我正在使用Backbone Marionettes CollectionView。我试图指示该集合正在加载,所以我正在使用emptyView显示加载器。
但是,这是错误的逻辑,因为有时集合为空,因此它成为损坏的加载器。
我尝试使用此脚本,但没有成功:https://github.com/surevine/marionette-loadingview-plugin
有谁有更好的解决方案?这是我当前的代码:
//loadingview
define(["marionette", "text!app/templates/loading.html"], function(Marionette, Template) {
"use strict";
return Backbone.Marionette.ItemView.extend({
template: Template
});
})
//collection
define(["marionette", "text!app/templates/events/collection.html", "app/collections/events", "app/views/events/item", 'app/views/loading'], function (Marionette, Template, Collection, Row, LoadingView) {
"use strict"
return Backbone.Marionette.CompositeView.extend({
template: Template,
itemView: Row,
itemViewContainer: "ul",
emptyView: LoadingView,
initialize: function () {
this.collection = new Collection()
return this.collection.fetch()
}
})
})
//item
define(["marionette", "text!app/templates/events/item.html"], function(Marionette, Template) {
"use strict";
return Backbone.Marionette.ItemView.extend({
template: Template,
tagName: "li"
})
})
最佳答案
我通常要做的是监听Collection/Model的“request”和“sync”事件。像这样的东西:
var View = Backbone.Marionette.CompositeView.extend({
template: Template,
itemView: Row,
itemViewContainer: "ul",
collectionEvents: {
'request': 'showLoading',
'sync': 'hideLoading'
},
initialize: function () {
this.collection = new Collection();
return this.collection.fetch();
}
showLoading: function() {
this.$el.addClass('loading');
},
hideLoading: function() {
this.$el.removeClass('loading');
}
});
