骨干网：如何在与View关联的元素之外操作元素

Question

My html structure is:

<div id="header">
</div>

<div id="screen">
</div>

My Backbone View is associated with screen. How to hide/show element in header?

Answer 1

The direct answer is:

There's nothing special backbone will do for you here. Do it like you would do had backbone not existed at all.

The correct answer is:

If you need to manipulate UI elements outside of your view model, your view model is wrong - fix it.

Answer 2

According to the backbone structure & logic - your headerview or screenview should throw an event, in which header view should listen to. If that event happens - then headerview should hide itself.
