コレクションで定義されたコンパレータ関数を使用する Backbone.js プロジェクトがあります。ページが更新されたときにアイテムを並べ替えますが、ページの更新ではなくボタンをクリックしたときに並べ替えようとしています。これが私のコードです:
var Thing = Backbone.Model.extend({
defaults: {
title: 'blank',
rank: ''
}
});
var ThingView = Backbone.View.extend({
className: 'thingClass',
template: _.template('<b><button id="remove">X</button> <b><button id="edit">Edit</button> <%= title %> Rank:<%= rank %></b>'),
editTemplate: _.template('<input class="name" value="<%= name %>" /><button id="save">Save</button>'),
events: {
"click #remove": "deleteItem",
"click #edit": "editItem",
"click #save": "saveItem",
},
deleteItem: function () {
console.log('deleted');
this.model.destroy();
this.remove();
},
editItem: function () {
console.log('editing');
this.$el.html(this.editTemplate(this.model.toJSON()));
},
saveItem: function () {
console.log('saved');
editTitle = $('input.name').val();
console.log(editTitle);
this.model.save({
title: editTitle
});
this.$el.html(this.template(this.model.toJSON()));
},
render: function () {
var attributes = this.model.toJSON();
//console.log (attributes);
this.$el.append(this.template(attributes));
return this;
}
});
var ThingsList = Backbone.Collection.extend({
model: Thing,
localStorage: new Store("store-name"),
comparator: function(thing) {
return thing.get('rank');
},
});
var thingsList = new ThingsList;
var ThingsListView = Backbone.View.extend({
el: $('body'),
events: {
'click #add': 'insertItem',
'click #sort': 'sortItems',
},
initialize: function () {
thingsList.fetch();
thingsList.toJSON();
this.render();
this.collection.on("add", this.renderThing, this);
this.collection.on("reset", this.clearRender, this);
},
insertItem: function (e) {
newTitle = $('#new-item').val();
newRank = $('#rank').val();
newThing = new Thing({
title: newTitle,
rank: newRank
});
this.collection.add(newThing);
newThing.save();
console.log(this.collection.length);
},
sortItems: function (e) {
console.log('clicked sort button');
this.collection.sort();
this.$el.detach('.item');
},
render: function () {
_.each(this.collection.models, function (items) {
this.renderThing(items);
}, this);
},
renderThing: function (items) {
var thingView = new ThingView({
model: items
});
this.$el.append(thingView.render().el);
},
clearRender: function () {
console.log('clear render called')
_.each(this.collection.models, function (items) {
//this.remove();
this.$el.remove(".thingClass")
this.renderThing(items);
}, this);
},
test: function (items) {
console.log('test worked');
},
});
var thingsListView = new ThingsListView({
collection: thingsList
});
