Fill in multiple text fields based on selection from drop-down

Hello.  I am attempting to have 3-6 different text fields automatically populate with pre-determined information based on the user's selection in a drop-down menu.  For example, my drop down will have Red, Blue, Green, Yellow.  If the user selects Red, then Text1 will fill in Apple, Text2 will fill in Fire Truck, Text3 will fill in Rose and Text4 will fill in Tomato.  If the user selects Yellow from the Drop Down, then Text1 is banana, Text2 is sun, Text3 is also banana and Text4 is lemon.  I know it involves JavaScprit, but to be honest, I'm a novice when it comes to that.  Any help would be greatly appreciated!
