我正在尝试使用backbone.js model.set属性.第二个警报功能应在实现todo1.set后触发.但事实并非如此.

var Todo = Backbone.Model.extend({
defaults: {
title: "Harsh",completed: false
},initialize: function() {
console.log('This model has been initialized.')
}
});
var todo2 = new Todo({
title: 'Set through instantiation.',completed: true
});
console.log('Todo title: ' + todo2.get('title'));
console.log('Todo completed ' + todo2.get('completed'));
alert("ok");
todo2.set("title",'Title set');
alert("ok");
console.log(todo2.get('title'));
todo.set("completed",false);
console.log('completed: ' + todo2.get('completed'));
解决方法
您应该单独传递一个对象而不是参数.
todo2.set({"title":'Title set'});
