问题描述
我绑定在我的骨干机型像这样的更改事件。
I bind on the change event of my backbone models like this.
this.model.on( "change", this.render, this );
有时候，我想获取最新版本的模型，并强行渲染视图。所以，我这样做
Sometimes I want to fetch the latest version of the model and forcibly render the view. So I do this
this.model.fetch();
不幸的是model.fetch（）只有当新的数据是什么pviously存储在模型$ P $不同的触发更改事件。
Unfortunately model.fetch() only fires the change event if the new data is different from what was previously stored in the model.
如何能随时触发this.render回调获取完成时，它是否会触发change事件或不？
How can I always trigger a this.render callback when fetch completes, whether it triggers a change event or not?

推荐答案
您可以使用 $。阿贾克斯成功回调，但你也可以只听为主干同步和错误在模型上的事件。 同步成功调用服务器后火灾，失败的调用服务器后错误火灾。
You can use the $.ajax success callback, but you can also just listen for the Backbone sync and error events on the model. sync fires after a successful call to the server, error fires after a failed call to the server.
this.model.on('sync', this.render, this);
this.model.on('error', this.handleError, this);
