我正在尝试backbonejs,但被困在如何将模型绑定到视图上。
yepnope({
load : ["/static/js/lib/jquery-1.6.2.min.js", "/static/js/lib/underscore-min.js", "/static/js/lib/backbone-min.js"],
complete: nameList
});
function nameList() {
var PageItem = Backbone.Model.extend({
defaults: {name: "default name" }
});
var Page = Backbone.Collection.extend({
model: PageItem
});
var page = new Page;
var AppView = Backbone.View.extend({
el: $("#names"),
$artistList: $('#names_list'),
$inputField: $('input#new_name'),
events: {
"keypress input": "processKeyPress"
},
processKeyPress: function(event){
if(event.charCode == 13) {
event.preventDefault();
this.addName();
}
},
addName: function(event) {
var newName = this.$inputField.val();
this.$artistList.prepend('<li>' + newName + '</li>');
page.push(new PageItem({name: newName}));
// I've also tried page.push({name: newName});
} });
var app = new AppView;}
当我在输入字段上按 Enter 键时,它运行调用 addName 的 processKeyPress,新名称被添加到 html 列表中,但不会推送到模型上。我不断得到:
Uncaught TypeError: Object function (a){return new l(a)} has no method 'isObject'
