我正在使用ui路由器创建多页表单。在表单的第一部分中,用户将选择一个按钮。此按钮的值将用于对第二页上加载的表进行排序。我以为可以用ng-click设置/更新按钮的值,但它没有保存。第二页不按更新值排序。
我的具体问题是在firstPage.html中-单击ng-button时。 sortType的原始值为:sortType = ''
。我的计划是在此页面上设置我的sortType值。这是我的方法:
<a ui-sref="orderForm.step2"
ng-click="sortType ='name'"
class="btn btn-block btn-info">
我以为
ng-click="sortType ='name'"
将更新并保存sortType值。但是,当第二页仍然是:sortType= ''
。你们中的任何人对如何解决此问题有建议吗?谢谢!这是我的firstPage.html:
<div class="form-group row" ng-controller="formController">
<div class="col-xs-6 col-xs-offset-3">
<a ui-sref="orderForm.step2"
ng-click="sortType ='name'"
class="btn btn-block btn-info">
Title
<span class="glyphicon glyphicon-circle-arrow-right"></span>
</a>
</div>
<h1>Presorted</h1>
<pre>{{sortType}}</pre>
</div>
这是我的第二页:
<div class="form-group" ng-controller="formController">
<h2> Sort type: </h2>
<pre>{{sortType}}</pre>
<table class="table table-bordered table-striped">
<thead>
<tr>
<td>
<label>Beverage</label>
</td>
<td>
<label>Type</label>
</td>
<td>
<label>Popularity</label>
</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="drink in drinks | orderBy: sortType | filter:searchDrink">
<td>{{drink.name}}</td>
<td>{{drink.type}}</td>
<td>{{drink.popularity}}</td>
</tr>
</tbody>
</table>
</div>
这是我的App.js页面:
angular.module('myApp', ['ngAnimate', 'ui.router'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('orderForm', {
url: '/orderForm',
templateUrl: 'orderForm.html',
controller: 'formController'
})
.state('orderForm.step1', {
url: '/step1',
templateUrl: 'step1.html'
})
.state('orderForm.step2', {
url: '/step2',
templateUrl: 'step2.html'
});
$urlRouterProvider.otherwise('/orderForm/step1');
})
.controller('formController', function($scope) {
$scope.formData = {};
$scope.processForm = function() {
alert('Thank you!');
};
$scope.sortType = '';
$scope.sortReverse = false;
$scope.searchDrink = '';
//Lists of Drinks:
$scope.drinks = [
{name:'Americano', type: 'Espresso Beverage', popularity: 4},
{name:'Raspberry Tea', type: 'Tea', popularity: 2},
{name:'Vanilla Latte', type: 'Espresso Beverage', popularity: 3 },
{name:'Mocha', type: 'Espresso Beverage', popularity: 8},
{name:'Pike', type: 'Freshly Brewed Coffee', popularity: 6},
{name:'Green Tea', type: 'Tea', popularity: 4},
{name:'Frappuccino', type: 'Iced Drinks', popularity: 5},
{name:'Fruit Smoothie', type: 'Iced Drinks', popularity: 6}
];
});
最佳答案
当您使用UiRouter进行路由时,每次在页面之间调用控制器时(在这种情况下),它将初始化您的控制器。
这里需要的是一个将保留您的值的服务,因为该服务仅实例化一次(单例)。
