我想fetch
在Backbone Collection上触发方法,它会传递类似于发生的Id参数Model.fetch(id)
例如
var someFoo= new Foo({id: '1234'});// Where Foo is a Backbone Model someFoo.fetch();
我的Backbone系列: -
var tasks = backbone.Collection.extend({ model: taskModel, url: '/MyController/GetTasks', initialize: function () { return this; } });
在我的视图中,当我尝试获取数据时: -
var _dummyId = 10; // // Tried approach 1 && It calls an api without any `id` parameter, so I get 500 (Internal Server Error). this.collection.fetch(_dummyId); // Tried approach 2 && which fires API call passing Id, but just after that // I am getting error as below:- Uncaught TypeError: object is not a function this.collection.fetch({ data: { id: _dummyId } });
发现它很晚:为了缩短上面的故事我想要像骨干中的Get/collection/id这样的东西.
感谢您的回答,最后我从Backbone.js集合选项中获得了解决方案.
抱歉,我无法正确地解释这个问题,而对于同样的要求,其他人已经做得非常聪明.
解决方案:我可以有类似的东西: -
var Messages = Backbone.Collection.extend({ initialize: function(models, options) { this.id = options.id; }, url: function() { return '/messages/' + this.id; }, model: Message, }); var collection = new Messages([], { id: 2 }); collection.fetch();
