How to clear views before rendering another one? Backbone.js

javascriptbackbone.js

提问by fancy

Multiple view instances are happening in my application when I change layouts. I think it's possibly because they use the same elbut I'm not sure. How would I go about clearing out views before setting up new ones? Or should I create wrapper elelement for each one and clear them from the dom instead?

当我更改布局时,我的应用程序中会发生多个视图实例。我认为这可能是因为他们使用相同的el但我不确定。在设置新视图之前,我将如何清除视图?或者我应该el为每个元素创建包装元素并从 dom 中清除它们?

Thanks!

谢谢!
