以前有人问过，答案看起来不好看。 我想要考虑这个示例代码...
我的应用程序在提供它的服务中加载当前项目。 有几个控制器在不重新加载物品的情况下操纵物料数据。
如果尚未设置，我的控制器将重新加载该项目，否则将使用服务中当前加载的项目，在控制器之间。
问题 ：我想为每个控制器使用不同的路径，而不重新加载Item.html。
1）这可能吗？
2）如果这是不可能的，是否有更好的方法来获得每个控制器的路径，我在这里提出了什么？
app.js
var app = angular.module('myModule', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/items', {templateUrl: 'partials/items.html', controller: ItemsCtrl}).
when('/items/:itemId/foo', {templateUrl: 'partials/item.html', controller: ItemFooCtrl}).
when('/items/:itemId/bar', {templateUrl: 'partials/item.html', controller: ItemBarCtrl}).
otherwise({redirectTo: '/items'});
}]);
Item.html
<!-- Menu -->
<a id="fooTab" my-active-directive="view.name" href="#/item/{{item.id}}/foo">Foo</a>
<a id="barTab" my-active-directive="view.name" href="#/item/{{item.id}}/bar">Bar</a>
<!-- Content -->
<div class="content" ng-include="" src="view.template"></div>
controller.js
// Helper function to load $scope.item if refresh or directly linked
function itemCtrlInit($scope, $routeParams, MyService) {
$scope.item = MyService.currentItem;
if (!$scope.item) {
MyService.currentItem = MyService.get({itemId: $routeParams.itemId});
$scope.item = MyService.currentItem;
}
}
function itemFooCtrl($scope, $routeParams, MyService) {
$scope.view = {name: 'foo', template: 'partials/itemFoo.html'};
itemCtrlInit($scope, $routeParams, MyService);
}
function itemBarCtrl($scope, $routeParams, MyService) {
$scope.view = {name: 'bar', template: 'partials/itemBar.html'};
itemCtrlInit($scope, $routeParams, MyService);
}
解析度。
状态 ：按照接受的答案推荐使用搜索查询，可以让我不用重新载入主控制器来提供不同的网址。
app.js
var app = angular.module('myModule', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/items', {templateUrl: 'partials/items.html', controller: ItemsCtrl}).
when('/item/:itemId/', {templateUrl: 'partials/item.html', controller: ItemCtrl, reloadOnSearch: false}).
otherwise({redirectTo: '/items'});
}]);
Item.html
<!-- Menu -->
<dd id="fooTab" item-tab="view.name" ng-click="view = views.foo;"><a href="#/item/{{item.id}}/?view=foo">Foo</a></dd>
<dd id="barTab" item-tab="view.name" ng-click="view = views.bar;"><a href="#/item/{{item.id}}/?view=foo">Bar</a></dd>
<!-- Content -->
<div class="content" ng-include="" src="view.template"></div>
controller.js
function ItemCtrl($scope, $routeParams, Appts) {
$scope.views = {
foo: {name: 'foo', template: 'partials/itemFoo.html'},
bar: {name: 'bar', template: 'partials/itemBar.html'},
}
$scope.view = $scope.views[$routeParams.view];
}
directives.js
app.directive('itemTab', function(){
return function(scope, elem, attrs) {
scope.$watch(attrs.itemTab, function(val) {
if (val+'Tab' == attrs.id) {
elem.addClass('active');
} else {
elem.removeClass('active');
}
});
}
});
我的部分内容包含ng-controller=...
It's been asked before, and from the answers it doesn't look good. I'd like to ask with this sample code in consideration...
My app loads the current item in the service that provides it. There are several controllers that manipulate the item data without the item being reloaded.
My controllers will reload the item if it's not set yet, otherwise, it will use the currently loaded item from the service, between controllers.
Problem: I would like to use different paths for each controller without reloading Item.html.
1) Is that possible?
2) If that is not possible, is there a better approach to having a path per controller vs what I came up with here?
app.js
var app = angular.module('myModule', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/items', {templateUrl: 'partials/items.html', controller: ItemsCtrl}).
when('/items/:itemId/foo', {templateUrl: 'partials/item.html', controller: ItemFooCtrl}).
when('/items/:itemId/bar', {templateUrl: 'partials/item.html', controller: ItemBarCtrl}).
otherwise({redirectTo: '/items'});
}]);
Item.html
<!-- Menu -->
<a id="fooTab" my-active-directive="view.name" href="#/item/{{item.id}}/foo">Foo</a>
<a id="barTab" my-active-directive="view.name" href="#/item/{{item.id}}/bar">Bar</a>
<!-- Content -->
<div class="content" ng-include="" src="view.template"></div>
controller.js
// Helper function to load $scope.item if refresh or directly linked
function itemCtrlInit($scope, $routeParams, MyService) {
$scope.item = MyService.currentItem;
if (!$scope.item) {
MyService.currentItem = MyService.get({itemId: $routeParams.itemId});
$scope.item = MyService.currentItem;
}
}
function itemFooCtrl($scope, $routeParams, MyService) {
$scope.view = {name: 'foo', template: 'partials/itemFoo.html'};
itemCtrlInit($scope, $routeParams, MyService);
}
function itemBarCtrl($scope, $routeParams, MyService) {
$scope.view = {name: 'bar', template: 'partials/itemBar.html'};
itemCtrlInit($scope, $routeParams, MyService);
}
Resolution.
Status: Using search query as recommended in the accepted answer allowed me to provide different urls without reloading the main controller.
app.js
var app = angular.module('myModule', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/items', {templateUrl: 'partials/items.html', controller: ItemsCtrl}).
when('/item/:itemId/', {templateUrl: 'partials/item.html', controller: ItemCtrl, reloadOnSearch: false}).
otherwise({redirectTo: '/items'});
}]);
Item.html
<!-- Menu -->
<dd id="fooTab" item-tab="view.name" ng-click="view = views.foo;"><a href="#/item/{{item.id}}/?view=foo">Foo</a></dd>
<dd id="barTab" item-tab="view.name" ng-click="view = views.bar;"><a href="#/item/{{item.id}}/?view=foo">Bar</a></dd>
<!-- Content -->
<div class="content" ng-include="" src="view.template"></div>
controller.js
function ItemCtrl($scope, $routeParams, Appts) {
$scope.views = {
foo: {name: 'foo', template: 'partials/itemFoo.html'},
bar: {name: 'bar', template: 'partials/itemBar.html'},
}
$scope.view = $scope.views[$routeParams.view];
}
directives.js
app.directive('itemTab', function(){
return function(scope, elem, attrs) {
scope.$watch(attrs.itemTab, function(val) {
if (val+'Tab' == attrs.id) {
elem.addClass('active');
} else {
elem.removeClass('active');
}
});
}
});
The content inside my partials are wrapped with ng-controller=...
最满意答案
如果你不必使用像#/item/{{item.id}}/foo和#/item/{{item.id}}/bar但#/item/{{item.id}}/?foo和#/item/{{item.id}}/?bar ，可以为/item/{{item.id}}/设置路由，使reloadOnSearch设置为false（ docs.angularjs.org/ api / ngRoute。$ routeProvider ）。 这告诉AngularJS如果url的搜索部分更改，不重新加载视图。
If you don't have to use URLs like #/item/{{item.id}}/foo and #/item/{{item.id}}/bar but #/item/{{item.id}}/?foo and #/item/{{item.id}}/?bar instead, you can set up your route for /item/{{item.id}}/ to have reloadOnSearch set to false (https://docs.angularjs.org/api/ngRoute/provider/$routeProvider). That tells AngularJS to not reload the view if the search part of the url changes.
