Do you hear a hum when you push the washer fluid button? If not, your washer fluid pump might be broken, or you may have blown its fuse.
I'd start by checking your owner's manual for the location of your fuse box and pulling the fuse for your washer fluid pump. The location of this fuse should be marked on the back of the fuse panel cover or perhaps in the owner's manual. Once you have the fuse out, if it looks burnt or you can visibly confirm the connection has been burned-through, replace it with the proper amperage fuse and see if that fixes the problem.
If the fuse looks okay, make sure your washer fluid supply lines are still connected to the nozzles on your hood and to the washer fluid tank/pump. Or, they could have a kink or tear in them somewhere. These lines are relatively easy to find-- just trace down from the hood into the engine bay. These should be the only visible rubber hoses that connect to the hood at any point. They'll be about as big around as a pencil, perhaps even smaller, and will probably be black in color. Trace the lines down to the tank and make sure they're not disconnected, kinked, or torn anywhere.
If the lines are connected, it's possible they've been clogged. Or your nozzles might have been vandalized-- I've known of people putting glue over the nozzles just to mess with people. So check the nozzles on your hood to ensure they're clean. If they are, and if you can remove the lines where they enter the nozzles, give them a quick look to see if they appear dirty or cruddy. If so, you may need to remove the lines and blow them out/cleanse them with solvent. But this typically isn't a problem due to the alcohol in washer fluid, which tends to keep the lines pretty clean.
Finally, check the reservoir. If it looks dirty at the bottom, it's possible you've got a clog. Otherwise, I'd say to have your washer fluid pump checked out by a trusted handyman or local mechanic. It should be a fairly cheap repair, if that is determined to be the cause.
