为什么在收集工作成功时会引发额外活动?
原标题:Why doesn t add event be triggered when Collection fetch successfully?
var documents = new Backbone.Collection();  
documents.url = "/documents";  

documents.bind("add", function(doc){
    console.log(doc);
});  

documents.fetch();  

为什么贴上<代码><>。 当<代码>fetch功能成功获得各种模型时触发的事件?

最佳回答

文件说:

When the model data returns from the server, the collection will reset ...
If you d like to add the incoming models to the current collection, instead of replacing the collection s contents, pass {add: true} as an option to fetch.

因此,对您问题的答复:如上。

documents.fetch({add: true});

它将做罚款。

问题回答

我认为,活动<代码>add是在你为已经有人居住的集邮增加内容之后发射的。

在这种具体情况下,你可以听取<代码>reset活动,而不是add/code>。 还记得,你收集了数据。
