javascript - 获取 Backbone 集合时出错: A "url" property or function must be specified

Question

我尝试获取一个简单的 Backbone Collection，但出现以下错误。

A "url" property or function must be specified

var Collection = Backbone.Collection.extend({url: '/path/toCollection'});
var collection = new Collection([]);
app.vent.bindTo('applicationDidBecomeActive', collection.fetch);
app.vent.trigger('applicationDidBecomeActive');
//Error: A "url" property or function must be specified

Answer 1

您是否需要绑定(bind)“this”参数？

app.vent.bindTo('applicationDidBecomeActive', collection.fetch, collection);
