我尝试了以下方法为我的模型设置一个id：
var globalCounter = 1;
var Model = Backbone.Model.extend({
initialize: function () {
this.id = globalCounter;
globalCounter += 1;
}
});
myModel = new Model();
console.log(myMode.get('id')); // prints undefined
如何为我的模型设置ID？
解决方法
您需要使用
set()功能(

var globalCounter = 1;
var Model = Backbone.Model.extend({
initialize: function () {
this.set('id',globalCounter);
globalCounter += 1;
}
});
myModel = new Model();
console.log(myModel.get('id')); // prints 1
