我想在页面顶部创建一个固定位置的导航菜单，单击相关链接后应该显示不同的 View 。我有一个index.php 文件、一个mainpage.js 文件以及用于集合、模型、 View 、路由器和html 模板的单独文件夹。到目前为止，显示菜单和 View 都有效，只是导航不起作用，例如我不知道如何让它正常工作。导航栏应该始终可见，#mainContent Div 应该显示不同的 View ...
我的index.php(正文部分):
<body>
<div id="container">
<div id="mainMenu"></div>
<div id="mainContent"></div>
</div>
<script data-main="js/config" src="js/lib/requirejs/require.js"></script>
<script> require(['config'], function(config) {
require(['app/mainpage']);
});
</script>
</body>
所以我创建了一个 MainMenuCollection,json 文件:
[
{
"name":"HOME",
"id":"1",
"url":"home"
},
{
"name":"FIRST PAGE",
"id":"2",
"url":"firstpage"
},
{
"name":"SECOND PAGE",
"id":"3",
"url":"secondpage"
},
{
"name":"THIRD PAGE",
"id":"4",
"url":"thirdpage"
},
{
"name":"ABOUT",
"id":"5",
"url":"about"
},
{
"name":"CONTACT",
"id":"6",
"url":"contact"
}
]
我的收藏文件:
define([
"backbone",
"models/MainMenuModel"
],
function(Backbone, MainMenuModel) {
var MainMenuCollection = Backbone.Collection.extend({
model: MainMenuModel,
url: "MainMenuCollection.json"
});
return MainMenuCollection;
});
我的菜单模型:
define([
"jquery",
"backbone"
],
function($, Backbone) {
var MainMenuModel = Backbone.Model.extend({
urlRoot: "/MainMenuCollection.json"
});
return MainMenuModel;
});
这是我的 Menu.html 文件:
<ul>
{{#each mainmenu}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
菜单 View 本身:
define(['backbone','handlebars', 'text!templates/MainMenu.html'],
function(Backbone,Handlebars, Template) {
'use strict';
var MainMenuView = Backbone.View.extend({
template: Handlebars.compile(Template),
events: {
'click a':'mainMenu_event'
},
mainMenu_event: function(e) {
var id = $(e.currentTarget).attr('href');
Backbone.history.navigate(id, {trigger:true});
},
initialize: function () {
},
render: function() {
//this.model.toJSON())
$(this.el).html(this.template({mainmenu:this.collection.toJSON()}));
return this;
}
});
return MainMenuView;
}
);
最后是路由器:
define([
'backbone',
//
'views/MainMenu',
'views/Home',
'views/Firstpage',
'views/Secondpage',
'views/Thirdpage',
'views/About',
'views/Contact',
'collections/MainMenuCollection'
],
function(
Backbone,
MainMenuView,
HomeView,
FirstpageView,
SecondpageView,
ThirdpageView,
AboutView,
ContactView,
MainMenuCollection
) {
'use strict';
var Router = Backbone.Router.extend({
routes: {
'': 'index',
'pages/firstpage' : 'firstpage',
'pages/secondpage' : 'secondpage'
},
//Initializing the application
initialize: function () {
var self = this;
//Collections
this.mainMenuCollection = new MainMenuCollection();
//Views
this.mainMenuView = new MainMenuView({el:'#mainMenu', collection:this.mainMenuCollection});
this.homeView = new HomeView({el:'#mainContent'});
//this.menuView = new Menu({el:'.menu'});
self.homeView.render();
//self.gridView.render();
this.mainMenuCollection.fetch({success: function(collection) {
self.mainMenuView.collection=collection;
self.mainMenuView.render();
}});
Backbone.history.start({
pushState: false
});
},
//Default route.
index: function () {
var self = this;
},
firstpage: function() {
this.firstpageView = new FirstpageView({el:'#mainContent'});
self.firstpageView.render();
},
secondpage: function() {
this.secondpageView = new SecondpageView({el:'#mainContent'});
self.secondpageView.render();
}
});
return Router;
}
);
我的问题是，我不知道如何浏览不同的页面/ View ，所以如果有人可以帮助我吗？如何设置路由器？帮助会很棒! :-)
最佳答案
[更新] 好的，我自己得到了:
因为我的路由器中有“页面”作为引用:
routes: {
'': 'index',
'pages/firstpage' : 'firstpage',
'pages/secondpage' : 'secondpage'
},
我所要做的就是在html文件中， anchor 是:
<a href="#pages/{{this.url}}">{{this.name}}</a>
