Knockout data-bind disable. With two conditions

Question

Is it possible to use || operator in disable like this:

data-bind="click: createSubActivity, disable: isDeliveryHistory || isTimeAndMaterialLocked"

I have tried, but it seems like it doesn't work.

Answer 1

If isDeliveryHistory and isTimeAndMaterialLocked are observables, you should use them like this:

data-bind="click: createSubActivity, disable: isDeliveryHistory() || isTimeAndMaterialLocked()"
