如何在更改AngularJS中的选择框内容时重新加载不同控制器的嵌套状态?
我有2个选择框 1.Category和 2.SubCategory
根据类别和子类别,产品将显示在内部状态
类别和子类别属于addproducts state
产品属于addproducts状态下的.productsettings状态
但我的问题是,当我选择类别和子类别时,将显示产品 这意味着
$state.go('addproducts.productsettings');
会起作用,但在之后选择两者时,我只更改子类别选择框时,它将不会重新加载产品状态
$state.go('addproducts.productsettings');
将无法在ProductSettingsController中加载
这是我的html代码,它包含两个选择框
<form>
<div class="form-group">
<label for="exampleSelect1"><b>Category</b></label>
<select ng-model="selectedCategory" class="form-control" id="categories" ng-init="selectedCategory = null"
ng-change="onCategoryChange(selectedCategory)">
<option value="">--Select--</option>
<option ng-repeat="(key,value) in categories | orderBy:'catName'| groupBy:'catName'">{{key}}</option>
</select>
</div>
</form>
<!-- ----------------------------------- -->
</div>
<div class="col-md-3">
<!-- ----------------------------------- -->
<form>
<div class="form-group">
<label for="exampleSelect1"><b>SubCategory</b></label>
<select class="form-control" id="subcategories" ng-model="selectedSubCategory" ng-disabled="!selectedCategory"
ng-options="categories.subCatName for categories in categories | filter: {catName:selectedCategory}" ng-change="getValue()">
<option value="">--Select--</option>
</select>
</div>
</form>
<!-- ----------------------------------- -->
</div>
这是我的js代码
var appshop = angular.module('appShop', [ 'ui.router', 'angular.filter' ]);
appshop.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/category');
$stateProvider.state('addproducts',
{
url : '/addproducts',
views :
{
'body' :
{
templateUrl : 'category/manageproduct.htm',
controller : 'AddProductController'
}
}
})
.state('addproducts.productsettings',
{
url : '/productsettings',
views :
{
'productsbody@addproducts' :
{
templateUrl : 'category/productsettings.htm',
controller : 'ProductsSettingsController'
}
}
})
});
//==========================================================
appshop.controller('AddProductController',AddProductController);
function AddProductController($scope, $http,$state)
{
$scope.onCategoryChange = function(category)
{
if (!category)
{
$scope.selectedSubCategory = undefined;
}
}
var categoryPromise = $http.get("../rest/mcategory");
categoryPromise.success(function(data, status, headers, config)
{
$scope.categories=data;
});
categoryPromise.error(function(data, status, headers, config)
{
alert("Error");
});
$scope.getValue=function()
{
$state.go('addproducts.productsettings');
}
}
//==========================================================
appshop.controller('ProductSettingsController',ProductSettingsController);
function ProductSettingsController($scope,$http,$state)
{
alert("Clicked")//I need to get alert here
}
这两个选择框属于AddProductController
产品是在此AddProductController的嵌套状态下进行的,它被命名为ProductSettingsController
当我选择类别和子类别时,它可以正常工作
但是在选择了两个之后只改变了子类别它不会起作用
在选择subcatname时获取产品详细信息的任何想法?我需要在ProductSettingsController中点击提示 当我在子类别选择框中更改
