我有一个完美的布局视图。在四个子视图中的一个中,有一个用于创建“事件”的按钮。单击时,我希望子视图被单独的添加事件视图替换。
我不确定添加事件视图是在主布局逻辑中还是在子视图中触发。
index.js(布局父视图)
define([
"marionette",
'app/views/images/collection',
'app/views/topPosts/collection',
'app/views/clients/collection',
'app/views/events/collection',
"tpl!app/templates/index.html"
],
function(Marionette, ImagesView, TopPostsView, ClientsView, EventsView, template) {
"use strict";
var AppLayout, layout;
AppLayout = Backbone.Marionette.Layout.extend({
template: template(),
regions: {
collection1: '#images',
collection2: '#topPosts',
collection3: '#clients',
collection4: '#events'
},
onRender: function() {
this.collection1.show(new ImagesView())
this.collection2.show(new TopPostsView())
this.collection3.show(new ClientsView())
this.collection4.show(new EventsView())
}
})
return new AppLayout()
})
event / collection.js(我相信它会触发替换视图)
define(["marionette", "text!app/templates/events/collection.html", "app/collections/events", "app/views/events/item", 'app/views/events/create'], function (Marionette, Template, Collection, Row, CreateEventView) {
"use strict"
return Backbone.Marionette.CompositeView.extend({
template: Template,
itemView: Row,
itemViewContainer: "ul",
events: {
'click #createEvent': 'onClickCreateEvent'
},
onClickCreateEvent: function () {
//render create form over the events collection
},
initialize: function () {
this.collection = new Collection()
return this.collection.fetch()
}
})
})
event / item.js(上面集合的模型视图)
define(["marionette", "text!app/templates/events/item.html"], function(Marionette, Template) {
"use strict";
return Backbone.Marionette.ItemView.extend({
template: Template,
tagName: "li"
})
})
我尝试将其放在event / collection.js中,但它只是删除了项目视图
onClickCreateEvent: function () {
this.$el = new CreateEventView().$el
this.$el.render(); return this;
},
答案 0 :(得分:2)
将在包含单击元素的视图中触发事件。但是,只要您未在事件上调用stopPropagation()
,事件就会传播到父视图。但是,CompositeView不应该负责替换自己;应该对父视图负责(我相信AppLayout
)。处理视图交换的一种方法是:
// index.js
AppLayout = Backbone.Marionette.Layout.extend({
...
events: {
'click #createEvent': 'onClickCreateEvent'
},
...
onClickCreateEvent: function(e) {
this.collection4.show(new CreateEventsView());
},
...
这种方法的一个缺点是,您绑定事件的DOM元素与该Layout的模板没有直接关系。
