It is usually hooked up to your kitchen sink p-trap or garburator under the sink, which is vented. This is the only vent you need for drainage.

Do you need a dishwasher vent in Washington?
It is called an air-gap not a vent. If you are asking about Washington State the answer is yes it is required.
Can you eliminate the air vent on top of sink for a dishwasher?
Yes, the air vent (air gap) is very much required!! It prevents water from traveling from the sink drain pipe or garbage disposal and into the dishwasher.
Do you need an air vent installed for the dishwasher and garbage disposal and if so can it be installed another way if needed?
Your kitchen sink should already be vented if there is a p-trap draining to the wall. if it is an s-trap it is not vented and not to present code requirements. The dishwasher drain goes into the side of the disposal and the disposal should drain to the trap. A separate vent is not required for the disposal or dishwasher as the trap for the sink is what requires a vent.

This is generally a local code thing. We do not require it in our area and a loop is acceptable. Check with your code guy!
How can you fix a dishwasher that has garbage disposal water in it?

Can you install a new faucet with an extra spray outlet and use the dishwasher vent hole in the sink thereby connecting the dishwasher drain directly to the disposal?
Not sure what you mean by dishwasher vent hole, but you probably mean the air gap fitting. Some dishwashers connect directly to the disposal, with the tube going up a little to prevent stuff from going back to the dishwasher. But as for removing the air gap fitting, if you have it already, it may depend on where you are. California plumbing code requires a dishwasher air gap fitting above the flood level rim, even if you have a disposer, but I'm not sure if the national code also requires. In any case, if a code requires it, it may be a good idea not to remove the air vent. I would check your local code. You may want to consider a faucet with a built in sprayer instead.
