Uncaught TypeError: Object [object DOMWindow] has no method 'set' on backbone-min.js

I am receiving this error message when including backbone in my application,

Uncaught TypeError: Object [object DOMWindow] has no method 'set'

but I have jquery (1.4.4) and underscore.js (开发者_开发问答1.1.7) loaded before backbone, why is this method still missing?

Or you are instantiating a model without new prefix which would cause it to be bound to global window instead of this. SO reference.

Based solely on the error message, I would search your code for this.set. It appears that you're referencing thiswith the expectation that it's a model, but the function isn't bound correctly.
