javascript - Filter Backbone collection on multiple model attributes -



javascript - Filter Backbone collection on multiple model attributes -

i have bit of problem how best filter backbone collection on models attributes. setup this:

i have collection several models in it. each model has attribute wich holds array of numbers ("type"). this:

- collection - model - id: 1 - name - phone - type [3] - model - id: 2 - name - phone - type [2] - model - id: 3 - name - phone - type [1,2]

what want here able filter collections on models "type" attribute. have "type" attribute because contact list , each contact can of several types. e.g collection should able filtered on unlimited types. should able filter on lets type "1" , type "2" wich show model 2 , model 3. cause model 1 not have "type" 1.

any code examples or other help on great. thanks!
