">Go to Second View (/german)</button>
4) 状态在 ui-路由器配置中定义如下:
$stateProvider.state('first', {
url: '/first',
template: '<div style="background: mediumpurple">{{ctrl.title}}</div>',
controller: 'MainFirstCtrl',
controllerAs: 'ctrl'
});
下面的工作示例:
var myapp = angular.module('myapp', ['ui.router']);
//Here are our routes defined
myapp.config(['$stateProvider', function ($stateProvider) {
$stateProvider.state('first', {
url: '/english',
template: '<div class="view" style="background: mediumpurple">{{ctrl.title}}</div>',
controller: 'MainFirstCtrl',
controllerAs: 'ctrl'
});
$stateProvider.state('second', {
url: '/german',
template: '<div class="view" style="background: yellowgreen">{{ctrl.title}}</div>',
controller: 'MainSecondCtrl',
controllerAs: 'ctrl'
});
}]);
//Here are our two different controllers that would control the same view BUT with different routes
myapp.controller('MainFirstCtrl', ['$scope', function($scope) {
this.title = 'This is english view';
}]);
myapp.controller('MainSecondCtrl', ['$scope', function($scope) {
this.title = 'This is german view';
}]);
button {
background: #1e6791;
border: 0;
color: #fff;
padding: 15px 20px;
font-family: arial;
font-size: 15px;
margin: 15px 0px;
box-shadow: 0px 0px 1px rgba(0,0,0,.3);
}
.view {
width:300px;
height:150px;
}
