console.log主干模型，attributes属性

Question

I wanted to make sure I understood Firebug correctly. I print out my model. And in the console of firebug, I see in the attributes, it has "myProperty". But then when I do this:

if (_.has(model, "myProperty"))

or

if (model.hasOwnProperty('myProperty'))

Both do not return a result. Is there somethign I'm not understanding about Firebug or JS? Thanks.

Answer 1

If myProperty is an attribute you've given the model, then it will exist in the attributes object: model.attributes.myProperty . Does it?

Note that in the docs , if myProperty is null or undefined then model.has(myProperty) will return false .
