我仍在尝试从我的收藏中删除(销毁)模型。数据被分组并呈现为手风琴风格。但是当我在控制台中单击 X 时,请注意:
Uncaught Uncaught TypeError: Cannot call method 'destroy' of undefined
(function() {
window.App = {
Models: {},
Collections: {},
Views: {},
Router: {}
};
window.vent = _.extend({}, Backbone.Events);
})();
// !models.js
App.Models.Item = Backbone.Model.extend({});
// !collections.js
App.Collections.Items = Backbone.Collection.extend({
model: App.Models.Item,
url: 'api/items.json'
});
// !views.js
App.Views.Items = Backbone.View.extend({
el: '#items',
events: {
'click .cccc':'deleteItem',
},
deleteItem: function() {
this.model.destroy();
},
initialize: function() {
this.listenTo( this.collection, "change", this.render );
this.template = _.template( document.getElementById('productsCategoriesTemlate').innerHTML );
this.render();
this.$el.accordion({ animate: 0 });
},
getGroups : function(){
return _.groupBy(this.collection.toJSON(), 'category');
},
render: function() {
this.el.innerHTML = this.template({ data : this.getGroups() });
},
addOne: function(item) {
// ????????????

App.Views.Item = Backbone.View.extend({
deleteItem: function() {
this.model.destroy();
},
// ???????????
});
// !router.js
App.Router = Backbone.Router.extend({
routes: {
'':'index',
},
index: function() {
console.log('index page !');
},
});
new App.Router;
Backbone.history.start();
App.items = new App.Collections.Items;
App.items.fetch().then(function() {
new App.Views.Items({ collection: App.items });
});
模板 :
<script id="productsCategoriesTemlate" type="text/template">
<% _.each( data, function( category, i ){ %>
<h3 class="category-name"><%= i %></h3>
<div><% _.each( category, function( item ){ %>
<li class="product"><%= item.title %><p style="float:right;" class="cccc">X</p></li>
<% }) %>
</div>
<% }) %>
</script>
